It’s on again, our March Madness sale. Purchase any welding machine valued at over $1500 and we will give you a Blue Metalmaster Fabricator Automatic Welding Helmet and a Welding Cart absolutely free. That’s $198 added value plus free delivery on those items free of charge.
You may have recently purchased a welding machine, perhaps a mig or tig welder or even an arc inverter welder and you have plans for the very first project. You plan to build a welding table. You are not alone in this as it is a very blokey thing to do. After you consider the cost of materials, the time to cut it up and weld it all together you may instead opt for the Nomad Welding Table from Stronghand Tools USA.
At $295 including GST and free delivery to your door, the Nomad Welding Table is a sound investment. It features adjustable height and also adjustable tilt. It can be expanded in length by using two tables together with a connector plate in between. The connector plate is just another table top only without the legs so you end up with something that is 3 times longer than just one table on it’s own.
There are slots in the table that are designed to allow the insertion of many of the stronghand welding clamps and welding pliers to keep your work piece in position whilst it is being welded.
Whilst making your own DIY version is a fun sounding idea, assembling one out of the box is faster and you can get down to the real business of the shed, get your mates around for a beer and throw a green felt onto the welding table for a quick card game. One of the best features of the Nomad Welding Table is that it folds away for easy storage so you need not clutter the limited space you have left in the shed.
If you would like more information, the product may be seen here or you can give our knowledgeable staff a call on 1300 881 991.
The Metalmaster 320 Pro is digitally controlled ACDC Tig welder containing an arsenal of features within a clever digital control interface. The professional features such as high frequency start, up and down slope, pre and post gas flow, start and finish currents, Multiple AC waveforms, AC + DC Hybrid wave, adjustable AC frequency with balance adjustment, adjustable pulse current, pulse duty and pulse frequency, repeat (latch) function and MMA VRD welding. This truly is the ultimate welding power source unit designed for precision AC DC TIG / MMAW welding of all weldable materials. Why spend $1000s more on a European brand when you can achieve the same result with our proven technology backed by an industry leading 5 year warranty.
The features in more detail:
AC Wave Manipulation - This unit is capable of providing a square wave, soft square wave, sine wave, trapezoidal wave for welding of aluminium.
AC + DC Hybrid Wave - Whilst pulse Tig welding the welding power source can supply the operator with AC during the pulse cycle and DC during the base cycle. This Hybrid wave allows for welding very thin aluminium at the minimum settings or much thicker aluminium at the upper settings. DC injection during an AC welding cycle increases heat input dramatically.
Huge AC & DC Pulse Frequencies - Our 32 Bit Microprocessor design allows for 0.1 to 250 Hz Pulses in AC and 0.1 to 500Hz pulses in DC.
Enhanced MMA Welding - Now featuring MMA with VRD on or VRD off, Hot Start amps, Hot Start timer and Arc force, weld like a pro in MMA.
FOD (Fan on Demand) - The fan runs as required. Once the welding stops, the fan timer spools down the high speed fan and allows the operator to think with a clear head. Silence is golden.
Quick Disconnect - Front and rear connections have a quick disconnect so packing up and moving takes seconds.
Welding For Dummies - No need to buy the book, we have added some failsafe settings that get you unstuck if you muddle up the controls. Simply select A for Ally or F for Ferous from the memory chanels and pre load our expert settings, just adjust the amps to your requirement and weld with ease.
Pre Gas Flow - Pre gas flow allows the operator to set the amount of gas flow in seconds that is required before the Tig welding arc is activated. This is ideal for purging pipes etc before welding.
Start Amps – Hot start for TIG, this sets the amount of amperage that is provided upon pressing the Tig torch trigger. This function is used in 4T mode as initial welding current or in 2T mode as the minimum start current to heat up the tungsten.
