Silicon Carbide Technology
Powered by next generation SiC MOSFET hardware, the machine runs cooler, responds faster and delivers a noticeably steadier arc. Expect improved reliability, tighter arc control and cleaner overall weld quality compared to traditional IGBT systems.

Not All Pulse Machines Are Equal
Less spatter. Lower heat. Smoother results. Streamline your welds with the single and double pulse functions.
A single pulse weld alternates between a peak and base current, which works to minimise the amount of heat input without compromising on any of the penetration. The addition of a base current and reduction in heat means it's perfect for softer materials like aluminium. Pulse welding is also done by spray transfer, eliminating spatter and cutting your post-weld clean-up time.
A double pulse weld alternates between a peak current and two base currents, reducing the heat input of the weld even further than single pulse, while still maintaining all of the benefits. Because of the faster freezing puddle, your double pulse welds come out looking just like a stack of dimes. You get the aesthetics of a TIG weld with all the speed of spray MIG.
MIG Smart-Set
Ready to weld with the press of a few buttons. Simply select your joint type, filler wire, gas mixture, and wire diameter, and the machine will choose the ideal settings. If it’s a little off, you can make manual adjustments to finetune every weld.
Ultimate TIG Welding
Weld every kind of metal. With the ability to run on an Alternating Current (AC) you’re able to weld aluminium as effortlessly as mild and stainless steels on a Direct Current (DC).
TIG Smart-Set
Starting a weld has never been faster with the class-leading synergic TIG. Choose your material, joint type, tungsten diameter, plate thickness, and gas mixture, and you’re off and running. If it’s not quite right, you can tweak the parameters to perfection.
Advanced TIG Programs
The independent amplitude lets you adjust the amperage in both the EP and EN parts of the AC cycle, letting you completely customise the amount of heat directed to the workpiece and the tungsten.
Speed up the formation of the weld puddle by applying a synergic pulse program to the beginning of the weld. The initial pulse works to melt the joint edges faster, for quicker puddle formation compared to a standard arc start.
Steady Arc adjusts the welding current based on the arc voltage. When the voltage goes down, the amperage will go up, and vice versa, to give a consistent weld puddle, a sharper arc and a constant heat input. Weld speeds can be increased with no fluctuations in the weld current.
TackPlus is a tack welding program used to create evenly spaced and sized fusion tack welds along a joint with minimal heat input.
Get the perfect tungsten shape for your aluminium welds every time with just the click of the trigger. Turn the cap shaping feature on, press the torch trigger, and the machine will prep the optimal tungsten shape for your aluminium welds.
AC and DC Waveform Control
With 12 waveform options available, including AC and DC combinations, you can tailor arc characteristics for different materials, joint types and performance needs.
Automatic Polarity Switching
Change weld modes without manual cable swapping. Press the torch trigger and the machine switches to the required polarity automatically, making setup faster and reducing downtime between processes.
Line Resistance Detection
The machine measures and compensates for resistance in your welding cables, ensuring consistent voltage at the arc regardless of cable length or setup changes. This delivers a steadier arc, cleaner bead formation and reduced spatter, especially when working with long extension leads.
Full Size Spool Compatibility
The machine accepts both D200 and D300 spools, giving you the flexibility to run larger 15 kg mild steel reels or 7 kg aluminium reels. Fewer spool changes and longer uninterrupted weld time.
Accessories
Ready for any kind of welding you've got planned, connect a complete range of MIG, TIG or MMA accessories to your welder.
Get the ultimate flexibility. The addition of a separate wire feeder means you can detach the wire feeder from the main power source, giving you an extra 10m of manoeuvrability. Adding a SWF also allows you to run two wires from the machine at the same time.
Maximise your flexibility, portability, manoeuvrability with the T40 Welding Trolley.
Maximise your TIG welding performance, especially at high amperages. When combined with the T3W Water-Cooled TIG Torch, which uses Bi-Flow™ Technology, you get greater performance from the TIG torch.
Enjoy greater control and precision with our optional foot control accessory. This handy feature allows you to easily adjust your TIG amperage on the fly, without interrupting your torch movement. Wireless and wired options available.
Achieve smooth and steady wire feeding, especially when using softer wires such as aluminium. With a 'Pull' motor built into the torch, the wire can be fed over a greater distance, granting you the freedom to move and manoeuvre with ease while MIG welding.
Digital 4 Geared Wire Feed System
The digital controlled four geared drive delivers strong, even pressure to the wire for smooth and reliable feeding. It handles soft wires like aluminium with ease, reducing birdnesting and removing the need for a spool gun. This gives you cleaner feeding and a steadier arc across all torch lengths.
Power Factor Correction (PFC)
Get the most out of your machine. The PFC maximises the electrical efficiency of the machine and automatically compensates for any voltage fluctuations, so you get more output power and the internal components last longer.
Smart Fan Technology
The fan runs only when needed, reducing noise, cutting power use and limiting the dust drawn into the machine. This keeps internal components cleaner and helps extend the overall life of the unit.
Advanced MMA Features
Advanced MMA features are designed for improving weld quality and ease of use.
Revolutionary pulse stick reduces spatter, improves heat control and makes for easier slag removal, as well as improves the speed and efficiency of vertical up welds without sacrificing any root fusion.
The Arc Force feature helps to keep the arc stabilised throughout the weld, by increasing or decreasing the peak current to compensate for your arc length, preventing the arc from cutting out or the electrode from sticking.
The adjustable hot start is designed to help with striking an arc. The hot start temporarily boosts the output current at the start, making striking an arc, even with difficult electrodes, much easier. You get smoother arc starts, improving the quality of your weld.
The Anti Stick feature, which is always on, prevents your electrode from sticking to your workpiece. When the machine detects sticking, the current will drop significantly, so the electrode can be removed.
Additional Features
Job Memory
The job memory function allows you to enter and store weld parameter settings. Weld parameters can be further adjusted and stored as required. A total of 100 jobs can be memorised and stored for recall.
Mixed AC/DC
Experience the best of both worlds. Mixed AC/DC combines the efficiency of AC and the penetration of DC- TIG in one weld. With it, you get faster welding speeds, better penetration, a faster weld puddle on cold workpieces, and you can weld on thicker materials.
Low Amp TIG With Stable Arc
Maintain a stable arc even when TIG welding as low as 3A. The new and improved SiC MOSFET technology means you can hold a steady arc no matter how low your amperage.
Higher Pulse Frequency in AC & DC
With a pulse frequency as high as 999 pulses per second in both AC and DC TIG, you can get as many pulses as you need for any scenario.
Inductance Control
Take complete control of your arc with the inductance settings. By changing the frequency of your short circuit MIG welds with the Inductance controls, you can choose your preferred arc characteristics on every weld.
Burnback Adjustment
Stop your wire from ever fusing with your weld or your contact tips again. Tune your burnback control to suit how much wire you want to remain sticking out from your torch when you finish a weld.
Robotic Connection
The robot connection lets you integrate a robotic arm into your workflow, which can improve the precision, consistency, and efficiency across welding tasks. It allows for automated, repeatable welds, reducing human error and improving productivity.
Dual Gas Inputs
Set up for MIG and TIG at the same time. With dual gas inputs for both weld types, you won’t need to swap your gas when you swap torches. The quick connect inputs also make replacing your gas bottle as simple as unplugging and plugging in.
Generator Compatible
Take it anywhere. Connect the machine to a generator and use it wherever, whenever you need it. We recommend 12kVA for this machine.
