The MIG500SWF is an inverter-based MIG welding machine with added MMA and TIG function. This is an industrial machine equipped with a separate 4 roll gear driven wire feeder and 10m interconnecting cables. The MIG function allows you to weld with Solid wires, Fluxcored Gas and Gasless wires. 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.  Ideal for heavy and structural
welding applications, general engineers, maintenance workshop, rural workshops.
Designed and built to our specification. Certified to – AS/NZ60974-1
