If you’re looking for a high-capacity TIG welder built for industrial-scale precision and performance, the STORM 500 AC/DC Pulse TIG is engineered to exceed expectations. Designed and manufactured in India, this versatile welding machine is equipped to handle stainless steel, copper, alloy steel, and other non-ferrous metals with power, consistency, and control.
The Storm 500 AC/DC is APS Welding’s highest-output TIG welder — rated 500 Amps at 60% duty cycle and 387 Amps at 100% continuous duty, built for heavy industrial TIG welding on stainless steel, aluminium, copper, carbon steel, and exotic alloys. Powered by a High-Frequency IGBT Soft Switching inverter, it delivers five welding processes in a single machine: MMA, DC TIG, AC TIG, DC Pulse TIG, and AC Pulse TIG.
With a wide input voltage of 330–500 VAC, pulse frequency control from 0.2–20 Hz, AC frequency up to 100 Hz, and a cleaning ratio of −40% to +40%, the Storm 500 is the definitive machine for shipbuilding, pressure vessel fabrication, power plants, and petrochemical pipelines. Manufactured at APS Welding’s ISO 9001:2015 certified facility in Valsad, Gujarat.

Nationwide service network, spare parts availability, and dedicated technical support for every Storm 500 unit deployed across India.
High-frequency soft switching reduces power consumption and heat generation compared to conventional transformer TIG machines — lower operating costs.
High precision welding for critical joints
Clean, strong, and defect‑free welds
Ideal for thin to thick material welding
Better control compared to conventional welding machines
Suitable for both manual & professional welding operations
