| machine. |
2. | Remove the gas nozzle from the gun |
| by unscrewing |
3. | Remove the existing contact tip from |

| feeder end of the cable. Pull the liner |

| liner bushing is stenciled appropriately |
| for the wire size being used. |
7. | Fully seat the liner bushing into the |
| connector. Tighten the set screw on the |
| brass cable connector. At this time, the |
| gas diffuser should not be installed onto |
| the end of the gun tube. |

| removed from the gun tube, be sure the |
| cable is straight, and then trim the liner |
| to the length shown in the Figure D.2. |