Up Slope - Increases the output amperage from the start amps setting to the welding amps setting over the time set. For example, if start crater is 30 amps and welding current is 70 amps with 5 seconds up slope time you would experience the welding arc as follows. Upon pressing the Tig torch trigger in 2T mode the current would start at 30 amps then grow steadily for 5 seconds until it reaches 70 amps. In 4T mode upon pressing the trigger the current will start at 30 amps, when the trigger is released the current would steadily increase for 5 seconds until it reaches 70 amps.
Welding Amps – This is the welding current used for non pulse welding in Tig or MMA for DC and also AC modes.
AC Balance – This setting is critical for aluminium welding and determines the amount of time electrons flow from the job to the tungsten (cleaning) as opposed to tungsten to job (penetration) as a percentage of total AC cycle. For example if set to 40%, the electrons will spend 40% of the AC welding cycle flowing from the job to the tungsten electrode and the opposite value 60% flowing from the tungsten to the job. This in effect gives an additional penetration gain over machines without balance control.
AC Frequency – The AC frequency setting changes the amount of AC cycles that occur each second. More alternating cycles has the effect of narrowing the arc which in turn increases penetration. Lowering the AC frequency broadens the arc so is ideal for internal corners.
Pulse Amps – When pulse welding thin sheet or thin walled tubes pulse welding is a technique that is used to reduce the amount of heat that is provided to the weld as an average but increases the heat provided during pulse cycles. In effect this provides better penetration whilst reducing distortion. The pulse welding current is set at a value that can penetrate the full thickness of the material and form a weld pool.
Base Amps – Base amps is used during the pulse welding procedure and sets the background current. In effect the base amps control sets the amount of amperage that is provided between pulses and this amount must be set sufficiently low that it allows the material to cool and solidify. As it is not practical to extinguish the welding arc in between pulses, the base current effectively keeps the arc active but does so at a value that will not affect the weld pool.
Pulse Ratio – The pulse ratio is the proportion of time the welding arc will pulse as opposed to not pulse. If set at 50% there will be a pulse and base current applied in equal proportions. If set to 20% there will be a pulse for 20% of the cycle and a base current for 80% of the cycle. An example of what is occurring may be calculated as follows. We may be welding 2mm sheet so could set the pulse current at 80 amps and base current at 20 amps. In normal operation an 80 amp welding current would blow a hole right through the 2mm sheet however in pulse welding mode we can pulse the 80 amps at say 30% of the time and have our base current of 20 amps for 70% of the time. The result is (80 x 0.3 = 24) + (20 x 0.7 = 14) = 38 Amps. You could not weld the material at 38 amps no matter how hard you try however using pulse welding techniques it is easy to achieve excellent penetration and do so at a reduced AVERAGE welding current.
Pulse Frequency – This is how fast the pulses repeat each second. Increasing pulse frequency can again narrow the arc slightly thus increasing penetration as the welding arc energy is concentrated into a smaller zone.
Down Slope – This is the opposite to up slope in that it decreases the output welding current over time until it arrives at the final crater current value.
Post Gas Flow - Post gas flow is used to keep the tungsten welding electrode immersed in an inert gas shield whilst it is hot. If you do not whiled the electrode it will oxidise in the atmosphere due to it’s heat when it comes into contact with oxygen. You may also hover over the weld bead during the gas post flow period to keep it shielded whilst it cools down.
Wave - For Tig welding processes, this push button selects AC welding current or DC welding current. In MMA stick welding procedures you may press the WAVE selector in order to toggle the output welding current polarity. Switching from electrode positive to electrode negative simply requires a push of this button.
Trigger – 2T or 4T selection is made by pushing this button.
In 2T mode pressing the torch trigger will initiate the pre gas flow, start the arc at start crater value, up slope, provide welding current. Releasing the button will provide down slope until final crater current value, extinguish the arc and then provide gas post flow.
In 4T mode pressing the torch trigger will initiate the pre gas flow and start the arc at start crater value. Releasing the torch trigger will up slope and provide the set welding current. At this point you will note the operator does not need to hold the torch trigger to continue welding. Pressing the Tig torch trigger again will provide down slope until final crater current value is reached. Releasing the Tig torch trigger will extinguish the arc and then provide gas post flow.
