Unimig 250amp Compact Inverter MIG Welder


The UNIMIG 250K 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 stepless adjustment of voltage and wire feed make for easy setting of welding parameters giving excellent, professional welding results. Wire inch gives easy feeding of the wire during set up without gas wastage and the Burn Back adjustment leaves the wire out ready for the next weld. An additional feature is the Spoolgun ready function that allows the simple connection of the PLSP240 Spoolgun 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. Being 240v single phase gives great portability, providing more flexible use for site and workshop locations. Ideal for general engineers, maintenance workshop and rural workshops. Designed and built to our specification. Certified to – AS/NZ60974-1
