1mm galvanized square pipe argon arc welding pressure adjustment?

For 1mm galvanized square pipe, adjust the argon arc welding pressure to 2mm. Hold down the switch and watch the steel ball float. It is enough to float about 2mm. If the welding speed is slow, the current will be small, and if it continues to burn, it will be deformed at high temperature. If instantaneous welding requires a large current, it is not a standard material now, and the actual value of 1.0mm is less than 0.4 mm. You can check it with a caliper, and remember to send welding wire when welding.
