TUBE OD RANGE: 0.625–6.625″ / 16–173 mm
COOLING SYSTEM: Air or water cooled
FUNCTIONS: Orbital TIG welding by fusion or fusion + wire
SX172 Prefabrication Orbital Welding Machine (fusion + wire)
The SX172 prefabrication orbital welding system is engineered for accurate and repeatable tube assembly prior to on-site installation. Using orbital TIG welding by fusion or fusion + wire, it ensures consistent weld quality on stainless steel, carbon steel, and exotic alloys.
Powered by the SAXX welding power supply, the SX172 supports efficient workshop prefabrication and can be rapidly converted to orbital cutting or beveling, reducing equipment footprint and production time.
