POWER-ARC 4000
Stick welding is probably the most familiar welding
process known. A coated ELECTRODE, the weld
rod, is clamped into an ELECTRODE HOLDER, an
insulated 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 char-
acteristics 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 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.
WARNING
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 process-
es.
Contact your local authorized Lincoln representative
for more details.
Learning To Stick Weld
The serviceability of a product or structure utilizing
this type of information is and must be the sole
responsibility of the builder/user. Many variables
beyond the control of The Lincoln Electric Company
affect the results obtained in applying this type of
information. These variables include, but are not limit-
ed to, welding procedure, plate chemistry and tem-
perature, weldment design, fabrication methods and
service requirements.
No one can learn to weld simply by reading about it.
Skill comes only with practice. The following pages
will help the inexperienced welder understand weld-
ing and develop his skill. For more detailed informa-
tion, order a copy of the book “New Lessons in Arc
Welding.”
(See Book Division section at rear of manual).
The operator’s knowledge of arc welding must go
beyond the arc itself. He must know how to control
the arc, and this requires a knowledge of the welding
circuit and the equipment that provides the electric
current used in the arc. The circuit begins where the
electrode cable is attached to the welding machine
and ends where the work cable cable is attached to
the machine. Current flows through the electrode
cable to the electrode holder, through the electrode
holder to the electrode and across the arc. On the
work side of the arc, the current flows through base
metal to the work cable and back to the welding
machine. The circuit must be complete for the current
to flow. To weld, the work clamp must be tightly con-
nected to clean base metal. Remove paint, rust,etc.
as necessary to get a good connection. Connect the
work clamp as close as possible to the area you wish
to weld. Avoid allowing the welding circuit to pass
through hinges, bearings, electronic components or
similar devices that can be damaged.
