Capacitive Discharge Welder ESW 100

Our capacitor discharge welders (CD welders) leverage advanced electronic voltage elevation and constant-current charging circuit technology to store electrical energy in capacitors. This stored energy is discharged instantaneously to the workpiece via a pressure mechanism, melting the contact metal

Details

Capacitive Discharge Welder ESW 100

The stored energy welding power supply – commonly called a Capacitive Discharge Welder or CD Welder – extracts energy from the power line over a period of time and stores it in welding capacitors. Thus, the effective weld energy is independent of line voltage fluctuations. This stored energy is rapidly discharged through a pulse transformer producing a flow of electrical current through the welding head and workpieces.

capacitor discharge metal welding

Capacitive discharge power supplies are rated in accordance with the amount of energy they store and the welding speed. The energy stored, expressed in watt-seconds (joules), is the product of one-half the capacitance of the capacitor bank and the square of the applied voltage. The energy delivered to the electrodes is considerably less than this value because of losses in the primary and secondary circuits.
