WSM-IGBT series inverter DC pulse argon arc welding machineDetailed product description：

The WSM series IGBT inverter DC pulse argon arc welding machine uses IGBT as the switching element in the inverter DC pulse argon arc welding machine. Firstly, the 50/60Hz power frequency input voltage is rectified and filtered into a DC voltage, which is then converted into a high-frequency AC voltage through a power electronic switch, stepped down by a transformer, and finally rectified and filtered into a DC welding voltage suitable for welding process requirements. Control and regulate the output current through pulse width modulation (PWM) technology. Due to the use of switch power inverter technology, the weight and volume of the welding machine have been significantly reduced, and the efficiency has been improved. This series of welding machines is a DC pulse argon arc welding machine, which can also be used as a DC welding rod arc welding machine and a DC argon arc welding machine. One machine is versatile. When doing argon arc welding, high-frequency oscillation is used for arc initiation, which is reliable and stable.
