Orbital welding head SATO-115 AVC/OSC

water-cooledTIGGTAW

Overview The SATO-115 AVC/OSC open head orbital weld head is engineered for high-precision orbital TIG welding on tube outer diameters from 0.75 to 4.5 inches (19 to 115 mm). Suited for demanding sectors such as power generation, chemical processing and petrochemical industries, it produces consistent welds on stainless steel and exotic alloys.

Key Functions Integrated arc voltage control (AVC) and oscillation (OSC) ensure precise control of arc length and electrode positioning for multi-pass applications. The motorized AVC maintains a constant electrode-to-tube distance while OSC provides uniform bead distribution on thicker walls. Designed for confined spaces, the compact open head pairs with a SAXX power source and a 200 A liquid-cooled system for continuous production use.
