Capacitor spot and projection welder stores the electric energy in the condenser and discharges heavy low voltage current in an instant while penetrating the contact point of workpiece with centralized heavy current which generates heat of resistance for welding.

1.Vast Application:it is able to weld up to 3mm stainless steel and nonferrous metals like copper,aluminium and silver,which overco-mes difficulty of welding different metals like copper and aluminum etc

2.Firm and beautiful weld:firm welding ,no black on welding spot,no gringding needed,especially suitable for production of export products.

3.Save electricity and energy:It get low instantaneous power from the power network,thus of high power factor,uses only1/7-1/10 electricity as compared with that of the industry frequency welder at equivalent welding capacity ,therefore ,it is low cost.
