The single side spot welding machine belongs to one kind of resistance spot projection welding machine,it is composed of the machinery frame structure, welding transformer, control system, water-cooling welding cable and welding torch, etc. The main electrical circuit adopts the diode thyristor(SCR)contactless switch, to make sure the circuit switch time rapidly and accurately. The control system can adjust the welding time precisely. The welding repeatability and welding consistency are both very good,also maintenance is very easy.
