D-2 MAINTENANCE
LN™-23P
D-2
CIRCUIT PROTECTION
Circuit Breaker – The 3.5 amp circuit breaker located
on the rear of the unit normally trips only when an
overload occurs because of excessive loading in the
wire feed cable or a defective motor or control compo-
nents. 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 proper 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 name-
plates and labels for legibility. Replace those which
are no longer clear. Refer to the parts list for the
replacement item number.
POWER SOURCE
One or two LN™-23P’s can be connected to a DC power source (constant voltage) with a K350-1 Adapter Kit. If
two LN™-23P’s are connected, they can be set for different procedures but only one can be used at a time.
NOTE: The K350 must be used on power sources with terminal strip connections only.
