Water-cooled welding head X-750 series

orbitalfor tubesfor microjoining

Overview
The AXXAIR X-750 is an orbital microfit closed weld head for welding tubes and micro‑fittings in confined or tight areas. Water‑cooled construction and grease‑free components make it suitable for cleanroom and high‑purity environments common in semiconductor, aerospace and pharmaceutical applications. The unit supports high duty‑cycle operation and features a quick‑connect system for efficient setup and maintenance.

Product Advantages

• Designed for tight spaces: ideal for welding tubes and micro‑fittings in confined or restricted environments.
• Grease‑free operation: compatible with cleanroom and high‑purity requirements.
• Quick‑connect stainless steel collets: cover 3–19.05 mm (0.118"–¾") OD with secure retention without set screws.
• Adjustable force clamping system: allows precise adjustment of collet clamping force and assists opening after welding.
• Water‑cooled design: supports high duty‑cycle orbital welding for consistent performance during prolonged operations.
• Easy maintenance: rotor cleaning and electrode replacement aided by an integrated tool in the machine body.

Accessories
Offset electrode kit available for microfit‑to‑microfit welding.
