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.

3.Connect the electrode holder and work cables to the weld output terminals. You can connect either cable to either terminal, since the POWER- ARC 4000 provides AC weld current.

4.Tighten the flanged nuts securely.

5.Be certain that the metal piece you are welding (the “work”) is securely connected to the work clamp and cable.

6.Check and tighten the connections periodically.

CAUTION

•Loose connections will cause the output termi- nals to overheat. The terminals may eventually melt.

•Do not cross the welding cables at the output terminal connection. Keep the cables isolated and separate from one another.

Lincoln Electric offers a welding accessory kit with the properly specified welding cables. See the ACCESSORIES section of this manual for more infor- mation.

MACHINE GROUNDING

Because the POWER-ARC 4000 creates its own power from its gasoline-engine driven generator, you do not need to connect the machine frame to an earth ground. However, for best protection

against electrical shock, connect a heavy gauge wire from the ground stud located on the bottom center of the output panel (see Figure A.1) to a suitable earth ground such as a metal pipe driven into the ground.

WARNING

Do not ground the machine to a pipe that carries explosive or combustible material.

When the POWER-ARC 4000 is mounted on a truck or a trailer, the machine gen- erator ground stud MUST be securely connected to the metal frame of the vehicle. See Figure A.1. The ground stud is marked with the symbol.

PLUGS AND HAND-HELD EQUIPMENT

For further protection against electric shock, any electrical equipment connected to the generator receptacles must use a three-blade, grounded type plug or an Underwriter’s Laboratories (UL) approved double insulation system with a two-blade plug. Lincoln offers an accessory plug kit that has the right type of plugs. See the ACCESSORIES section of this manual for details.

Ground fault protection is needed for hand held equipment.

WARNING

Never operate this machine with damaged or defec- tive cords. All electrical equipment must be in safe condition.

AUXILIARY POWER RECEPTACLES

The control panel of the POWER-ARC 4000 features two auxiliary power receptacles:

•A 20 amp, 120 volt duplex (double outlet) recepta- cle

•A 20 amp 240 volt simplex (single outlet) recepta- cle.

See Figure A.1.

Through these receptacles the machine can supply up to 4,000 rated continuous watts and 4,400 surge watts of single-phase AC power.
