Key data
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

Overview
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 delivers consistent welds on stainless steel, carbon steel and exotic alloys. Powered by SAXX welding power sources, the SX172 supports efficient workshop prefabrication and can be rapidly converted to orbital cutting or beveling, reducing equipment footprint and production time.

Product Advantages

• Orbital TIG welding by fusion or fusion + wire for repeatable, consistent weld profiles
• Accurate axial adjustment of electrode and tube for precise joint alignment
• Micrometric arc-gap adjustment without special tooling for optimal weld control
• Mechanical OD tracking to maintain constant electrode-to-tube distance and compensate for tube ovalization
• Concentric clamping system to minimize tube distortion during welding
• Automatic orbital rotation for uniform penetration and weld consistency
• Stainless steel clamping jaws to prevent contamination and protect internal tube surfaces
• Suitable for stainless steel, carbon steel and exotic alloys across multiple industries
• Powered by SAXX welding power sources for automated, reliable operation
• One machine — three applications: welding, cutting and beveling with fast changeover using two setting screws
• Ideal for workshop prefabrication to reduce on-site welding time and installation risk
