Hwashi experts introduce the principle and application of intermediate frequency inverter spot welder

The medium frequency inverter DC spot welder is a device that converts three-phase AC rectifier into pulsation DC, and then converts it into medium frequency square wave through an inverter circuit composed of power switching devices, which is connected to the transformer Buck DC resistance welding equipment for welding workpieces, rectifier into a small pulsating DC power supply electrode, is one of the most advanced resistance welding methods today.

The medium frequency inverter DC spot welder can be used for spot and multi-spot welding of ordinary low-carbon steel plates, stainless steel plates, galvanized plates, aluminum plates, wire and high-strength steels. Thermoformed steel in the automotive industry. Spot and nut projection welding in the high and low voltage electrical industry, as well as resistance brazing and spot welding of copper wires, brazing of silver and copper plates, and composite silver spot welding.
