TOA Series Pipe Heads AVC&OSC

This welding head is special designed for pipe to pipe TIG welding, suitable for carbon steel, stainless steel pipe to pipe connection, mainly for wire feeding or self-fusion, option of TB150 integrated wire feeder and HWT10 external wire feeder with AVC & OSC function.
Support equipment: i-Arc400 Programmable Orbital Welding Power Source.
Application: chemical, food, medicine, engineering installation, boiler, military, nuclear and so on.

>> Suitable for medium wall thickness carbon steel, stainless steel material pipe welding
>> Suitable for connection of tube to tube, tube to flange, tube to elbow, tube to valve and so on
>> Automatic all position TIG pipe to pipe welding with/without wire feeding
>> Compact structure design, stable rotation with small rotating inertia
>> Water circuit cooling, achieving long time working
>> Oscillation, multi-passes welding process
>> Optional of external/integrated wire feeder.
