No-Filler Orbital TIG Welding
The TC-300 and TC-400 are precision-engineered orbital welding heads designed for high-quality, no-filler TIG welding of pipes and fittings in all positions. Featuring a gas-sealed chamber and integrated water cooling, these systems deliver superior weld protection and repeatability — ideal for food & beverage, nuclear power and instrumentation industries. The patented self-centering fixture ensures precise alignment without tack welding, streamlining on-site installation and production workflows.
Key Features
Full-position welding for pipes, elbows, flanges and tees.
Compatible with thin-wall stainless steel, titanium, titanium alloys and carbon steel.
Aluminum construction ensures durability and portability.
Sealed chamber with argon protection for oxidation-free welds.
Eliminates manual alignment for faster setup.
Water-cooled design supports prolonged welding cycles.
Integrated handle buttons simplify operation.
