CIRCUIT PROTECTION
Circuit Breaker – The 3.5 amp circuit breaker located
on the rear of the unit normally trips only when an over-
load occurs because of excessive loading in the wire
feed cable or a defective motor or control components.
After allowing a few minutes for cooling, push the reset
button and weld. If it trips again, be sure the gun cable
is not being excessively bent, is clean, and is the prop-
er size for the wire diameter being fed. If it still trips,
look for a defective electrical component.
NAMEPLATES
Whenever routine maintenance is performed on this
machine — or at least yearly — inspect all nameplates
and labels for legibility. Replace those which are no
longer clear. Refer to the parts list for the replacement
item number.
