Lincoln Electric BULLDOG IM10074 - Manual (Page 12)

A-5 INSTALLATION
BULLDOG™ 5500
A-5
Cable Installation
Install the welding cables to your BULLDOG™ 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 BULLDOG™
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.
• 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 ACCES-
SORIES section of this manual for more information.
ELECTRICAL CONNECTIONS
MACHINE GROUNDING
Because this portable engine driven welder creates its
own power, it is not necessary to connect its frame to
an earth ground, unless the machine is connected to
premises wiring (home, shop, etc.)
To prevent dangerous electric shock, other equipment
to which this engine driven welder supplies power
must:
1. Be grounded to the frame of the welder using a
grounded type plug.
2. Be double insulated.
Do not ground the machine to a pipe that carries
explosive or combustible material.
-----------------------------------------------------------------------
When the BULLDOG™ 5500 is mounted on a truck or
a trailer, the machine generator 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 elec-
trical equipment connected to the generator recepta-
cles must use a three-blade, grounded type plug or an
Underwriterʼs Laboratories (UL) approved double
insulation system with a two-blade plug.
Ground fault protection is recommended 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 BULLDOG™ 5500 features
these three auxiliary power receptacles:
• (Two) 20 amp, 120 volt duplex (double outlet)
receptacle.
• 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 5,500 surge watts
of single-phase AC power.
