Caution: The machine may appear to operate with an incorrectly connected ground
wire, but it will not operate properly. Selecting the correct ground wire is important
for proper machine operation and personnel safety.
Ground wires on LONGEVITY® Welding machines are usually one of the following
colors:

The ground wire is a dark green with a yellow stripe. The wire may also be just
SOLID GREEN.
Clean the ends of the wires to more easily distinguish the colors. The best and safest
way to determine which wire is ground is to measure the resistance between the
machine chassis and the selected wire, using an ohmmeter. Another method is to
check the continuity between the chassis and the wire, using a continuity meter. If
the selected wire is ground, the connection between the chassis and the wire will
cause the meter to illuminate. If, for any reason, you cannot visually detect the
ground wire or do not feel comfortable with your selection, ask an electrician for
help.
