A-6 INSTALLATION
POWER-ARC 5500
A-6
Cable Installation
Install the welding cables to your POWER-ARC 5500
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
5500 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.
• L Loose c connections w will c cause tthe o output ttermi-
nals tto o overheat. T The tterminals m may e eventually
melt.
• D Do n not c cross tthe w welding c cables a at tthe o output
terminal c connection. K Keep tthe c cables iisolated
and s separate ffrom o one a 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 5500 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.
Do n not g ground tthe m machine tto a a p pipe tthat c carries
explosive o or c combustible m material.
When the POWER-ARC 5500 is mounted on a truck
or a trailer, the machine generator
ground stud MUST be securely connect-
ed 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.
Ground fault protection is needed for hand held
equipment.
Never operate this machine with damaged or
defective cords. All electrical equipment must be
in safe condition.

AUXILIARY POWER RECEPTACLES
The control panel of the POWER-ARC 5500 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 5,500 surge
watts of single-phase AC power.
