Overview
The VIPER 140 is a new generation, low cost 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 al-
lowing easy welding with electrodes producing high quality welds including cast Iron, stainless steel and low hydrogen. The VIPER 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 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 unique 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.
The VIPER 140 is an exceptional machine for the price and is suitable for a wide range of applications including light fabrication and
farming. The VIPER 140 offers great portability with the power to get the job done and with the convenience of being fitted with a 10 amp
domestic plug. Manufactured in compliance to AS/NZ60974.1.
