The Parweld XTM 356i is the brand new, three phase inverter MIG welder. This Multi-process MIG Machine can also deliver Lift TIG and MMA, so you can get all your favourite processes in one system. This high-performance inverter is suitable for use with a 5kg (200mm) or 15kg (300mm) wire spool and puts out 350A of power. The XTM 356i MIG is also suitable for welding materials with ease using anywhere between 0.6 – 1.2mm MIG wire.



Infinite control of both volts (MIG Range: 15.5-31.5V) and wire feed speed allows the user to adjust parameters to achieve optimum settings for the perfect weld. LED digital display show all parameters in real time for quick, easy, and accurate adjustment of weld settings.  A settings chart inside the wire feed door show quick and easy reference voltage and wire feed settings for optimal set up.

Fitted with a set of quality 4 roll wire feed rollers, ensuring hassle free and smooth wire feed with even the most delicate MIG wire materials. A set of 0.8/1.0 V groove rollers comes included with the standard machine.

2T/4T control functions available. 2T is a simple press-on/lift-off button control, which keeps the current running when pressed down and cuts power when not. 4T is a system where, once the button is pressed, the arc will stay running until the button is pressed again, making it ideal for longer welding runs.

An industry-standard euro torch connection allows the use of all good quality MIG torches. P1 Package supplied with the Parweld XP200A 4 metre MIG torch.

Perfect for in the workshop the Parweld XTM 356i is supplied pre-built on a trolley, complete with a drawer and an integrated gas bottle shelf behind the machine.

The XTM 256I supports lift TIG functionality, with a connection for a switch plug and a gas connection.  Many machines with Lift TIG functionality do not have these features.  Gas is often controlled via a manual gas valve on the torch which can be fiddly and waste gas!  Press the trigger on the optional TIG torch to start pre flow and start the weld and finish the weld when releasing the button.



Parweld have designed this MIG inverter with ease-of-use in mind, and thanks to their synergic control, finding the optimal settings has never been easier. Synergic programming, as seen in the XTM 356i MIG Inverter, is a self-adjusting parameter set-up. Simply input your wire type and diameter, then select your amperage and the machine will adjust accordingly. It couldn’t be easier. Suitable for those still learning to weld or for the pros that want a simpler way of finding their optimum settings. This is the perfect beginner’s welding machine.  To fine tune the settings, a voltage trim is available to dial in the weld characteristics.
