A-3 INST ALLA TION PRO 100 A-3 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 INST ALLA TION PRO 100 A-4 and installation details. Connecting Gun Cable to the PR O 100 1. Refer to Figure A.2. Unplug the machine or turn power switch to the OFF “ O ” position. 2. Pass the insulated terminals of the gun trigger con- trol leads, one at a time, through the Gun Cable and Control Lead Access Slot (2) in the case front.
2 . With the cylinder securely installed, remove the cylinder cap. Stand to one side away from the out- let and open the cylinder valve very slightly for an instant. This blows away any dust or dirt which may have accumulated in the valve outlet. BE SURE TO KEEP YOUR FACE AWAY FROM THE VALVE OUTLET WHEN “ CRACKING ” THE VALVE.
A-6 INST ALLA TION PRO 100 A-6 INPUT CONNECTIONS FIGURE A.6 Refer to Figure A.6. The PRO 100 has a power input cable located on the rear of the machine. CODE REQUIREMENTS FOR INPUT CONNECTIONS This welding machine must be connected to power source in accordance with applicable elec- trical codes.
B-1 OPERA TION B-1 PRO 100 Read entire operation section before operating the PRO 100. 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 OPERA TION B-2 ● No external shielding gas is required when used with Lincoln Innershield .035 ” (0,9 mm) NR ® -211- MP electrode. ● Accommodates 4 ” (100 mm) diameter spool of wire. Will accommodate 8 ” (200 mm) diameter with optional spindle.
B-3 OPERA TION B-3 FIGURE B.1a FIGURE B.1b WELDING OPERA TIONS SEQUENCE OF OPERA TION Wire Loading Refer to Figure B.2 AND B3. 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 4 ” (100 mm) diameter spools.
Gun Handle Gas Diffuser/ Contact Tip Gas Nozzle FIGURE B.5 B-4 OPERA TION B-4 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.
B-5 OPERA TION B-5 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. See the Application chart on the inside of the wire feed compartment door for information on setting the PRO 100 controls.
B-6 OPERA TION B-6 lower cost. A mixed gas consisting of 75 to 80% Argon and 20 to 25% CO 2 is recommended for weld- ing on heavier gauge [12 gauge (2,5 mm) for exam- ple] steel. The PRO 100 is suitable for .035" aluminum wire and .030" stainless wire.
B-7 LEARNING T O WELD B-7 PRO 100 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 welding and develop this skill.
B-8 LEARNING T O WELD B-8 PRO 100 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-9 LEARNING T O WELD B-9 PRO 100 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.
B-10 LEARNING T O WELD B-10 PRO 100 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-11 LEARNING T O WELD B-11 PRO 100 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-12 LEARNING T O WELD B-12 PRO 100 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.
B-13 LEARNING T O WELD B-13 PRO 100 Helpful Hints 1. For general welding, it is not necessary to weave the arc, neither forward or backward nor sideways.
B-14 LEARNING T O WELD B-14 PRO 100 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.
B-15 LEARNING T O WELD B-15 PRO 100 FIGURE B.24 3. The Correct Electrical Stickout (ESO) The electrical stickout (ESO) is the distance from the end of the contact tip to the end of the wire. See Figure B.24. Once the arc has been established, maintaining the correct ESO becomes extremely important.
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. Look at the molten puddle constantly, 6.
B-17 LEARNING T O WELD B-17 PRO 100 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.
