Spot welder power supply hint
All the pulse spot welder use power supply circuit to instant offer millisecond pulsed high current, by machine pulse isolation transformer conversion. In the end, high energy is applied to the welding output to achieve the purpose of reliable welding. And the following two reasons will affect the normal work or welding effect. Please attach importance.
1.When starting machine or during spot welding,the power line leakage switch off
	When starting machine or during spot welding, the pulse current muet be absorbed from the circuit. If the power supply line poor anti-jamming capability. Leakage switch will occur in the wrong action. That need replace a strong anti-jamming capability or replace 63A leakage protection switch. That can also change another power supply line to solve the problem.
2. Poor welding
A. Connect the unit from the wall outlet must be firmly and sure good contact. Don't contact from platoon insert, otherwise that can't supply transient high current pulse when spot welding.
B. Pay attention to clean the surface of work piece, prevent the oxidation or fouling of the work piece use for welding, otherwise that will have false welding.
