SVM 113-A January , 1996 Safety Depends on Y ou Lincoln arc welding and cutting equipment is designed and built with safety in mind. However , your overall safety can be increased by pr oper installation .
SAFETY i i FOR ENGINE powered equipment. 1.a. T urn the engine off before troubleshooting and maintenance work unless the maintenance work requires it to be running. ____________________________________________________ 1.b. Operate engines in open, well-ventilated areas or vent the engine exhaust fumes outdoors.
SAFETY ii ii ARC RA YS can burn. 4.a. Use a shield with the proper filter and cover plates to protect your eyes from sparks and the rays of the arc when welding or observing open arc welding. Headshield and filter lens should conform to ANSI Z87. I standards.
SAFETY iii iii FOR ELECTRICALL Y powered equipment. 8.a. T urn off input power using the disconnect switch at the fuse box before working on the equipment. 8.b. Install equipment in accordance with the U.S. National Electrical Code, all local codes and the manufacturer ’s recommendations.
SAFETY iv iv PRÉCAUTIONS DE SÛRETÉ Pour votre propre protection lire et observer toutes les instructions et les précautions de sûreté specifiques qui parraissent dans ce manuel aussi bien que les précautions de sûreté générales suiv- antes: Sûreté Pour Soudage A L ’Arc 1.

Read this entire installation section before you start installation. SAFETY PRECAUTIONS Do not attempt to use this equipment until you have thoroughly r ead all the operation and maintenance manuals supplied with your machine.
ST ACKING WELDANPOWER 125 machines CANNOT be stacked. TIL TING Place the machine on a secure, level surface whenev- er you use it or store it. Any surfaces you place it on other than the ground must be firm, non-skid, and structurally sound. The gasoline engine is designed to run in a level posi- tion for best performance.
ELECTRICAL OUTPUT CONNECTIONS See Figure A.1 for the location of the curr ent control dial, weld output terminals, ground stud, cir cuit break- ers, 230 and 115 volt receptacles. WELDING CABLE CONNECTIONS Cable Size and Length Be sure to use welding cables that ar e large enough.

OPERA TING INSTRUCTIONS Read and understand this entire section befor e oper- ating your WELDANPOWER 125. SAFETY INSTRUCTIONS Do not attempt to use this equipment until you have thoroughly r ead all the operation and maintenance manuals supplied with your machine.
RECOMMENDED APPLICA TIONS WELDER The WELDANPOWER 125 provides excellent constant current DC welding output for stick (SMA W) welding and DC TIG welding using the “scratch” starting tech- nique. THE K903 TIG Module can be added as an option to provide high fr equency starting.
WELDER/GENERA TOR CONTROLS See Figure B.1 for the location of the following fea- tures: 1. CURRENT CONTROL DIAL: Adjusts continuous current output. The amperages on the dial corr e- spond to the average amperages needed for spe- cific Lincoln welder rods.

7. CARBURETOR: Mixes air with fuel to obtain the smoothest operation under load or at idle. The WELDANPOWER 125 is shipped with the proper air/fuel mixture adjustment alr eady set. DO NOT ADJUST THE AIR MIXTURE WITHOUT FOL- LOWING THE PROCEDURES OUTLINED BY BRIGGS & STRA TTON.
FIGURE B.3 FUEL SHUT -OFF AND CHOKE CONTROL 3. Set the Idler Control switch to the “AUTOMA TIC” position. See Figure B.4. 4. Place the engine stop switch in the “RUN” position. See Figure B.4. 5. Pull slightly on the recoil starter handle until resis- tance is felt.
BREAK-IN PERIOD Any engine will use a small amount of oil during its “break-in” period. For the gasoline engine on the WELDANPOWER 125, break-in is about 50 running hours. Check the oil frequently during br eak-in. Change the oil after the first 5 hours of operation.
TO USE THE WELDANPOWER 125 FOR WELD- ING: 1. Remove the flange nuts from the weld output ter- minals and place the work and electrode welding cables over the terminals. See Figure B.2. Replace and tighten the flange nuts securely . Be sure the connections ar e tight.

SAFETY PRECAUTIONS • Have qualified personnel do all maintenance and troubleshooting work. • T ur n the engine off before working inside the machine. • Remove guar ds only when necessary to perform maintenance and replace them when the mainte- nance requiring their r emoval is complete.
AIR CLEANER: With normal operating conditions, the maintenance schedule for cleaning and re-oiling the foam pr e-filter is every 25 hours and replacement of the air cleaner filter element every 100 hours. More fr equent servicing is required with dusty operat- ing conditions.
CLEAN OR REPLACE SP ARK PLUG: Clean or replace the spark plug after every 100 hours of opera- tion or every season, whichever comes first. Do not blast the spark plug clean with an abrasive cleaning device. Clean the plug by scraping it or by using a wire brush.
