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.

POWER SOURCE

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.

One or two LN™-23P’s can be connected to a DC power source (constant voltage) with a K-350 or 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.

LN™-23P/ Power Source Combinations

1.Classic II, Classic III, Classic IIID, or SA-250 with K350-1 Adapter Kit and K623-1 Wire Feed Module.

2.Commander 300, Commander 400 or Commander 500 with K350-1 Adapter Kit.

3.Ranger 250 , Ranger 275, or Ranger 305G with K350-1 Adapter Kit.

4.CV-300, CV305, CV-400, DC-400, DC-600, DC655 or V300, V350 Pro, V450 Pro with K350-1 Adapter Kit.

NOTE: The K350 must be used on power sources with terminal strip connections only.

K316L-2 may not require a K350-1 adapter if the power source has a Lincoln 14 pin connector.

5.SAE-400 or SAE-400 Weld ’N Air with K316L-2, K385-2 CV Adapter & K2379-1 Adapter Kit. NOTE: Only allows for one LN™-23P feeder.

Gun will always be HOT when SAE-400 is running.

6.SAE-400 with a K385-1 and a K350 Adapter.

NOTE: K350 wii have to be powered from 120VAC receptacle (customer responsibility). No remote control of weld voltage from LN™-23P

Gun will always be HOT when SAE -400 is running

7.LN™-23P (K316L-2) used with V350-Pipe does not require a K350-1 Adapter.
