TIG WELDING

Precision TIG Welding Solutions Built for Industrial Performance

The SigmaWeld SW Series TIG welding machines combine stable arc performance, accurate current control, and rugged construction. Designed for continuous industrial use, these machines ensure clean welds and dependable results across demanding fabrication environments.

 

Features for Precision TIG Welding

SigmaWeld TIG welding machines are engineered with advanced inverter technology to deliver stable arc performance and precise control. Designed for industrial reliability, they ensure consistent weld quality across demanding applications

Constant Current Output

Delivers stable welding output even with mains voltage fluctuations up to ±15% and operates reliably on generator power with balanced load.

 

Integrated Water Cooling Interlock

Compatible with SigmaWeld Water Cooling System featuring stainless steel tank and forced air cooling. Intelligent interlocking ensures water flow only during GTAW operation, preventing torch damage.

 

Smart & Efficient Operation

Automatic gas cut-off if welding does not start, preventing shielding gas wastage. Instant shutdown of current and voltage if tungsten contacts the job, avoiding electrode defects.

 

Advanced Protection & Safety

Built-in protections for over-voltage, under-voltage, thermal overload, output short circuit, and IGBT peak current locking for enhanced equipment life and operator safety.

 

Automation & Remote Control Ready

Supports foot pedal current control and easy integration with automation systems, robots, AVCs, weaving units, and cold wire feeders for higher productivity and weld quality.