The “T” represents a change in trigger value so a push and release as in the first example is two changes hence the term 2T. In the second example the welding torch trigger was pushed, released, pushed, and released again. This was four trigger change of states hence the term 4T.
If using a variable amps remote control that is torch mounted you must do so in 4T. You simply press and release the trigger so that you do not need to hold it whilst welding. This leaves your finger free to control and vary the welding amperage of the machine. To stop the welding process simpley press and release the gig torch trigger again.
Tig / MMA Welding Mode – This push button selects the welder’s operating mode. You may select Tig welding, Pulse Tig welding and MMA / Stick welding.
Parameter Select – Pushing these buttons allows the operator to select the many adjustable parameters that are represented by an illuminated LED along the welding function line in the centre of the panel.
Parameter Adjust - This rotary encoder is used to change the value of any selected parameter. Turning will increase or decrease the value in increments of one. For increased speed of adjustment, pushing the knob whilst turning will change values in increments of 10.
Tig Start – The Tig start selector is used to inhibit the HF Tig start circuit. The operator may toggle between HF Tig start and Lift Tig start.
Memory - Memory functions are available to store settings. Use it to save favourite set up when jobbing.
Metalmaster welding machines come standard with a 5 year parts and labour warranty. All IGBT transistors are manufactured by Infineon, chosen for their ability to provide dependable power in the toughest of environments. With the Metalmaster Alupulse 320 Pro you will have one tough inverter AC DC TIG MMA welder ready to attack and conquer any welding job you put to it.
I got to thinking this morning about how digital inverter welders have impacted the product range and pricing of inverter welding machines available in Australia today. The evolution of welding machines is driven by three influencing factors.
1. The manufacturer must offer relevant and technologically advanced welding machines in order to attract customers.
2. The manufacturer must keep production costs low in order to offer competitively priced welding machines.
3. The manufacturer must consider building reliable welding machines in order for their brand to be trusted and flourish.
The diagram above shows a simplified explanation of this relationship. Enter the digital inverter welder.
Digital Inverter Welders
Digital inverter welders use microprocessors to process a program and then send signals to relevant parts of the welding power source to switch components in order to obtain the desired result. A change in the program can produce a different result without any requirement to modify the actual hardware. This is different to analogue inverter welders which contain electronic circuits made up mostly of discrete components that are hard wired to do a job and cannot be changed easily after manufacture.
The advantages offered by digital inverter welding power sources is that one control board can be used in many different welding machines be it TIG or MIG or MMA and simply changing the program can change the operational mode of the welding machine. Within the Metalmaster range of welding machines one control board and one front interface control panel is used to drive the Metalmaster Alupulse 210 Pro, Metalmaster Alupulse 320 Pro, Metalmaster 215 Elite, Metalmaster 256 Elite welding machines. Apart from the welding power source output components that control the electrical load, only the digital program and front plastic membrane differs in each of the models, the electronics behind the front panel and the main control boards are identical. This is an example of how one digital design can have multiple applications and reduce manufacturing costs.
Digital Inverter Welder Reliability
Tokentools welding machines have established a reputation in Australia of reliability and longevity. Our industry standard 5 year warranty is founded in the components used for the power train of our inverter welders. We were the first to use Infineon IGBT transistors in our welding machines whilst other manufacturers were running MOSFET output stages. Our control circuits implement Motorolla, Siemens, Fairchild, NEC components and although this drives manufacturing costs up, the reliability is increased which brings costs down overall as future cost allowance for warranty work is reduced.
The next time you are looking to buy a new welder it will be easier to decide which model and brands to pick by applying the 3 criteria outlined above. Look for the machine with the most features, best price and longest warranty. If you would like more information, please give our staff a call on 1300 991 881 or any of our state based direct in-dial numbers.
