Orbital welding head X-500 series

water-cooledair-cooledprecision metal joining

Overview
The AXXAIR X-500 is the thinnest closed orbital welding head in the AXXAIR range, engineered for precision orbital welding of micro‑fittings and small‑diameter tubes in confined spaces. Designed for critical environments — semiconductor fabrication, aerospace assembly and pharmaceutical production — it supports grease‑free operation and optimized inert gas diffusion to ensure clean, repeatable welds.

Key Data
TUBE OD RANGE: 0.118 – 0.5" / 3 – 12.7 mm
COOLING SYSTEM: Air or water cooled

Product Advantages

• Ultra‑slim profile: minimum clearance ½" (12.7 mm) for access in tight spaces.
• Microfit compatibility: designed for Microfit‑to‑Microfit joints.
• Diameter‑specific clamping cassettes: secure fit across 3–12.7 mm range.
• Grease‑free operation: suitable for cleanroom and high‑purity environments.
• Optimized inert gas diffusion: minimizes weld discoloration.
• Cooling options: air‑cooled and liquid‑cooled variants available.
• Productivity: up to 20 welds/hour (air‑cooled) and 30 welds/hour (liquid‑cooled) on 12.7 mm Ø, 1.24 mm thick stainless tube.
• Easy maintenance: integrated single tool for rotor disassembly, cleaning and electrode handling.
• Control compatibility: works with AXXAIR power supplies or integrates with third‑party systems; AMI‑compatible variants available.
