How Do I Install A New Wire Casing/Conduit?

  1. Be sure the MIG Gun cables are arranged in a straight line, free from twists, when installing or removing a wire conduit/casing & liner.
    • Remove the old liner by first removing the MIG guns contact tip.
    • Pull the old wire liner out of the conduit/casing assembly from the feeder connector or feeder adapter plug end.
    • Be sure the MIG Gun cables are arranged in a straight line, free from twists, when installing or removing a wire conduit/casing & liner.
    • Make sure the conduit/casing and feeder adapter have been removed from the drive rolls.
    • Loosen any Allen screws or body screws in the torch inner body or docking spool and pull the old conduit/casing out of the assembly from the feeder adapter end.
  2. To install a new wire conduit/casing, first inspect the conduit/casing for cuts or damage. Start from the feeder adapter end of the assembly and begin pushing the conduit/casing through the sheath and/or cable assembly and into the gun. If the conduit/casing should lodge along the way, gently whip or work the cable assembly to aid forward movement.
  3. When the wire conduit/casing stop meets the end of the inner body or docking spool the Allen screw must be securely tightened onto the conduit/casing to prevent its backward movement or pumping action.
  4. To install a new liner, start from the feeder adapter end of the assembly and begin pushing the liner through the feeder adapter & conduit/casing and into the gun or torch. If the liner should lodge along the way, gently whip or work the conduit/casing & liner assembly to aid forward movement.Sometimes on longer conduits/casings and liners it may take 2 people together; one on each end to rotate and twist the conduit/casing to get the liner trough the torch.
  5. Replace gas diffuser, contact tip, and nozzle.
  6. Tighten the flat head set screw in the inner body, or the Allen set screw in the docking spool onto the conduit/casing to prevent backward movement or an unwanted pumping action.
