TIG orbital welding machine SX172 AVC / OSC

automaticfor pipesfor steel

Overview
The SX172 AVC/OSC prefabrication orbital welding system is engineered for consistent, high-quality tube assembly in controlled environments. Its AVC and OSC functions provide precise arc regulation and motorized electrode movement, making it ideal for thicker wall tubes and multi-pass welding applications. As part of the SAXX-powered SX-Range, the SX172 supports a flexible 1-machine, 3-application workflow and allows fast changeover between welding, cutting, and beveling with minimal setup time.

Main data
TUBE OD RANGE: 0.625″–6.625″ (16–173 mm)
COOLING SYSTEM: Water-cooled
FUNCTIONS: Orbital TIG welding with AVC / OSC

Product Advantages

• Orbital TIG welding with AVC / OSC for precise arc control and consistent weld quality
• Arc Voltage Control (AVC) automatically maintains constant electrode-to-tube distance during welding
• Oscillation (OSC) system enables controlled multi-pass welding and uniform weld bead profiles
• Suitable for thick wall tubes up to 12.7 mm (0.5″), ideal for demanding industrial applications
• Motorized axial sweep ±10 mm (0.39″) for accurate electrode positioning and weld coverage
• Concentric clamping system minimizes tube distortion and ensures precise alignment
• Automatic orbital rotation delivers uniform weld penetration around the tube circumference
• Stainless steel clamping jaws prevent tube contamination and protect internal surfaces
• Compatible with all steels and exotic alloys, including stainless steel and high-purity materials
• Powered by SAXX welding power sources for reliable, automated prefabrication welding
• 1 machine – 3 applications: welding, cutting, and beveling with fast changeover using only two setting screws
• Designed for workshop prefabrication, reducing on-site work, installation time, and rework
