SECTION 7: TROUBLESHOOTING
Contact tips and nozzles should be cleaned frequently. Spatter buildup may cause bridging
between nozzle and tip. This could cause electrical shorting between the nozzle and work
piece as well as poor or improper gas flow. Regularly inspect the conductor tube, handle,
cable, and other parts of the MIG Gun for abrasion, cuts, or undue wear. Replace or repair
any parts found deficient. Refer to www.Tweco.com for MIG Gun troubleshooting chart(s).
