TUBE OD RANGE: 0.5–4.5″ / 12–119 mm
COOLING SYSTEM: Air or water cooled
FUNCTIONS: Orbital TIG welding by fusion or fusion + wire
SX122 Prefabrication Orbital Welding Machine (fusion + wire)
The SX122 prefabrication orbital welding machine delivers high-precision orbital TIG welding, supporting both fusion and fusion + wire processes. Easily adaptable, it can be converted into orbital cutting or beveling using the conversion kits.
Designed for all types of steel and exotic alloys, this automated system ensures consistent, high-quality tube assembly in a controlled workshop environment. Powered by the SAXX power source range, it guarantees reliable, repeatable welds while reducing on-site work, minimizing installation errors, and improving overall productivity.
