TUBE OD RANGE: 5.563″–12.750″ (141–328 mm)
COOLING SYSTEM: Air or water cooled
FUNCTIONS: Orbital TIG welding by fusion or fusion + wire
SX322 Prefabrication Orbital Welding Machine (fusion + wire)
The SX322 is a high-capacity prefabrication orbital welding machine developed for large-diameter tube fabrication in industries requiring extreme accuracy and weld consistency. It performs orbital TIG welding by fusion or fusion + wire on all steels and exotic alloys, powered by the SAXX power source range.
Optimized for workshop prefabrication, the SX322 improves productivity while maintaining exceptional weld quality. Its multi-process capability allows quick reconfiguration to orbital cutting or beveling, making it a complete tube processing solution.
