1. There are total 12pcs welding torch for welding circumferential seam. Welding torch can be adjusted up and down, side to side and angled turn. They maximize throughout, and welding deformation can be reduced significantly.

2.Japan OMRON PLC and torch screen are used to control the whole machine. With the help of touch man-machine interface, welding mode and specification can be preset,stored and retrieved. There will be fault alarm and indication during welding process, such as stuck wire, blocked wire, etc.

3.Push-type wire feeder works stably. Machine is with high welding voltage and slow wire feeding performance, which guarantees reliable arc igniting. Machine is also with low welding voltage and low welding current for filling crater.

4.Easy clamping and releasing rotary chuck.

5.Pipe will be fed into welding stage manually/automatic.

6.Brass/copper block as the conductive device (electricconduction) which directly connects with welding source. It is a basic security design.
