Standard resistance welding machine

DBZ desktop traceless medium frequency resistance spot welding machine

DBZ Desktop Traceless Intermediate Frequency Inverter Pneumatic Resistance Spot Welding Machine Projection Welding Machine is a three-phase alternating current that is rectified into DC, and then passed through an inverter circuit composed of IGBT power devices, into an intermediate frequency 1000-4000HZ AC square wave output. After being stepped down by a transformer, it is rectified into DC and supplied to the electrode for welding the workpiece. Current feedback and pulse width modulation (PWM) are used to obtain stable current output.It is one of the cutting-edge resistance welding methods today. With a universal rotating arm and a desktop electrode plate, it is mainly used for large sheet metal parts such as doors, iron cabinets, boxes, and chassis that are difficult to move. The surface of the welding workpiece is smooth and has no welding pits. It can be sprayed directly without grinding, saving labor, time and high efficiency.
