ARC-400S/500SK Arc Welder

The ARC-400S/500SK arc welder is compact, lightweight and portable. Designed with reliability, stability and safety in mind, it provides many protection functions. For instance, it has automatic undervoltage, overcurrent, overheat, overload and phase lack protection functions. The VRD function also helps ensure operator safety. In addition, the welder has good anti interference ability, which effectively protects the internal circuit and components, resulting in better stability. What's more, the electro magnetic compatibility (EMC) function and grid filtering ability ensure reduced power supply contamination.

Our ARC-400S/500SK arc welders are suitable for both civil and industrial use. They are widely used in the petroleum, chemical, metallurgy, shipbuilding, boilers, pressure vessels, pipes, vehicles, aerospace, and many other industries.
