2.2 TIG welding
Tightly connect the air pipe with the air inlet of the welding machine rear plate；The air
1
supply path should include gas bottle, argon decompression flowmeter and air tube. The
connecting part of the air tube should be tied tightly with hose clamp to prevent leakage and air
entry.
Insert the gas-electric integration interface of the argon welding torch and the welding
2
torch switch into the corresponding position on the panel, and tighten it clockwise.
Connect the ground clamp to the positive pole socket.

electrode of the argon welding torch and the workpiece as 2-4mm, press the torch switch,
ignition arc, then it can work.
connect with work piece（"+"），cathode connect with TIG torch（"-"）。
