Tube dia Range:Φ159-325mm
This automatic tube welding machine comprises an OBT-315 TIG welding power source and an OTH-130 open welding head, suitable for medium-wall carbon steel and stainless steel pipe welding. Its compact structure is easy to use on site, delivering good weld surface quality and fast welding speed.
Automatic all position TIG pipe to pipe welding with/without wire feeding
Compact structure design, stable rotation with small rotating inertia
Oscillation, multi-passes welding process
Suitable for connection of tube to tube, tube to flange, tube to elbow, tube to valve
Water circuit cooling, achieving long time working
This machine is modular in design, compact in design and compact in structure.
The main components are aluminum structure and stepless adjustable clamp to fix the pipe diameter.
