Pro-MIG 175 For use with machine Code Numbers 11009 Safety Depends on You Lincoln arc welding and cutting equipment is designed and built with safety in mind. However, your overall safety can be increased by proper installation ... and thought- ful operation on your part.
351040, Miami, Florida 33135 or CSA Standard W117.2-1974. A Free copy of “Arc Welding Safety” booklet E205 is available from the Lincoln Electric Company, 22801 St. Clair Avenue, Cleveland, Ohio 44117-1199. BE SURE THAT ALL INSTALLATION, OPERATION, MAINTENANCE AND REPAIR PROCEDURES ARE PERFORMED ONLY BY QUALIFIED INDIVIDUALS.
ELECTRIC SHOCK can kill. 3.a. The electrode and work (or ground) circuits are electrically “hot” when the welder is on. Do not touch these “hot” parts with your bare skin or wet clothing. Wear dry, hole-free gloves to insulate hands.
WELDING SPARKS can cause fire or explosion. 6.a. Remove fire hazards from the welding area. If this is not possible, cover them to prevent the welding sparks from starting a fire. Remember that welding sparks and hot materials from welding can easily go through small cracks and openings to adjacent areas.

SELECT SUITABLE LOCATION Locate the welder in a dry location where there is free circulation of clean air into the louvers in the back and out the front of the unit. A location that minimizes the amount of smoke and dirt drawn into the rear louvers reduces the chance of dirt accumulation that can block air passages and cause overheating.
Work Cable Installation Refer to Figure A.2. 1. Open the wire feed section door on the right side of the Pro-MIG 175. 2. Pass the end of the work cable that has the termi- nal lug with the smaller hole through the Work Cable Access Hole (1) in the case front.
Keep cylinder upright and chained to support • Keep cylinder away from areas where it may be damaged. • Never lift welder with cylinder attached. • Never allow welding electrode to touch cylinder. • Keep cylinder away from welding or other live electrical circuits.
230 Volt Input Connection The Pro-MIG 175 is shipped from the factory connect- ed for 230 volt input power. If the welder has been reconnected for 208 volt input power and 230 volt input is desired, perform the following reconnection...
OPERATION GENERAL DESCRIPTION The Pro-MIG 175 is a complete semiautomatic con- stant voltage DC portable arc welder. Included is a tap-switch controlled, single phase constant voltage transformer/rectifier power source and a wire feeder with welding gun for feeding .023" (0.6 mm) through .030"...
No external shielding gas is required when used with Lincol .035” (0.9 mm) Innershield NR MP electrode. Spindle accommodates both 8 in. (200 mm) diame- ter and 4 in. (100 mm) diameter spools of wire. WELDING CAPABILITY The Pro-MIG 175 is rated at 130 amps, 20 volts, at 30% duty cycle on a ten minute basis.
WELDING OPERATIONS SEQUENCE OF OPERATION Wire Loading Refer to Figure B.2 and B.3. The machine power switch should be turned to the OFF (“O”) position before working inside the wire feed enclosure. The machine is shipped from the factory ready to feed 8”...
Wire Threading Refer to Figure B.4 1. Release the Spring Loaded Pressure Arm (1) rotate the Idle Roll Arm (2) away from the Wire Feed Drive Roll (3). Ensure that the groove size in the feeding position on the drive roll matches the wire size being used.
FIGURE B.6 Contact Tip Wire Electrode 3/8"– 1/2"(10-13mm) Contact Tip to Work Distance(CTWD) Making A Weld 1. See “Process Guidelines” in this section for selec- tion of welding wire and shielding gas and for range of metal thicknesses that can be welded. 2.
The Pro-MIG 175 is suitable for .035" aluminum wire and .023"– .035" stainless wire. Refer to Table B.1 for recommended procedure settings. (Requires K586-1 regulator kit and K664-2 Aluminum - Stainless Feeding Kit.) CAUTION It is important when changing between welding with steel wire and aluminum to exchange feeding components due to the lubricant applied to steel wire.
OPTIONAL ACCESSORIES 1. K549-1 .035" (0.9 mm) Innershield® Welding Kit — Includes a contact tip, a gasless nozzle and a .030/.035 (.8/.9mm) cable liner to permit the Magnum™ 100L gun and cable to use .035" (0.9 mm) diameter flux-cored electrode. The fitting on the end of the liner is stenciled with the maximum rated wire size (.045"/1.2 mm).
INNERSHIELD (FCAW) CONVERSION Several changes are needed to convert the unit for operation with the Innershield (FCAW) process. The K549-1 Innershield Kit includes all the necessary accessories for this conversion and is provided for this purpose. The following conversions should be made using the contents of this kit: 1.
POWER SOURCE COMPARTMENT In extremely dusty locations, dirt may clog the air passages causing the welder to run hot. Blow dirt out of the welder with low pressure air at regular intervals to eliminate excessive dirt and dust build-up on interval parts.
GUN AND CABLE MAINTENANCE FOR MAGNUM™ 100L GUN Gun Cable Cleaning Clean cable liner after using approximately 300 lbs (136 kg) of solid wire or 50 lbs (23 kg) of flux-cored wire. Remove the cable from the wire feeder and lay it out straight on the floor.
COMPONENT REPLACEMENT PROCEDURES CHANGING THE CONTACT TIP 1. Refer to Figure D.2. Remove the gas nozzle from the gun by unscrewing counter-clockwise. 2. Remove the existing contact tip from the gun by unscrewing counter-clockwise. 3. Insert and hand tighten desired contact tip. 4.
Set Screw Brass Cable Connector Liner Assembly (Liner bushing to be sealed tight against brass cable connector) FIGURE D.2 Liner trim length CHANGING LINER NOTICE: The variation in cable lengths prevents the interchangeability of liners. Once a liner has been cut for a particular gun, it should not be installed in anoth- er gun unless it can meet the liner cutoff length requirement.
