Notes

1. Gas flow for shield gas is 9-14L/min while at current of 100-200A and 14-18L/min at 200-300A. Tungsten elongation is 3-5mm and arc length is 1-3mm; Wind speed≤1.0M/s; Argon protection is recommended on the back of the welding area.

2. Welding linear power directly affects mechanical properties and crack resistance of welding metal during welding.

3. Strictly remove grease, moisture and other impurity on welding body.
