DBT 280 Inverter Spot Welding Machine


PLC inverter spot welder


240KVA inverter spot welder

Product Description

80-450KVA Pneumatic Spot Welding Machine and Projection Welding Machine In Auto Parts Industry

High power medium frequency inverter DC spot (Projection)welding machine


Product highlights: balanced three-phase power input, small impact of DC output on user power grid, energy saving, stable current, high welding quality.

MF DC Inverter Spot Welder is a set of advanced welding equipment. The welding transformer is in small size but the outout energy is large. Three-phase AC will be converted into DC after being rectified. Then the DC will be converted into medium frequency 1000HZ square wave to be connected to primary welding transformer through the inverter circuit which is composed of IGBT. The MF square wave will become small pulse DC to the electrode for welding work piece through the depressurization and recitifying process in the welding transformer. The Inverter will adjust the duty ratio of IGBT through the feedback of secondary current so as to achieve constant current of the welding process.
