Q: What is the cause of unreliable spot welding when the spot welder is in use? A: Firstly, the cause of poor power supply is excluded. Plug the machine power plug into the wall and make good contact with the primary socket; check the parameter setting and reset the electric pulse current and pulse value; adjust the welding pin pressure according to the thickness of the weldment; check whether there is any Oxidation layer or dirt is removed; check the soldering needle for oxidation and sanding with fine sandpaper. Q: When the spot welder is in use, what is the cause of the power supply circuit leakage switch action trip? A: When used, the AC pulse spot welding machine absorbs the energy of the grid instantaneously (milliseconds) on the power supply circuit, and its pulse spike current is large. The leakage protection switch or the air automatic switch with poor individual quality and poor anti-interference ability may cause errors. Action, when this happens, the welder can be replaced with another power supply line for trial use. If it is normal, the faulty switch can be replaced with good quality. Q:What is the spark of the welder during spot welding? A: The parameter adjustment is too large, the number of pulses is too much, or the contact of the soldering needle is poor.
