Features and Advantages

  • MasterMIG 420W is a semi-automatic GMA (MIG/MAG) welding machine with separate and 4 drive rolls wire feeder which provides to work easily in areas distant from the power supply.
  • Suitable for high quality welding of constructional low-carbon steels and stainless steels.
  • Excellent arc caracteristics, sound weld beads and low spatter with 100% CO2 gas shielding.
  • 30 steps (3×10) welding voltage so as to adjust welding parameters conveniently.
  • Adjustable wire feed speed.
  • 2/4 trigger mode selection option.
  • Wire feed slow run (soft-arc) control function enables easier arc generation.
  • Equipped with thermal overload protection circuit.
  • Burnback time adjustment, gas flow (gas purge) control, cold wire inching functions.
  • Equipped with two digital meters to indicate welding current and welding voltage.
  • Water cooled.
  • Easy to use, highly reliable.
  • IP21S protection class.
  • Designed according to IEC 60974-1.
  • 2 years warranty (welding torch and cables excepted).
