How do you make a simple spot welder with several 10000uF-250V capacitors?
Isn't it better to give professional jobs to professional people? Safety is the key!
Small 220V power transformer one, 300W or more, the bigger the better, the price is about 100 yuanRelay oneInching switch oneTwo barWelding ability1.5mm+1.5mm steel, aluminium, stainless steel plate
Buy a transformer 220V variable 380V or 220V isolation transformer, power 1KVA, SCR two, a charge, a discharge. A circuit that detects the charging voltage of the capacitor is needed to disconnect the charging silicon.Simple point is controllable, wow, you can use relays or contactor control, if not afraid of explosive capacitor risk, you can use time relay control charge and discharge.
