SAFETY PRECAUTIONS

WARNING

ELECTRIC SHOCK can kill.

•Disconnect input power by remov- ing plug from receptacle before working inside SP-125 PLUS. Use only grounded receptacle. Do not touch electrically “hot” parts inside SP-125 PLUS.

•Have qualified personnel do the maintenance and trouble shooting work.

ITEMS REQUIRING NO

MAINTENANCE

•Drive Motor and Gearbox – Lifetime lubrication

•Fan Motor- Lifetime lubrication.

•Wire Reel Spindle – Do NOT lubricate shaft.

ROUTINE AND PERIODIC MAINTE- NANCE

BEFORE EACH USE

•Check over machine and accessories for any obvious condition that may prevent safe performance or oper- ation, repair or replace items as necessary to correct any abnormal condition.

AFTER 5 MINUTES OF WELDING

or when spatter accumulates in nozzle

•Clean nozzle to avoid bridging between nozzle and contact tip which results in shorted nozzle, poor welds and overheated gun. Hint: Anti-stick spray or gel available from a welding supply distributor may reduce buildup and aid in spatter removal.

AFTER EACH SPOOL OF WIRE FEED

•Remove contact tip and clean inside diameter with short piece of wire

•Clean cable liner – when rough and erratic wire feed- ing occur.

SP-125 PLUS

AFTER FEEDING 50# OF FLUX CORED WIRE OR 300# OF SOLID WIRE

•Unplug machine or turn power switch to OFF – “O” position. Remove gun and cable from machine.

•Remove gas nozzle and contact tip from gun.

•Lay cable out straight - blow out gently into gun end with compressed air. Bend cable back and forth – blow out again – Repeat until clean.

WARNING

Excessive pressure at start may cause the dirt to form a plug.

PERIODICALLY AS REQUIRED

•Blow dirt out of the welder with low pressure air to eliminate excessive dirt and dust buildup that could cause welder to run hot.

•Blow dirt out of: Rectifier & Fan Motor Assembly; PC Board located on Case Side Assembly; and Center Assembly components.

•Vacuum accumulated dirt from gearbox and wire feed section.

•Inspect the incoming guide tube and clean inside diameter if necessary. Replace when excessively worn.

•Replace Contact Tip – when hole is enlarged or elongated (refer to “CHANGING THE CONTACT TIP”, in this section).

•Replace gas nozzle.

•Replace Liner – when wire feeding problems occur and other items have been checked (refer to “CHANGING LINER” procedure in this section).

•Replace internal gun handle parts as necessary (see Procedure at the end of this section).
