OPERATION

FEEDING ELECTRODE AND bRAKE ADJUSTMENT

1.Turn the reel until the free end of the electrode is accessible.

2.While tightly holding the electrode, cut off the bent end. Straighten the first 6 inches.

3.Cut off the first inch. Insert the free end through the incoming guide tube.

4.Insert the free end through the incoming guide tube.

5.Press the gun trigger or “cold inch” (if used) and push the electrode into the drive roll. (If the elec- trode is not properly straightened, it may not feed or may not enter the outgoing guide tube, causing a "birdnest.")

6.Inch the electrode through the gun.

WARNING

USE THE "COLD" TRIGGER SWITCH POSITION, OR "COLD INCH" OPTION WHEN LOADING. WHEN INCHING WITH A "HOT" GUN TRIGGER, THE ELEC- TRODE AND WIRE FEEDING SYSTEM ARE ALWAYS "HOT" TO WORK AND GROUND AND COULD REMAIN "HOT" SEVERAL SECONDS AFTER THE GUN TRIGGER IS RELEASED.

LOADING AND FEEDING 13-14 Lb.

INNERSHIELD COILS (K378 REEL MOUNTING STAND)

The K378 small mounting stand for the 14 pound Innershield coil does not have an adjustable brake. It has a fixed drag built into the reel spindle.

To load a 14 pound coil:

1.Remove the snap-on lid from the plastic canister.

2.Remove the center clamping nut and the cover plate from the wire reel.

3.Unpack the 14-pound coil of wire. Be sure not to bend the side tangs of the coil liner. Straighten any tangs that may have been bent.

4.Remove the start end of the coil from its holding slot in the coil liner, cut off the bent end, straighten the first six inches, and cut off the first inch. (If the electrode is not properly straightened, it may not feed or may not go into the outgoing tube, causing a "birdnest.") Thread it through the canister wire feed liner until about four inches of electrode are exposed.

5.Place the coil onto the disc support.

6.Replace the front reel cover and center clamping nut, keep the reel from turning and tighten the clamping nut securely.

7.Thread the exposed end of the electrode into the wire feeder until it touches the drive rolls. Actuate the gun trigger, and feed the electrode through the system.
