1. Welding torch is pneumatically moved in up-down direction. Welding torch 

can be adjusted up and down, side to side and angled turn. The body of 

welding torch is ceramic. 

2. Japan OMRON PLC is 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.
