Lincoln Electric IM751 POWER-ARC 4000 - Manual (Page 23)

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. Refer to Figure 3 to see the circuit. See
“Cable Installation” section for proper cable connec-
tion 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 2 “Welding
Application Chart” 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.
Stick Welding
Semi-automatic, MIG Welding With a
Lincoln Weld Pak 100 or Weld Pak 125
The Power-Arc generator power can be used to supply
power to a Lincoln Weld-Pak 100 or Weld-Pak 125 wire
feed welder. The Weld-Pak is equipped with all the
supplies needed for Flux-Cored Arc Welding (FCAW),
and is available where Lincoln products are sold.
A K610-1 MIG Conversion Kit is also available for the
Weld-Pak which provides all the essentials needed for
Gas Metal Arc Welding, GMAW, or MIG processes.
