Condenser discharge spot 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.
·Application:
It is able to weld up thick to 3mm stainless steel and nonferrous metals like copper, aluminum and silver, which overcomes the difficulty of welding different metals like copper and aluminum, etc.
·Firm and beautiful weld:
Firm welding, no black on welding spot, no grinding needed, especially suitable for production of ex- port products and parts.
·Save electricity and energy:
It gets low instantaneous power from the power network, thus of high power factor, uses only 1/7-1/10 electricity as compared with that of the industry frequency welder at equivalent welding capacity, therefore, it is of low cost.
