How to adjust argon arc welding when welding stainless steel coil and square steel?

2 The welding of plate and square steel is the same as 1, and the current between square steel and square steel is 120, and the air flow is constant, so the welding with wire is more firm.

The plates of 3 0 and 2 are welded on the iron angle steel, which is not easy to weld and the plates are too thin.

The black needle can be flush with the muzzle and can completely enter.

General gas stations are filled with large bottles. 13 pressure per bottle. The 8L model is only for backup and easy to carry, and the 40-50 model only needs to weld the sealing skeleton with rolled plate.

Welding angle steel and galvanized sheet is very troublesome. Just try it. Welding that kind of iron square steel is ok, but it is not strong.

I suggest you fill it up and try again.

If you really haven't learned it before, you can try to reduce the current, but the airflow can be kept constant or minimized, which can save a lot of argon.

If you don't understand anything, please ask me. May everything go well!
