This welding machine is manufactured with advanced converter technology. With high-power component IGBT and PWM psychology, the inverter convert the DC voltage, which is rectified from input 50Hz/60Hz DC voltage, to high-frequency 20KHz DC voltage; as a consequence, the voltage is transformed and rectified.TIG functions Smooth arc and stable welding performance DC TIG function ideal for welding carbon steel, stainless steel, copper and other non-ferrous metals. TIG Welder 250A DC Electric Current Output; TIG welding on Stainless or Steel and Precise Welding of Thinner - gauge Materials. Easy ARC Start, Stable Welding Arc, Deep Weld Pool and Beautiful Welding Shape; Adjustable Hot Striking Arc Current which Can Greatly Improve the Arc-Starting Function; Suitable for Welding with Different Kinds of Acid or Basic Electrode. We also can provide 220V duel automatic input voltage shift; Air cooling, thermostatic protection, suitable for DIY. WELDING CURRENT : 10 - 250A. TIG TORCH (WP-17) × 1. EARTH CLAMP (300A) × 1. TIG COLLECT BODY × 3. Attention:There will be no plug due to plug differences between countries.
