My spot welding is 0.4 mm iron net, in the process of use, always not scheduled trip, do not know what is the matter, please master advice.
The air switch shelter or your machine leakage, may be the largest air switch capacity is small, try to change the point
You should use the welding machine current is too large, and you use the switch, rated current is less than the current of the welder, change a larger switch will be good.
When there is an insulating substance between the two electrodes, the through welding will surely trip. (verified on site)
