The VIPER 140 is a new generation welding machine produced using the latest in IGBT inverter technology. Designed to meet the needs of the price-conscious non-commercial user without compromising on quality, this machine is as reliable and robust as you would expect a machine bearing the UNIMIG name to be. The DC MMA welding function delivers a smooth and incredibly stable arc allowing easy welding with electrodes producing high-quality welds including cast Iron, stainless steel and low hydrogen. The VIPER 140 is also equipped with Scratch Start DC TIG capability and the connection of the 17V TIG torch allows DC TIG welding of steel, stainless steel, bronze and copper. The unique electronic design structure and air channel design in this machine speed up the heat dissipation improving the duty cycle of the machine.
