OX-6625AO1 AVC/OSC Open Head Orbital Weld Head

TUBE OD RANGE: 1 – 6.625″ / 25 – 170 mm
COOLING SYSTEM: Water-cooled torch
FUNCTION: Orbital TIG welding with AVC/OSC system

The AXXAIR OX-6625AO1 open head orbital TIG weld head delivers exceptional welding performance for larger-diameter tubes and pipes ranging from 1.5–6.625″ (38–170 mm) outside diameter. Combining a compact footprint with increased rigidity and a modular design, the OX-6625AO1 provides exceptional weld quality, even in restricted working areas.

Available for welding with or without filler wire, the OX-6625AO1 features an integrated AVC (Arc Voltage Control) and OSC (Oscillation) system, enabling precise torch positioning, improved fusion control, and superior weld consistency. Designed for use both in the workshop and in the field, this open orbital welding head offers the versatility and productivity required for today’s most demanding industrial welding applications.
