The welding head is a special welding head designed for TIG welding of inner bore tubes and tube sheets. The welding materials can be carbon steel, stainless steel, etc., and the inner hole diameter of the tube sheet is ≥ Φ25mm; according to the needs of the welding process, self-melting, wire filling or first welding can be selected. Filling wire after self-fusing, etc. It can be used together with iOrbital5000 programmable welding power source, which can precisely realize all-position TIG inner hole welding, with high reproducibility of welding results and ideal welding results. It is mainly used for automatic welding of special tube sheet forms in boilers, heat exchangers, electric power construction, chemical industry and other industries.

The inner hole is added with wire to meet various process requirements;

The drive adopts imported hollow cup DC servo motor, which is stepless speed regulation within the speed range. All water, electricity and gas tubes and lines are free from entanglement;

With automatic arc length control function, this function can also be turned off to manually adjust the arc length;

Adopt the structure of a special water-cooled TIG welding torch;

Wire feeding without winding, comes with an integrated wire feeder, which can hold a 1.0kg wire reel.
