TIG 400 IJ Precision Welder

High-Power DC Output: Delivers a smooth and stable 20-400A for both TIG and MMA welding. Water-Cooled System: Includes an integrated cooler and 4m water-cooled torch for continuous, high-amperage welding and superior torch life. High-Frequency (HF) Start: Ensures a premium, non-contact arc ignition to prevent weld contamination and tungsten inclusions. Heavy-Duty Duty Cycle: A robust 60% duty cycle at 400A for maximum productivity on industrial jobs. Advanced IGBT Technology: The Single IGBT Module provides excellent arc stability and reliable performance. Weld Protection: Features adjustable Post Gas Flow (1-25 sec) to protect the cooling weld puddle and tungsten from oxidation. Dual Process: Easily switch between precision TIG welding and heavy-duty MMA (Stick) welding.
