A-2 INST ALLA TION SP-125 PLUS Read entire installation section before starting installation. SAFETY PRECA UTIONS IDENTIFY AND LOCA TE COMPONENTS If you have not already done so, unpack the SP-125 Plus from its carton and remove all packing material around the SP-125 Plus.
A-3 INST ALLA TION SP-125 PLUS SELECT SUIT ABLE LOCA TION 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.
SP-125 PLUS A-4 INST ALLA TION 3. Route the cable under and around the back of the Wire Feed Gearbox (6). 4. For GMAW Only: Refer to Figure A.2. As deliv- ered, the SP-125 Plus is wired for positive polarity. This is the appropriate configuration for the Gas Metal Arc Welding (GMAW) process.
A-5 INST ALLA TION SP-125 PLUS 3. Attach the flow regulator to the cylinder valve and tighten the union nut securely with a wrench. The flow regulator for carbon dioxide must have a plas- tic washer seated in the fitting that attaches to the cylinder to prevent leakage.
A-6 INST ALLA TION SP-125 PLUS CODE REQUIREMENTS FOR INPUT CONNECTIONS This welding machine must be connected to power source in accordance with applicable elec- trical codes.
SP-125 PLUS B-1 OPERA TION Read entire Operation section before operating the SP-125 Plus. ELECTRIC SHOCK can kill. • Do not touch electrically live parts or electrode with skin or wet clothing. Insulate yourself from work and ground. • Always wear dry insulating gloves.
SP-125 PLUS SP-125 PLUS B-2 OPERA TION GENERAL DESCRIPTION The SP-125 Plus is a complete semiautomatic con- stant voltage DC arc welding machine. Included is a solid state controlled, single phase constant voltage transformer/ rectifier power source and a wire feeder for feeding solid steel electrode and cored electrode.
SP-125 PLUS B-3 OPERA TION FIGURE B.1a Refer to Figure B.1b 4. Circuit Breaker – Protects machine from damage if maximum output is exceeded. Button will extend out when tripped (Manual reset).
SP-125 PLUS B-4 OPERA TION FIGURE B.3 Note: The brake should be adjusted with a spool of wire installed. When properly adjusted it should move freely but not coast. Friction Brake Adjustments 1 . With wire spool installed, check free movement and coast of the spool.
SP-125 PLUS B-5 OPERA TION Shielding Gas When using the GMAW process, a cylinder of shield- ing gas, must be obtained. Refer to the ACCES- SORIES section for more information about selecting gas cylinders for use with the SP-125 Plus. 1. For CO 2 , open the cylinder very slowly.
SP-125 PLUS B-6 OPERA TION 9. To stop welding, release the gun trigger and then pull the gun away from the work after the arc goes out. 10. When no more welding is to be done, close valve on gas cylinder (if used), momentarily operate gun trigger to release gas pressure, and turn off the SP-125 Plus.
SP-125 PLUS B-7 OPERA TION O VERLO AD PR O TECTION Output Overload The SP-125 Plus is equipped with a circuit breaker which protects the machine from potential damage from excessive output current. The circuit breaker but- ton will extend out when tripped.
SP-125 PLUS B-8 LEARNING T O WELD LEARNING T O WELD No one can learn to weld simply by reading about it. Skill comes only with practice. The following pages will help the inexperienced operator to understand weld- ing and develop this skill.
SP-125 PLUS B-9 LEARNING T O WELD The “arc stream” is seen in the middle of the picture. This is the electric arc created by the electric current flowing through the space between the end of the wire electrode and the base metal. The temperature of this arc is about 6000°F, which is more than enough to melt metal.
SP-125 PLUS B-10 LEARNING T O WELD 2. Can I afford the extra expense, space, and lack of portability required for gas cylinders and gas sup- ply? 3. Do I require clean, finished-looking welds? If you have answered yes to all the above questions GMAW may be the process for you.
SP-125 PLUS B-11 LEARNING T O WELD FIGURE B.12 Penetration Unless a weld penetrates close to 100% of the metal thickness, a butt weld will be weaker than the material welded together. In the example shown in Figure B.13, the total weld is only half the thickness of the material thus the weld is only approximately half as strong as the metal.
SP-125 PLUS B-12 LEARNING T O WELD FIGURE B.16 Vertical-down Welding Refer to Figure B.17 Vertical-down welds are applied at a fast pace. These welds are therefore shallow and narrow and, as such, are excellent for sheet metal. Vertical-down welds may be applied to 5/32” (3.
SP-125 PLUS B-13 LEARNING T O WELD ARC RAYS can burn eyes and skin. When using an open arc process, it Is necessary to use correct eye, head and body protection. Protect yourself and others, read “ARC RAYS can burn” at the front of this manual. 2.

For general welding, it is not necessary to weave the arc, neither forward or backward nor sideways.
SP-125 PLUS B-15 LEARNING T O WELD MA CHINE SET UP FOR THE GMA W (MIG) PROCESS 1. See PROCESS GUIDELINES in the OPERATION section for selection of welding wire and shielding gas, and for range of metal thicknesses that can be welded. 2. See the Application Guide on the inside of wire feed section door for information on setting the controls.
Helpful Hints 1. For general welding, it is not necessary to weave the arc, neither forward or backward nor sideways. Weld along at a steady pace. You will find it easier.
SP-125 PLUS B-17 LEARNING T O WELD 4. After you strike the arc, practice the correct electri- cal stickout. Learn to distinguish it by its sound. 5. When you are sure that you can hold the correct electrical stickout, with a smooth “crackling” arc, start moving.
SP-125 PLUS B-18 LEARNING T O WELD Proper Gun Handling Most feeding problems are caused by improper han- dling of the gun cable or electrodes. 1. Do not kink or pull the gun around sharp corners 2. Keep the gun cable as straight as practical when welding.

SP-125 PLUS MAINTENANCE SAFETY PRECA UTIONS 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.
SP-125 PLUS D-2 MAINTENANCE GUN AND CABLE MAINTENANCE FOR MA GNUM™ 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.
SP-125 PLUS D-3 MAINTENANCE COMPONENT REPLA CEMENT PR OCEDURES CHANGING THE CONT A CT TIP 1. Unplug or turn power switch to Off “O” position. 2. Refer to Figure D.2. Remove the gas nozzle from the gun by unscrewing counter-clockwise. 3. Remove the existing contact tip from the gun by unscrewing counter-clockwise.
SP-125 PLUS D-4 MAINTENANCE CHANGING LINER NOTICE: The variation in cable lengths pre- vents the interchangeability of liners. Once a liner has been cut for a particular gun, it should not be installed in another gun unless it can meet the liner cutoff length requirement.
SP-125 PLUS D-5 MAINTENANCE GUN HANDLE P ARTS The gun handle consists of two halves that are held together with a collar on each end. To open up the handle, turn the collars approximately 60 degrees counter-clockwise until the collar reaches a stop. Then pull the collar off the gun handle.
