Machine Grounding - Lincoln Electric WELDANPOWER 125 IM530-C Operator's Manual

Cable Installation
Install the welding cables to your Weldanpower 125
as follows. See Figure A.1 for the location of parts.
1. The gasoline engine must be OFF to install
welding 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. Normally, the electrode
cable is connected to the positive (+) output stud.
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 studs to
overheat and and the studs may eventually melt.
• Do not cross welding cables at output stud
connection. Keep isolated and separate from one
another.

INSTALLATION

MACHINE GROUNDING

Because this portable engine driven welder or
generator creates its own power, it is not necessary to
connect its frame to an earth ground, unless the
machine is connected to premises wiring (your home,
shop, etc.).
To prevent dangerous electric shock, other equipment
to which this engine driven welder supplies power,
must:
a) be grounded to the frame of the welder using a
grounded type plug
or
b) be double insulated
When this welder is mounted on a truck or trailer, the
machine grounding
connected to the metal frame of the vehicle.
Where this engine driven welder is connected to
premises wiring such as that in your home or shop, its
frame must be connected to the system earth ground.
See further connection instructions in the section
entitled Standby Power Connections as well as the
article on grounding in the latest U.S. National
Electrical Code and your local code.
In general if the machine is to be grounded, it should
be connected with a #8 or larger copper wire to a solid
earth ground such as a metal water pipe going into
the ground for at least ten feet and having no
insulated joints, or to the metal framework of a
building which has been effectively grounded. The
U.S. National Electrical Code lists a number of
alternate means of grounding electrical equipment. A
machine grounding stud marked with the symbol
is provided on the front of the welder.
DO NOT GROUND MACHINE TO A PIPE WHICH
CARRIES EXPLOSIVE OR COMBUSTIBLE
MATERIAL.
