APS Welding (Advanced Power Sources Limited) manufactures heavy-duty IGBT inverter TIG welding machines engineered to meet rigorous international quality standards. Designed, tested, and built at our modern manufacturing plant in Valsad, Gujarat, India, our Gas Tungsten Arc Welding (GTAW) units deliver pristine arc stability, minimal heat distortion, and dependable heavy-industrial duty cycles.
TIG welding requires exact current regulation, smooth High-Frequency (HF) arc initiation, and clean gas shielding. Whether you are executing delicate stainless steel tube-to-tube joints in pharmaceutical equipment or heavy aluminium pressure vessel welds, APS TIG power sources deliver micro-processor-controlled precision.
Every unit incorporates comprehensive circuit protections including Over-Current (OC), Over-Temperature (OT), Under/Over Voltage (UV/OV), Voltage Reduction Device (VRD), and Single Phase (SP) missing phase detection. Built for rugged industrial environments, our 3-phase machines operate reliably across wide grid input fluctuations from 330V to 500V.
Explore our diverse lineup engineered for specific fabrication scales, material types, and operating conditions.
Practical, highly reliable, and compact TIG welding power sources featuring inbuilt HF start units. Ideal for field installation, maintenance repair, pipework, and sheet metal workshops.
Rugged, heavy-duty power sources built to perform under extreme ambient temperatures and continuous multi-shift fabrication cycles in shipyards, power plants, and structural yards.
Flagship digital TIG power sources featuring DIGICON technology. Fully programmable TIG parameters, Weld-O-Meter arc time recording, job memory, and password lock for strict code compliance.
Advanced AC/DC inverter TIG power sources specifically designed for welding aluminium alloys, magnesium, brass, and stainless steel. Includes square wave balance, adjustable AC frequency, and pulse parameters.
Maximize weld deposition rates, protect torch consumables, and achieve flawless weld cleaning with APS auxiliary systems.
Increase TIG production speed by 30%+ with our mechanized cold wire feeding unit. Fully synchronized with the TIG arc start cycle, it reduces manual welder skill dependence, eliminates filler rod stub waste, and ensures uniform weld profile quality.
Essential for high-amperage continuous TIG welding above 300A. Features a 50-liter coolant reservoir with built-in coolant flow rate sensors that interface directly with the power source to stop the arc if water circulation drops, protecting expensive water-cooled TIG torches.
Fast, eco-friendly post-weld passivation and cleaning for stainless steel TIG welds. Restores corrosion resistance and removes heat-tint discoloration instantaneously without toxic hydrofluoric pickling pastes.

Hygienic stainless steel piping and vessel fabrication requiring defect-free, smooth interior weld beads.
Critical root passes and tube-to-tubesheet joints meeting ASME Boiler & Pressure Vessel standards.
High-integrity aluminium and titanium structures welded using Storm AC/DC pulse systems.
High-pressure piping spools and cross-country alloy pipeline root pass construction.
Traceable digital parameter control using Apollo DIGICON units for defense equipment.
High-speed thin gauge stainless steel and aluminium exhaust manifold fabrication.
TIG (Gas Tungsten Arc Welding) machines provide high precision and clean, high-integrity welds on stainless steel, aluminium, titanium, copper and carbon steel. They are essential in pharmaceutical equipment, pressure vessels, aerospace, nuclear components and critical pipe welding.
AC (Alternating Current) is required for welding aluminium and magnesium because the reverse polarity cycle removes oxide layers while the straight polarity cycle penetrates the metal. DC (Direct Current) is dedicated to stainless steel, mild steel and copper.
Pulse TIG rapidly alternates between high peak current and lower background current. This controls heat input, minimizes sheet distortion, prevents burn-through on thin gauges, and delivers neat bead aesthetics.
The digital Cold Wire Feeder automatically feeds filler wire into the weld puddle in sync with the TIG cycle. It increases deposition efficiency by up to 30%, reduces operator fatigue, eliminates stub waste, and delivers consistent weld profiles.
APS 3-Phase TIG power sources feature ultra-wide input voltage protection operating smoothly from 330V to 500V. This safeguards internal IGBT electronics against generator surges and unstable grid power commonly found on remote jobsites.
