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.
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 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:
WARNING
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
Ground fault protection is recommended for hand held equipment.
WARNING
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
bULLDOG™ 5500
