Changing Liner Ref. 801 891-B Tools Needed: Turn Off power at welding power source first. 1 Nozzle 2 Contact Tip 3 Liner Remove and replace liner. Reinstall parts as shown. 1 2 3 5-4. Troubleshooting Trouble Remedy Gun tube assembly loose. Tighten nut at base of gun tube assembly. No weld output; gun/feeder does not work. Place Power switch on welding power source in the On position (see welding power source Owner’s Manual). Erratic weld output. Tighten and clean all connections. Pressing gun/feeder trigger does not energize welding power source; welding wire is not energized; shielding gas does not flow. Secure plug from gun/feeder trigger cord into 4-socket receptacle on welding power source (see Section 3-3, field kit instructions F207 643, or appropriate welding power source Owner’s Manual). Wire feeds, shielding gas flows, but welding wire is not energized. Secure control cable leads in welding power source (see field kit instructions F207 643 or appropriate welding power source Owner’s Manual). See Troubleshooting section in welding power source Owner’s Manual. Wire feeds erratically. Check and correct drive roll pressure (see Section 3-4). Clean or replace drive roll; clean or replace liner (see Sections 5-2 and 5-3). OM-1216 Page 15 Notes OM-1214 Page 16 SECTION 6 . ELECTRICAL DIAGRAMS 186 451 Figure 6-1.
