Connect supply gases to Core or CorePlus

Make sure that the supply gas lines are correctly connected to the Core™ or CorePlus™ gas connect console.

If you have a VWI™ or OptiMix™ gas connect console, refer to Connect the supply gases and shield water to or.

  • Make sure that you have the correct supply gas hoses before you connect them.
  • Hypertherm® recommends a minimum internal diameter of 10 mm (0.375 inch) for supply-gas hoses that are 76 m (250 feet) or less.

    Regulators

    Note:

    For the best results, make sure that the cutting system is prepared to operate and the gases are flowing when you select the gas regulator settings. This is almost equivalent to doing a test for gas preflow and cutflow.
  2. After installation is complete, fully pressurize the system, and look for gas leaks.

    Your system installer or a licensed plumber can do this for you.
