Performance
Adopt advanced soft swich inverting technology, take the imported IGBT and micro-crystalline magnetic core focus fittings
A high load duration rate; striking arc current and current push adiustment function are equipped
Bear voltage fluctuation automatic compensation function, stable electric arc, evenm olten pool, little splash and beautiful welding line.
The circuit board adopts imported insulating resin QC glue and the vacuity sealed design can prevent dust.
The air blower adopts isolated structure to prevent rain water,With energy-saving design, if it can not do arc start at the interval of 5 seconds, it will cut off the power of the main circuit to ensure safety and reliability

Functions
It is applied very well in the work site of 660V and 380V dual-purpose power operations in mines and coal mine undergroung
Applincable for the welding for carbon steel, alloy steel, cast iron, stainless steel, copper and alloy, When equipped with contact argon arc Welding gun the machine can be used in contact argon arc welding
