SEQUENCE OF OPERATION

LOADING ELECTRODE

WARNING

ELECTRIC SHOCK can kill.

•Unless an optional output control or internal contactor is used with the LN-25, the electrode circuit is electrically “Hot” when the power source is on.

•Turn off the power source while mounting electrode coils.

MOUNTING 22 TO 30 LB READI-REEL®COILS

The LN-25 will require an optional K363-P Readi- Reel® Adapter which is required to load Lincoln 22 to 30 lb Readi-Reel coils.

a. Make certain that the threaded locking collar is tight and securely locks the adapter on the spindle (see figure B.2).

b. Rotate the spindle and adapter so the retaining spring is at the 12 o’clock position.

c.Position the Readi-Reel so that it will rotate in a clockwise direction when feeding (wire is to be dereeled from bottom of the coil).

d.Set one of the Readi-Reel inside cage wires on the slot in the retaining spring tab.

e.Lower the Readi-Reel to depress the retaining spring and align the other inside cage wires with the grooves in the molded adapter.

f.Slide cage all the way onto the adapter until the retaining spring “pops up” fully.

WARNING

Check to be sure the retaining spring has fully returned to the locking position and has securely locked the Readi-Reel cage in place. Retaining spring must rest on the cage, not the welding electrode.

g.To remove Readi-Reel from Adapter, depress re- taining spring tab with thumb while pulling the Readi-Reel cage from the molded adapter with both hands . It is not necessary to remove adapter from spindle.

h.Load wire into wire drive per Loading Wire Drive Section.

MOUNTING 10 TO 30 LB SPOOLS

For 12” Diameter Spools:

a. Remove the locking collar and the Readi-Reel adapter (if so equipped) on the 2” diameter spindle (adapter is not required).

b. Place the spool on the spindle so the brake holding pin enters one of the holes in the back side of the spool. Be sure the wire comes off the spool in a clockwise direction when dereeled from the bottom of the coil.

c. Replace and tighten the locking collar.

d. See Loading Wire Drive section for loading instructions.

For 8” Diameter Spools (Requires optional K468 Spindle Adapter for 8” Spools):

a. Remove the locking collar and the Readi-Reel adapter (if so equipped) on the 2” diameter spindle (adapter is not required).

b. Slide S18221 Spindle Adapter onto the 2” spindle so the brake holding pin enters the adapter pin hole.

c.Place the spool on the spindle so the adapter tab enters one of the holes in the back side of the spool. Be sure the wire comes off the spool in a clockwise direction when dereeled from the bottom of the coil.

d.Replace and tighten the Locking Collar.

e.Load wire into wire drive per Loading Wire Drive Section.

MOUNTING 13 OR 14 LB INNERSHIELD COILS (Requires Optional K435 Spindle Adapter for 14 lb Coils.)

a. Remove the locking collar and the Readi-Reel adapter (if so equipped) on the 2” diameter spindle (adapter is not required).

b. Mount K435 Spindle Adapter and Innershield coil per the Instructions (S18256) included with the

LN-25 K435.