The staff at Tokentools have been working diligently to release our 250 Amp Pulse Mig Welder before Chrissy. After months of testing and program tweaks we are pleased to announce launch date is Monday 17th November 2014.
Pulse MIG welding has been simplified by allowing the operator quick access to the most recent setting so micro adjustments may be made on the fly. Different from standard MIG welding, the pulse feature allows two voltage characteristics, a ratio between them and a rate of repetition.
Peak Volts – The upper voltage that is used to provide penetration.
Base Volts – The lower voltage that is used to maintain the arc whilst allowing the material to cool.
Pulse Ratio – The amount of ratio of pulse vs base. Increasing this value gives more pulse / heat.
Pulse Frequency – The repetition rate of the pulse cycle. A value of 10Hz will provide 10 pulses per second.
Pulsed MIG welding can be used for joining both thick and thin sections of aluminium. During the pulse weld process on thicker material, a cooler weld puddle is formed when compared to the traditional spray transfer process, making it usable in all positions.
Thinner sections of aluminum benefit by the reduced risk of burn-through and warping by controlling the heat input very accurately. This control often allows for the use a larger diameter wire up to 1.2mm, which increases the rate of wire deposition and productivity. The welding operator can lay more weld metal into the joint imuch faster all without adding excessive amounts of heat. Pulsed MIG welding can also allow for faster wire feed and travel speeds, again increasing productivity, while simultaneously turning down the heat input leading to decreased residual stress and distortion.
For Tig welding processes simply connect the supplied TIG torch and press the push button trigger to activate the power output along with shielding gas, you are then ready to perform smooth lift arc TIG welding operations. When the operator touches the tungsten electrode to the workpiece the output current is reduced to only a few amps and this process avoids tungsten stick, the unfortunate result that occurs when Tig welding with a standard stick welder.Upon lifting the tungsten electrode away from the workpiece, the 32 bit microprocessor rapidly reacts and increases the current within milliseconds thereby establishing a strong Tig welding arc. The arc is further manipulated based on Tig mode, either standard or pulse. As with the Pulse MIG welding process, Pulse TIG welding provides a similar benefit for thick and thin material sections.
Huge MMA stick welding capacity is available and at 200 Amps DC, puts this 26 kilogram welding power source in the same league as Granpah’s 300 kilo, 280 Amp buzz box AC arc welder. With arc force, hot start amps and hot start time, benefit from 21st century features with the confidence of owning a product backed by an industry leading 5 year warranty.
Away from mains, no worries? Generator use is assured but a 10 Kva unit with AVR (automatic voltage regulator) is a must. A large capacity fan ensures years of high duty cycle operation. An easy to use membfane control panel and steel case will provide superior protection against accidental bumps. All IGBT transistors are manufactured by Infineon, chosen for their ability to provide dependable power in the toughest of environments. Designed for precision PULSE MIG MAG TIG and MMAW applications for all weldable materials we believe this product is being offered at a price point that is affordable and a warranty that is market leading.
Welding positioners are great tools and anyone on a tight budget in need of speeding up the the weld time of circular objects will benefit from any of the welding positioners available from Tokentools. It is important to consider the welding speed required of any object placed onto the positioner. This is easily calculated by using pi or 22/7. Take a measurement across the diameter of the object and multiply it by 3.14
The ROTA300 Welding Positioner has a minimum speed of 1 revolution in 1 minute (1 RPM) therefore a workpiece with 300mm diameter will rotate at 94.2cm per minute.
The ROTA350 Welding Positioner has a minimum speed of 1 revolution in 5 minutes (0.2 RPM) therefore a workpiece with 300mm diameter will rotate at 18.84cm per minute.
The ROTA450 Welding Positioner also has a minimum speed of 1 revolution in 5 minutes (0.2 RPM) therefore a workpiece with 300mm diameter will rotate at 18.84cm per minute.
Give our staff a call on 1300 881 991 if you need help with selecting a suitable welding positioner.

