The MIG250SWF is an inverter-based MIG welding machine with added MMA and DC TIG function. The machine is equipped with a separate 4 roll gear driven wire feeder and 10m interconnecting cables. The MIG function allows you to weld with both Gas and Gasless wire applications. Adjustment of Voltage & Wire Feed at the feeder makes for easy setting of welding parameters and gives the convenience of remote adjustment from the power source. Crater Current setting delivers perfect finishing of the weld, the electronic Inductance offers fine adjustment of the arc characteristic and Burn Back adjustment leaves the wire out ready for the next weld. Wire Inch and Gas Check provides set up of wire feed and gas setting without wastage of wire or gas. 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 lift arc DC TIG welding of steel, stainless steel and copper. 240v single phase gives great portability, providing more flexible use for site and home workshop locations. Ideal for general engineers, maintenance workshop and rural workshops.
Designed and built to our specification. Certified to – AS/NZ60974-1
