Professional TIG welding system with automatic wire feeding capability for industrial pipe welding applications. Designed for carbon steel, stainless steel, and titanium alloy tubes with diameters from 63mm to 168mm.

This equipment features all-position tungsten argon arc welding with rotating welding torch technology. The system handles flat welding, up/down welding, and overhead welding positions with precision heat input control through peak current and arc voltage adjustments.

• Tube out of roundness ≤5%
• No welding bevel with plain ends; perpendicularity ±0.5°
• Tube surface must be flat, smooth, rust-free, burr-free, and cleaned with ethanol
• Complete joint alignment between two tube welding surfaces
• Stainless steel tubes require internal argon gas filling for one-side welding

• Automatic all-position TIG pipe welding with/without wire feeding
• Compact structure design with stable rotation and small rotating inertia
• Oscillation and multi-passes welding process capability
• Suitable for tube-to-tube, tube-to-flange, tube-to-elbow, and tube-to-valve connections
• Water circuit cooling system for extended operation periods
• Modular aluminum structure with stepless adjustable clamp
• Gapless gear transmission with automatic AVC control
