ARC-400S/500S/500SK IGBT DC MMA Welding Machine

ARC-400S/500S/500SK IGBT DC MMA Welding Machine

The IGBT DC MMA welding machine 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.
