MasterMIG 501W

- MasterMIG 501W 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 (optionally gas cooled).
- Easy to use, highly reliable.
- IP21S protection class.
- Designed according to IEC 60974-1.
- 2 years warranty (welding torch and cables excepted).
