Air-cooled welding head SAMX-25 series

water-cooledfor tubeshigh-precision

Overview
The AXXAIR SAMX-25 microfit closed weld head with cassettes is designed to deliver precision and reliability for a wide range of tube and fitting configurations. Built to accommodate diameters starting at 6 mm (0.236"), the SAMX-25 offers versatility for tube-to-tube, tube-to-fitting, and fitting-to-fitting welding applications in industries such as semiconductors, aerospace, and pharmaceuticals.

Main capabilities
Tube OD range: 0.236 - 1" / 6 – 25.40 mm
Cooling: Air or water cooled (depending on variant)

Key features

• High level of performance with a high duty cycle.
• Grease-free operation: compatible with clean room standards.
• Optimized cassette clamping system ensures proper tube positioning and prevents deformation.
• Optimized inert gas diffusion for welds with very limited coloration.
• Easy maintenance and cleaning: single integrated tool for disassembly, electrode adjustment/replacement and jaw positioning.
• Constant locking effort ensures steady cassette holding without risk of over-tightening.
• Belt hook for convenient carrying and easy access.
