ZX7 series IGBT inverter DC manual welding machine is a new type of high-efficiency energy-saving DC welding machine. The promotion of the use of this replacement product has been valued by various countries. This kind of welding machine has a very high comprehensive index whether it is used for manual welding or automatic welding power supply. Due to its unique static characteristics and good dynamic characteristics, the welding machine has the following characteristics:

1. Dynamic response, reliable performance, stable welding arc and beautiful weld appearance.

4. Easy arc ignition, small splash and low noise can greatly improve the working environment of the operator. It is especially suitable for frequent moving welding of drilling platforms, petrochemicals, natural gas pipelines, docks, railways, bridges, mines, construction and equipment maintenance. In the case of machines, it is also suitable for welding processes that require high load continuation rates, such as batch products and large structures. Using advanced IGBT modules as inverter components and advanced circuit principles and control methods, the welding machine has excellent welding functions, providing reliable welding guarantee for boilers, high-pressure vessels, military and other industries requiring high-quality welding.
