Unimig 350amp Compact Inverter MIG Welder


The UNIMIG 350K is an inverter-based multifunction MIG welding machine with added MMA and TIG function. The MIG function allows you to weld with both Gas Shielded and Gasless wire applications. Easy step-less adjustment of voltage and wire feed make for easy setting of welding parameters giving excellent, professional welding results.

Available on backorder


Spoolgun ready function that allows the simple connection of the PLSP240 Spoolgun, this is for the use of thin or softer wires that don’t have the column strength to feed through standard MIG torches, such as aluminium wire.

Added MMA welding capability delivers easy and high quality welding using electrodes, including cast Iron, stainless and low hydrogen.

Connection of the 26V TIG torch provides quality DC TIG with Lift Arc start for welding of steel, stainless steel and copper. The machine is industrial rated and of solid construction, large industrial wheels allows easy and smooth manoeuvrability. Ideal for general engineers, maintenance workshop, rural workshop and tafe colleges. Designed and built to our specification. Certified to – AS/NZ60974-1
