Closed-Head Orbital TIG Welding

TC-300

The TC-300 is a purpose-built automatic orbital TIG welding head for high-quality, filler-free butt welding of thin-wall pipes in all positions. A sealed gas chamber and advanced cooling system ensure superior weld protection and continuous operation. Ideal for industries that demand precision and repeatability — food & beverage, instrumentation, and nuclear power — the TC-300's patented self-centering fixture eliminates tack welding, delivering fast, repeatable welds on pipes, elbows, tees, and flanges.
