ARC-ZX7-400/500 Hand arc frequency converse rectifiers are our company’s patent product, adopting the electric device IPM intelligent power module of the newest generation as the frequency converse part.

IPM is short for intelligent power module, highly density of integration, lower cost, wide security work scope ,it has anti-over voltage, anti-under voltage, anti-over current, anti-over temperature and etc.

Apply IPM module as the switch part, so the welding machine is small volume, light weight, energy saving ,it is the fifth generation welding machine after SCR, BTR, VDMOS and IGBT

ARC-ZX7-400/500 DC Hand arc frequency converse rectifier can weld all kind of low carbide steel, alloy steel, steeless steel ,copper, copper alloy and cast iron,e quipped with argon arc welding torch,it can weld low carbide steel,alloy steel,steeless steel ,aluminum ,aluminium alloy,thin workpiece of copper,copper alloy and cast iron,it also can weld the bottom layer of the pipe and the remelting of the welding seam surface. it is an ideal welding equipment in power, metallurgy,chemical, petrochemical,boat,mine and communicating industry.

This equipment consists of six ZX7-400s, only one ZX7-400 or six ZX7-400 together can work at the same time,suitable for large industry and mining enterprise,easy to management.
