Medium Frequeny Technology
Medium-frequency technology improves the performance of spot and projection welding machines, seam welders, as well as for welding transformers and controls. Further, in many cases, medium-frequency units can be installed on existing welding machines, completely upgrading them with a limited investment.
features
It is a resistance welding process in which the welding transformer is powered by an inverter that increases the mains frequency from 50 to 1,000 Hz. On the secondary of the transformer the current is rectified through a diodes group. The primary power absorption is three-phase with a balanced load. The result is a welding system with performance superior to any other.
