  • $655.00


VIPER MIG182 is a inverter-based portable MIG welding machine with added MMA 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 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. MMA welding capability delivers easy electrode welding with high quality results, including cast Iron and stainless. Being 240v single phase gives great versatility. Ideal for DIY and home workshop. Designed and built to our specification.
