Welding AC TOP 500

TOP 500, assigning:
Apparatuses intended for arc AC power when the electric welding
apparatus and principle of operation:.
Welders are wound on the toroidal transformer magnesium-toprovode. The windings are arranged in a special way to ensure optimum HEAT-dressing feature for welding mode. The transformer is placed in a metal case, the sides of the terminal blocks available for connection to a mains outlet and power cables. For the welding current are taps of the primary and secondary windings
