1 TIG/MMA Inverter Display Welding Equipment
2 Reduced size and weight
3 Highly effective and energy saving
TIG/MMA Inverter Display Welding Equipment WS-250(IGBT)

1. With 2-stroke inverter frequency regulation,welder can set an appropriate setting according to
usage and technology;
2. With the most advanced imported IGBT module as the core, inverter frequency can reach to
20KHz;
3.Unique water cooling design inside welding machine makes higher stability of IGBT;
4.Additional EMC(electromagnetic compatibility) circuit largely decreases electromagnetic pollution
to electricity gird;
5.Waterproof, dustproof and windproof design significantly improves the stability and duty cycle of
electronic components inside welding machine;
6.Mainly applicable to fine welding of aluminium, magnesium and their alloy, stainless steel, alloy
steel, various steels,copper alloy, titanium alloy and so on;
7.Compatible with manual operation and applicable to acid welding rod, low-hydrogen alkaline
welding rode,fibrin welding rob,heatproof steel welding rod and others.
