TIG 400 ST

  • Digital current display for easy and intuitive monitoring and adjustment of welding parameters.

  • Automatic compensation for grid voltage fluctuations ensures stable arc and consistent weld quality even in unstable power environments common in India.

  • Advanced inverter technology allows multi-function use for argon arc (TIG) and manual arc (MMA) welding on various metals.

  • Easy arc start with HF arcing provides smooth, noise-free welding with minimal spatter and no magnetic deflection, producing clean weld seams.

  • Compact, lightweight, and energy-efficient design (14.8kg) improves portability and usability for workshops and field applications.

  • Suitable for welding stainless steel, carbon steel, copper, and other metals, broadening industrial and fabrication applicability.

  • Rated with a 60% duty cycle and wide output range (MMA 10-300A, TIG 10-400A) enabling continuous operation for heavy-duty welding projects.
