Advanced Imported IGBT Inverter technology, high efficiency, energy saving, and environmental protection. Super strong ability of the anti-fluctuating of power supply voltage. Under 280-460V, the welding power source will have an output current and can weld. Suitable for stable welding with extended cables up to 150 meters. With a five-proof design, it ensures working stability and reliable when kinds of harsh welding circumstances. High-level water-resistant design can be fully dipped into the water under switch-off conditions. Using PWM control technology and constant current output control can be exactly controlled. Auto protection functions to prevent over-current and over-heating making the machine safe and reliable. Applicable to acidic, alkaline, high-strength electrode. Intelligent fans add comprehensive protection. Ultra-low output function (VRD), meets EU standards to prevent electric shock.
