2.Because of the instant welding large current, rated current of tripping device of the leakage protection switch should be up to 40-63A.Lower than 40A will cause tripping.
3.Please set the pressure adjuster to the right parameter to avoid welding effect in not good.
4. Please keep the surface of welding pins clean and wipe off oxide with sand paper.
5.Please keep the welding pin in sharp shape.
6. Please do not worry about the lighting in flash. Spot welder is a high power machine and discharging high current instantaneously.Because this moment is in 20ms and it is normal.
