The Viper Arc Series is Uni-Mig's answer to the cheap low-quality DIY-level Inverter welders that have flooded the Australian market over the past decade. The Viper Arc is competitive on price with any light-weight DC TIG-Arc Inverter on the market. But importantly this machine is backed by one of Australia's leading welding suppliers, UniMig, meaning the Viper Arc is a high quality product back by a company with an Australia-wide network of service agents and a proven commitment and reputation for after sales service built over 40 years. The machine is backed by 12 months warranty with 6 months bonus warranty if you register online.

This machine is as reliable and robust as you would expect a machine bearing the UNIMIG name to be and it used the latest IGBT Inverter technology. The DC Arc 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 ARCLITE 140 is also equipped with DC Scratch Start TIG capability and connection of the 17V TIG torch allows DC TIG welding of steel, stainless steel, bronze and copper. The machine is extremely lightweight and practical for welder's who require portability. It also has the advantage of being fitted with a 10amp plug as standard.

The unique electronic design structure and air channel design in this machine speeds up the heat disapation of the power device improving the duty cycle of the machine. The air channel design also effectively reduces dust ingestion by the fan, dust build up and absorbtion by the electronic circuits and power device is minmised thereby improving the reliability of the machine. Manufactured in compliance to AS/NZ60974.1.