Today we sold out of our Multi Function welder, the ACDC Tig plasma called “Alusync”….again :).
A quality product with 5 year warranty backed by competent staff will always be in demand!
I am taking a moment to address one of the most common questions asked by customers about these types of welding machines. It is a question of reliability of multi process machines compared to typical ACDC machines without the plasma component. It seems there are a lot of tech jockeys out there who are experts in how these products work and their consensus is that they are no good, best avoided. The freedoms gained with the internet allows these non pier reviewed comments to take hold however in contrast our own expert and experienced voice is here to equally counter them, and conditionally neutralise them.
Cheap Welders Are Crap
If a person, lets call him “BARRY”, is going to buy a multi process ACDC tig plasma welding machine on ebay for under $600 I can guarantee it will most likely break. It will most likely break quickly and it will most likely break very loudly whilst simultaneously emitting lots of acrid black smoke. The first thing Barry will do is try to contact the seller. “OMG, my welder blew up, fix it quick”. At this point Barry realises that he only has an email address. In a panic Barry checks all his emails from ebay and paypal and cannot find a phone number nor physical store front….just the email addy that does not respond to his panicked cries of despair.
Then Barry has a rant on multiple forums and musters support, the consensus by the angry yet supportive mob is that multi process welders are crap. That’s it, no consideration for the circumstances and no thought to the fact that Barry did nothing more than the expensive equivalent of buying a $2 watch from the local discount store.
A tightwad pays twice
My mate Stewy at Titan Machinery (titanmachinery.com.au) often talks of tightwads that end up paying twice due to their frugal nature. I got to thinking about that and how the whole world of ebay affects my passionate area of interest, quality welding equipment.
Do it once, do it right, weld and cut in confidence
Tokentools welding products enjoy a pretty good reputation and it can be fully attributed to the staff and management. Of course the 5 year warranty gives confidence to new customers but the real back story is that the staff and management respond quickly and with concern to any issues that are raised. During the GFC we had a choice to go cheaper or go better and we chose to go better. We chose to pay more for better parts, thicker copper tracks, larger heat sinks, bigger fans, better torches. We invested in more R&D and now 6 years on can see the difference in the market. We are driven by quality and reliability. On the flip side ebay forces sellers to cut costs, compete with each other at unsustainable prices and offer crap to a marketplace full of consumers, like Barry that will most likely do nothing when their investment goes up in smoke.
Ok, I got a bit sidetracked and had a rant.
The Cons with multi-process welders are as follows. The market is unregulated, a lack of compliance allows for inferior poor quality and dangerous imports to be sold in *firewalled market places. *Firewalled Marketplace means a non transparent marketplace like ebay where the true identity of the seller is hidden from the buyer.
Conditionally as stated in Parra 3
The pros with multi-process welders are as follows, one machine, many tools and processes, save money. We offer a 5 year warranty on both types of machines whether they have plasma or not. We have not found any increased risk in all the years of selling them, if you pay for quality then it will last, that is the condition.

Customers often call to find out what is the best suited welders for aluminium welding of components together and the answer is an Inverter AC DC tig welding machine. During the GTAW process the polarity of the arc changes and is either removing aluminium oxide from the surface or adding heat to the weld pool. The AC tig welding process is best for aluminium welders and is only slightly pipped by hybrid wave processes that include a DC component.
Hybrid wave welding equipment injects a small DC interlude between the AC welding cycle. When welding aluminium the AC arc is balanced between cleaning and penetrating with the percentages varying based on the operator’s choice. The DC component is 100% penetrating so the overall effect to the aluminium tig welding process is an additional heat input resulting in deeper penetration. The use of inverter welders makes this complicated process much simpler.
Suitability and tig welder choice are always best discussed with our expert staff. The choice you make will everlast and it must be correct. The sales team at Tokentools welding equipment supplies is always willing to assist our customers on making the right choice. Call us on 1300 881 991 today.
