TOA Series Pipe Heads AVC&OSC

TOA Series Pipe Heads AVC&OSC

Open thick-Wall pipe to pipe weling expert-orbital welding head Suitable for pipe installation, wide range of welding with AVC tracking and OSC covering.

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.
