OPERA TOR’S MANUAL 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 .
FOR ENGINE powered equipment. 1.a. Turn 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.
ii SAFETY 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.
FOR ELECTRICALL Y powered equipment. 8.a. Turn 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.

A-2 INST ALLA TION POWER-ARC 4000 A-2 Read this entire installation section before you start installation. SAFETY PRECAUTIONS Do not attempt to use this equipment until you have thoroughly read all the operation and main- tenance manuals supplied with your machine.
A-3 INST ALLA TION POWER-ARC 4000 A-3 ST ACKING POWER-ARC 4000 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.
A-4 INST ALLA TION POWER-ARC 4000 A-4 MUFFLER DEFLECTOR The POWER-ARC 4000, depending on model, may or may not be shipped with an exhaust deflector. If you received one, you can mount it on the gasoline engine if your needs so require.
A-5 INST ALLA TION POWER-ARC 4000 A-5 ELECTRICAL OUTPUT CONNECTIONS See Figure A.1 for the location of the current control dial, weld output terminals, ground stud, circuit breakers, 240 and 120 volt receptacles. WELDING CABLE CONNECTIONS Cable Size and Length Be sure to use welding cables that are large enough.
A-6 INST ALLA TION POWER-ARC 4000 A-6 Cable Installation Install the welding cables to your POWER-ARC 4000 as follows. See Figure A.1 for the location of parts. 1. The gasoline engine must be OFF to install weld- ing cables. 2. Remove the 1/2 - 13 flanged nuts from the output terminals.
A-7 INST ALLA TION POWER-ARC 4000 A-7 PREMISES WIRING The POWER-ARC 4000 three-wire, grounded neutral generator allows it to be connected to premises wiring. However, the wiring procedure needed to meet the National Electric Code (NEC) regulations as well as city ordinances and can be confusing.
A-8 INST ALLA TION POWER-ARC 4000 A-8 CAUTION Certain Electrical devices cannot be powered by the POWER-ARC 4000. See Table A.2. TABLE A.2 ELECTRICAL DEVICE USE WITH THE POWER-ARC 4000. Type Common Electrical Devices Possible Concerns Resistive Heaters, toasters, incandescent NONE light bulbs, electric range, hot pan, skillet, coffee maker.
B-1 OPERA TION B-1 OPERA TING INSTRUCTIONS Read and understand this entire section before oper- ating your POWER-ARC 4000. SAFETY INSTRUCTIONS Do not attempt to use this equipment until you have thoroughly read all the operation and main- tenance manuals supplied with your machine.
B-2 OPERA TION B-2 The Lincoln warranty covers the Power Arc 4000 (excluding the engine) for 2 years from the date of purchase. The engine is covered by the engine manu- facturer’s warranty policy. RECOMMENDED APPLICA TIONS GENERA TOR The POWER-ARC 4000 gives AC generator output for medium use, non-commercial demands.
B-3 OPERA TION B-3 CONTROLS AND SETTINGS All generator/welder controls are located on the Output Control Panel. Gasoline engine controls are mounted on the engine. See Figures B.1 and B.2 and the explanations that follow. GENERA TOR/WELDER CONTROLS See Figure B.
B-4 OPERA TION B-4 5. GROUND STUD: Provides a connection point for connecting the machine case to earth ground for the safest grounding procedure. 6. 20 AMP CIRCUIT BREAKERS (2): Provide sepa- rate overload current protection for the 120 volt and 240 volt receptacles.
B-5 OPERA TION B-5 ENGINE OPERA TION DO NOT RUN THE ENGINE AT EXCESSIVE SPEEDS. The maximum allowable high idle speed for the POWER-ARC 4000 is 3750 RPM, no load. Do NOT adjust the governor screw on the engine. Severe personal injury and damage to the machine can result if it is operated at speeds above the maximum rated speed.
B-6 OPERA TION B-6 4. Pull the cord rapidly. 5 . If the engine does not start, open the choke slightly and pull the starter cord rapidly again. When the engine starts, gradually open the choke to the “RUN” position. To open the choke fully requires an engine warm-up period of several seconds to several minutes, depending on the temperature.
B-7 OPERA TION B-7 GENERA TOR OPERA TION Be sure that any electrical equipment plugged into the generator’s AC power receptacles can with- stand a ±10% voltage and a ±4% frequency varia- tion. Some electronic devices cannot be powered by the POWER-ARC 4000.

B-1 1 OPERA TION B-1 1 POWER-ARC 4000 Stick welding is probably the most familiar welding process known. A coated ELECTRODE, the weld rod, is clamped into an ELECTRODE HOLDER, an insulated clamping device, which in turn connects to the ELECTRODE CABLE, a heavy wire.
B-12 OPERA TION B-12 POWER-ARC 4000 The Power-Arc 4000 has a voltage output of up to 62 volts which can shock. The electric arc is made between the work and the tip end of a small metal wire, the electrode, which is clamped in a holder that is held by the welder.
B-13 OPERA TION B-13 POWER-ARC 4000 1. The Correct Welding Position Illustrated is the correct welding position for right-handed people. (For left-handed people it is opposite.) Whenever possible, weld from left to right (if right- handed). This enables you to see clearly what you are doing.
B-14 OPERA TION B-14 POWER-ARC 4000 PRACTICE The best way of getting practice in the four skills that enable you to maintain: 1. Correct Welding Position. 2. Correct Way to Strike An Arc. 3. Correct Arc Length. 4. Correct Welding Speed. is to spend a little more time on the following exercise.
B-15 OPERA TION B-15 POWER-ARC 4000 Now weld the two plates together. Weld from left to right (if right-handed). Point the electrode down in he gap between the two plates, keeping the electrodes slightly tilted in the direction of travel. Watch the molten metal to be sure it distributes itself evenly on both edges and in between the plates.
B-16 OPERA TION B-16 POWER-ARC 4000 Vertical-Up Welding The problem, when welding vertical-up, is to put the molten metal where it is wanted and make it stay there. If too much molten metal is deposited, gravity will pull it downwards and make it “ drip ” .
B-17 OPERA TION B-17 POWER-ARC 4000 Overhead Welding Various techniques are used for overhead welding. However, in the interest of simplicity for the inexperi- enced welder, the following technique will probably take care of his needs for overhead welding: 1.
B-18 OPERA TION B-18 POWER-ARC 4000 4. The bead should be put on with a weaving motion, and it should be 1/2-3/4 ” (12.7-19.0mm) wide. Do not let the arc blow over the edge, as that will dull the edge. (See drawing below.) 5. Use the back-stepping method.
B-19 OPERA TION B-19 POWER-ARC 4000 High-Speed Group (AWS E6013) This group includes electrodes which have a moder- ately forceful arc and deposit rates between those of the out-of-position and high-deposit electrodes.
C-1 ACCESSORIES C-1 OPTIONS/ACCESSORIES LINCOLN ELECTRIC ACCESSORIES The following options/accessories are available for your POWER-ARC 4000 from your local Lincoln Distributor. Accessory Set (K875) – Includes the following: • Twenty feet (6.1 meters) of #6 AWG electrode cable • Fifteen feet (4.
D-1 MAINTENANCE D-1 SAFETY PRECAUTIONS • Have qualified personnel do all maintenance and troubleshooting work. • Turn the engine off before working inside the machine. • Remove guards only when necessary to per- form maintenance and replace them when the maintenance requiring their removal is com- plete.
