Connect the gas supply

  1. Make sure that the correct gas inlet fitting is installed.
    • CSA models come with an industrial interchange quick-disconnect nipple with 1/4 NPT threads. Tighten the fitting to 11.3 N·m (100 lbf·in). The fitting comes with thread sealant applied.
    • CE/CCC models come with a British Pipe Thread adapter G-1/4 BSPP with 1/4 NPT threads. Tighten the adapter to 10.2 N·m (90 lbf·in).
    The image shows the gas inlet fitting for CSA models and for CE/CCC models and where the fitting installs on the plasma power supply.

  2. Get an inert-gas hose with the correct internal diameter.
    • For hoses that are less than 15 m (50 feet), use an internal diameter of 10 mm (3/8 inch) or greater.
    • For hoses that are 15 m – 30 m (50 feet – 100 feet), use an internal diameter of 13 mm (1/2 inch) or greater.
    • Do not use hoses with an internal diameter less than 10 mm (3/8 inch). Hoses that are too small can cause problems with cut quality and cut performance.
  3. Connect the gas hose to the gas inlet fitting.

    Refer to Inlet gas pressure requirements (while gas is flowing).
