AC / DC Inverter TIG Welder

TIG / Argon Arc Welder

AC / DC inverter TIG welding machine using digital inverter control technology, providing the full set of characteristics needed for both DC TIG and AC TIG welding. All TIG and MMA parameters can be preset, stored and recalled before welding, so a qualified procedure is reproduced exactly shift after shift. The machine offers self-locking, non-self-locking and repeated non-self-locking state selection, and a gas-check function makes argon flow adjustment straightforward. Protection and indication functions are comprehensive. An interface for an optional foot controller and a dual-machine synchronous communication interface are provided. Applications Mainly for carbon steel, stainless steel, aluminium and aluminium alloys, copper and copper alloys, heat-resistant steel, titanium alloys, magnesium alloys and aluminium bronze. Widely used in aerospace, locomotives, shipbuilding, pressure vessels, air separation plant, heat exchangers, petrochemicals, substations, and the automotive, motorcycle and bicycle industries.

Key Features

AC and DC in one machine: AC for aluminium, DC for steel, covering all common materials
Adjustable AC cleaning width with square-wave output for a stable arc
Cathodic cleaning removes the aluminium oxide film for reliable fusion
DC mode gives a concentrated arc and deep penetration for stainless and carbon steel
Complete pre-flow and post-flow gas control plus full protection functions
All TIG and MMA parameters preset, stored and recalled before welding
Optional foot-control interface and dual-machine synchronous communication

Typical Applications

Aluminium vessels and heat exchangers
Stainless pressure vessels and pipe
Rail transit and aerospace aluminium components
Mould repair and precision part build-up

Selection & Setup Notes

AC/DC TIG is the "one machine for every material" choice: AC cathodic cleaning for aluminium, a concentrated DC arc for steel. If you only weld steel and mostly thin sheet, the DC pulsed model costs less.

Frequently Asked Questions

How much AC cleaning width should I use?

Increase it for heavy oxide or contamination, but too much accelerates tungsten wear and reduces penetration. Start mid-range for the thickness and surface condition, then trim.

Which tungsten for aluminium?

Zirconiated or pure tungsten, which holds a good ball under AC. Ceriated and lanthanated suit DC steel work better.

How thick an aluminium section can it weld?

It depends on current class and preheat; thick aluminium generally needs high current with preheat and multi-pass. Send us the duty details for assessment.
