A-2 A-2 INST ALLA TION Read entire installation section before starting installation. SAFETY PRECAUTIONS IDENTIFY AND LOCA TE COMPONENTS If you have not already done so, unpack the Welder from its carton and remove all packing material Remove the following loose items from the carton (see Figure A.
A-3 A-3 INST ALLA TION 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.
A-4 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 welder is wired for positive polarity. This is the appropriate configuration for the Gas Metal Arc Welding (GMAW) process.
A-5 A-5 INST ALLA TION 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 A-6 INST ALLA TION CODE REQUIREMENTS FOR INPUT CONNECTIONS This welding machine must be connected to power source in accordance with applicable elec- trical codes.
B-1 B-1 OPERA TION Read entire Operation section before operating the WELDMARK 135 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.
B-2 B-2 OPERA TION GENERAL DESCRIPTION The WELDMARK 135 PLUS is a complete semiauto- matic constant voltage DC arc welding machine. Included is a solid state controlled, single phase con- stant voltage transformer/ rectifier power source and a wire feeder for feeding solid steel electrode and cored electrode.
B-3 B-3 OPERA TION FIGURE B.1a 4. Circuit Breaker – Protects machine from damage if maximum output is exceeded. Button will extend out when tripped (Manual reset). Refer to Figure B.1b. 5. Gun Trigger - Activates welding output, wire feed, and gas solenoid operation.
B-4 B-4 OPERA TION FIGURE B.3 Friction Brake Adjustment With wire spool installed on the spindle shaft and the wing nut loose, turn the spool by hand while slowly tightening the wing nut until a light drag is felt. Tighten the wing nut an additional 1/4 turn.
B-5 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 WELDMARK 135 PLUS. 1. For CO 2 , open the cylinder very slowly.
B-6 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 welder.
B-7 B-7 OPERA TION OVERLOAD PROTECTION Output Overload The WELDMARK 135 PLUS is equipped with a circuit breaker which protects the machine from potential damage from excessive output current. The circuit breaker button will extend out when tripped. The cir- cuit breaker must be manually reset.
B-8 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.
B-9 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.
B-10 B-10 LEARNING T O WELD For GMAW (MIG) Process 1. Is most of my welding performed on 16 gauge and lighter materials? 2. Can I afford the extra expense, space, and lack of portability required for gas cylinders and gas sup- ply? 3.
B-1 1 B-1 1 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.
B-12 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.
B-13 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. The Correct Way To Strike An Arc 1.
B-14 B-14 LEARNING T O WELD Mild Steel 16 gauge or 1/16 inch (1.6 mm) Electrode 0.035" (0.9 mm) NR-211-MP Innershield Wire Voltage Setting “ V ” E Wire Feed Speed “ o|o ” 2 For the WELD MARK 135 PLUS, use the following: Helpful Hints 1. For general welding, it is not necessary to weave the arc, neither forward or backward nor sideways.
B-15 B-15 LEARNING T O WELD MACHINE 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.
B-17 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.
B-18 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. 3.

MAINTENANCE SAFETY PRECAUTIONS ELECTRIC SHOCK can kill. • Disconnect input power by removing plug from receptacle before working inside WELD- MARK 135 PLUS. Use only grounded receptacle. Do not touch electrically “ hot ” parts inside WELDMARK 135 PLUS.
D-2 D-2 MAINTENANCE 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.
D-3 WELDMARK 135 PLUS D-3 MAINTENANCE COMPONENT REPLACEMENT PROCEDURES CHANGING THE CONT ACT 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.
D-4 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.
If machine case sides and top are removed, the case front must be supported. Failure to do this could result in mechanical or electrical damage to the welder.
