Model of inverter DC spot welding machine: IST-3000 intermediate frequency inverter DC resistance welding control power supply is composed of single-phase or three-phase alternating current to pulsating direct current through a rectifier circuit, which is converted into intermediate frequency square wave through an inverter circuit composed of power switching devices and connected to a transformer. After step-down, it is rectified into direct current with less pulsation and supplied to electrodes for welding the workpiece. Inverters usually use current feedback pulse width modulation to obtain stable constant current output. The intermediate frequency inverter spot welding machine has superior performance and is suitable for welding thin metal parts with high thermal conductivity and fine workpieces.

This is an IST inverter DC series spot welding power supply supplied by Shenzhen STE Technology Factory. This product is widely used in hardware processing and welding industries such as batteries, electronic accessories, metal sheets, wires, sensors, temperature control switches, etc. Stable welding performance, greatly improve the production efficiency of automatic spot welding, enterprises to improve the efficiency of welding power supply models.
