inverter automatic submerged arc welding machine

● The welding power adopts the IGBT soft-switching inversion technology, which ensures the high stability of the welding current when the network voltage fluctuates or the arc length changes. The arc has a strong ability in self-adjusting.
● It has the function of adjustment of the arc-starting current. It may adjust the arc-starting current according to the technical requirement for the welding, so the success rate of arc starting is greatly improved.
● It has the function of adjustment of the thrust current, which ensures the formation of weld, makes it convenient for the adjustment of the weld penetration. Thus the adaptability of the welding power to the welding technology is improved.
● Compatible with the manual arc-welding; so it may be used in carbon arc air gouging, manual arc welding etc.
This series of welding machines have a wide range of adjustment to the current. The minimum current is less than or equal to 60 A;
● Light in weight, small in volume and easy to be removed.
● With high efficiency and high power factor, it is an energy-efficient equipment.
