Twin Wire Gas Shielded Welder and Arc-submerging Welder


Twin Wire Gas Shielded Welder and Arc-submerging Welder

1.     Function

Twin Wire Gas Shielded Welder consists of a gantry automatic welding carriage and two independent power supplies, which can work independently or cooperatively for semi-automatic welding and automatic welding. It can realize MIG/MAG, TIG, flat wire MIG/MAG, TANDEM twin wire welding, SMAW, and many other technological process.

Twin Wire Arc-submerging Welder consists of the gantry automatic welding carriage, wire feeding mechanism,one DC power supply and one AC power supply.These two power supplies can work independently or cooperatively, and the arc can form their own molten pool,with DC molten pool in front and AC molten pool behind—forming a coverage layer.This mechanism has a high effeciency for welding, which greatly improves the welding speed and quality of medium-thickness metal plates. DC power supply can provide precise control over high-current TIG welding, FCAW, arc-submerging welding and carbon arc gouging for a carbon rod with a diameter of 5/8 inch.
