Inverter DC arc welder allows welding stainless steel, alloy steel and carbon steel and other nonferrous metals.

The design and development of Inverter technology used in our welders allows for the high power output with its solid state MOS-FET (Metal Oxide Semi-conductor Field Effect Transistors). With high quality MOS-FET output components, these Welding units can function with a HF (high frequency) of 100kHz, thus reducing the size and weight of the main components (transformers).

The application of PWM (Pulse Width Modulation) technology enables the concentration and stability of the output current (AMPS) and with much more precise and convenient current control. The unique structural design enables the disassembly and maintenance of these units and maximizes EMI.

In comparison of traditional welding equipments, ZX7 has more advantages, as it is smaller, lighter in weight, higher in power exchange rate.
