WS5 series DC TIG IGBT inverter welding Power

WS5-400 welder is designed for two processes including GTAW with the high-voltage impulse and SMAW. Its perfect universal welding equipment for the easy practical operation and high arc stability. Main Features: IGBT inverter, using soft-switch technology which has inverting frequency of 20 kHz, es the good dynamic performance and .Using Current negative feedback control, to gain more stable welding current and excellent Anti-electricity voltage fluctuations.Design of the high-voltage impulse striking arc on TIG provides the good striking results even in the 50m welding cable. With the pre/post flow time, a better weld shielding is provided. The welding current upslope/downslope time adjuster complies with welding process. The machine has a long / short Weld conversion feature on TIG for labor intensity lessening .Designed for all SMAW rods. Easy to striking arc, stable arc, less spatters, perfect weld forming, and low noise. Presetting of welding current, high-adjusting accuracy. Small volume, light weight, high duty cycle, energy-efficient.
