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.
• Loose connections will cause the output terminals to
overheat. The terminals may eventually melt.
• Do not cross the welding cables at the output termi-
nal connection. Keep the cables isolated and sepa-
rate from one another.
Lincoln Electric offers a welding accessory kit with the
properly specified welding cables. See the ACCES-
SORIES section of this manual for more information.
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 electri-
cal 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.
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 vehi-
cle. See Figure A.1. The ground stud is
marked with the symbol.
PLUGS AND HAND-HELD EQUIPMENT
For further protection against electric shock, any elec-
trical equipment connected to the generator recepta-
cles 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 manu-
al for details.
If you need ground fault protection for hand-held
equipment, in-line ground fault current interrupter
(GFCI) cord sets that meet UL and OSHA require-
ments are available from:
Ericson Manufacturing Company
Willoughby, Ohio 44094
(216) 951-8000 (Ohio)
1-800-972-5109 (outside Ohio)
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) receptacle.
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. The machine output volt-
ages meet UL standards and fall within ± 10% of the
rated voltage. The output frequency falls within ± 3%
of rated frequency (60 Hz).
