ROUTINE MAINTENANCE
DRIVE ROLLS AND GUIDE TUBES
After feeding every coil of wire, inspect the drive roll section. Clean the assembly as necessary. Do not use solvent to clean the drive roll assembly as it may wash the lubricant out of the bearings. The drive rolls and guide tubes are stamped with the wire sizes they will feed. If a wire size other than that stamped on the rolls is to be used, the rolls and guide tubes must be changed.
The drive rolls for 0.045 and 0.052 cored electrode and 1/16, 0.068, 5/64, 3/32, and 7/64 electrode have a double set of teeth so they can be reversed for additional life. Between the two knurled rolls (except 1/16 and smaller rolls) is a shim washer which limits the damage to the electrode if wire feeding problems occur. Drive rolls for 0.023 through 0.052 solid electrodes have no teeth.
Refer to the instructions included with the drive roll kit for installation and replacement of the drive rolls on the wire feeder.
WIRE REEL MOUNTING
To prolong the life of the reel shaft on the 50 to 60 lb coils, periodically coat it with a thin
layer of grease. No maintenance to the two position brake is required. If the brake shoe wears through to metal, replace the brake assembly.
