Examine the torch

Check the torch for damage or excess wear on the O-rings, torch main body, and torch insulator.

  1. Examine the torch for:
    • Damage or excess wear on the external O-rings that are on the front of the torchSide profile of XPR torch with arrows pointing to external O-rings
    • Damage or excess wear on the internal O-rings that are on the rear of the torchBack end of torch showing location of O-rings on receptacle connection points
    • Dry O-rings
    • Over-lubricated O-rings
    • Cracks in the torch main body
    • Cracks in the torch insulator
  2. Replace any O-rings that have damage or excess wear.

    Torch rebuild kits are available from Hypertherm®. Refer to Preventive maintenance kits.

  3. If you find cracks in the torch main body or torch insulator, replace the entire torch main body.

    Refer to Install the torch into the torch receptacle.

  4. Replace the torch water tube if you find pitting or bends.
  5. Clean and lubricate the torch if it does not need replacement:

    1. Use a clean, lint-free cloth to wipe the internal and external surfaces.
    2. Use compressed air to remove debris from the internal and external surfaces.

      A cotton swab can be used for internal surfaces that are difficult to reach. Do not leave cotton fibers inside of the torch.

    3. Apply a thin film of silicone lubricant (027055) to any O-ring that does not need replacement and that looks dry.

      The O-rings should look shiny. Too much lubricant can prevent gas flow. Remove excess lubricant if found.

  6. Before you supply power to the cutting system, install the following components:
    • Consumables in the torch.
    • Torch in the torch receptacle.
