1. This equipment is all position tungsten argon arc welding, the welding point on the pipe, welding torch along the pipe welding way rotating a week, including flat welding welding up/down welding and overhead welding four different force different position because of the molten pool in different position, need to have different heat input, need to set the peak current of the different values and the process parameters such as electric arc voltage, current, are available on OBT-315 type integration control power supply man-machine interface to set is complete;

2. Single-sided welding and double-sided molding; the inner parts of stainless steel pipe shall be filled with protective gas (argon or other protective gas), the argon flow rate is 0.5-8L /Min, and the argon protection flow rate of welding gun nozzle is 8-15L/Min.

3. The equipment can be wired or welded by self-fusion. Customers can select and match according to the process requirements of pipe fitting and adopt wire welding
