ROUTINE MAINTENANCE

DRIVE ROLLS AND GUIDE TUBES

After feeding any coil of wire, inspect the drive roll sec- tion. Clean it as necessary. Do not use a solvent for cleaning the idle rolls(s) because it may wash the lubri- cant out of the bearing. The drive roll(s) and guide tubes are stamped with the wire sizes they will feed. If you use a wire size other than that stamped on the rolls, the roll(s) and guide tubes must be changed.

The drive rolls using the knurled "V-groove" design have a double set of teeth so they can be reversed for additional life. Between the two knurled rolls for .068 through .120" is a shim washer which limits the dam- age to the wire to a minimum should wire feeding prob- lems occur. When drive rolls are interchanged, leave the three socket head screws of the roll assembly loose until it is re-assembled on the drive shaft. Then tighten all three. Be sure the roll faces and spacer faces are thoroughly cleaned before re-assembly. Drive rolls for 1/16" and smaller solid electrodes using the smooth "V-groove" design have no teeth. They are not reversible.

See the Operation Section for drive roll installation instructions.

See Table C.2 in the Accessories section for drive roll and guide tube kits.

PERIODIC MAINTENANCE

CONTROL BOX

Every six months open and inspect the control section. The accumulated dirt should be gently blown off all of the electrical components. See Figure D.3 for compo- nent locations. Be sure the air that is being used is dry. Check the contacts of the large plug-in relay.

A spatter resistant shield protects the digital meter. This shield must always be installed. If it breaks or becomes damaged, replace it by removing the two screws securing its frame, installing a new shield, and reattaching the frame.

WIRE DRIVE MOTOR AND GEAR BOX

Every year examine the gearbox. Paint the gear teeth with molydisulfide-filled grease such as Non-Fluid Oil Corporation’s A-29 Special/MS Lubricant. Do not use a graphite grease.

Check the motor brushes. Replace if they are worn down to 1/4" or less. When ordering feed motor brush- es, give all information from the motor nameplate.
