Lincoln BULLDOG 140, Operator'S Manual

Page: 22 / 46

Stick welding is probably the most familiar welding
process known. A coated ELECTRODE, the weld rod,
is clamped into an ELECTRODE HOLDER, an insulat-
ed clamping device, which in turn connects to the
ELECTRODE CABLE, a heavy wire. The WORK, the
metal piece to be welded, is connected to the WORK
CABLE, a heavy wire which contains the WORK
CLAMP. Quality Lincoln cables use many fine copper
wires with a very flexible insulating covering for the
electrode and work cables. When properly connected
to the OUTPUT STUDS of a high current power
source, the electrode melts and bonds the metal being
repaired. See “Cable Installation” section for proper
cable connection to a Power-Arc.
The Power-Arc provides excellent weld output charac-
teristics when used in combination with Lincoln AC
electrodes. Other AC electrodes may also be used.
Follow the settings listed in Table B.2 “Welding
Application Guide” and the “Electrode Selection
Guide” found on the nameplate of the machine.
ARC RAYS can burn.
• When using an open arc process,
it is necessary to use correct eye,
head and body protection.

Wire Feeder/Welders come equipped with the essen-
tials needed for Gas Metal Arc Welding, GMAW, or
MIG processes, while others require the purchase of a
conversion kit. These products are available where
Lincoln products are sold. Contact your local autho-
