UHP gas distribution and gas cabinet (BCU) automated construction.
Semiconductor fab UHP gas distribution often sets SEMI F20-type inner-bead targets for corrosive process gas lines. The C-Series enclosed welding chamber maintains a 360-degree argon envelope around the joint to support inner-bead oxidation control. Actual installation time depends on purge setup, WPS, site access, and QA procedure.
The FXT20's 5A minimum arc initiation is critical for the small-diameter instrument and analytical tubing in process gas distribution where conventional 30A+ arc starts would burn through. The 200-group recipe library stores parameter sets for EP-grade SUS316L electropolished tubing across the manufacturer-specific surface finish classes (Ra >=0.5 um, Ra >=0.25 um, Ra >=0.15 um) that drive parameter selection in fab construction. The C5 / C10 heads handle the small-diameter tubing that dominates fab gas distribution.
