- XNL-k Series
- Open-Type Orbital All-Position Welding Machine
This welding head is specifically designed for tube-to-tube TIG welding, suitable for carbon steel and stainless steel tube butt joints/tube flange fillet welds. It is suitable for fusion welding or wire-filling welding using an external XB50 head integrated wire feeder with AVC (arc voltage control) and OSC (oscillation control) functions. It is compatible with the XNL-M400 digital programmable welding power source, enabling precise orbital TIG welding for tube/tube welding with high repeatability. It is mainly used in the fields of chemical industry, food, medicine, engineering installation of boilers, military nuclear energy, and more.
Performance Features
