WORK CLIP LEAD

WARNING

ELECTRIC SHOCK can kill.

Do not touch metal por- tions of the LN-35 lead clip when welding power source is on.

WARNING

IMPORTANT SAFETY NOTE: To avoid possible electrical shock, do not touch the metal portions of the LN-35 work lead clamp if the power source output is on. The clamp will be electrically “HOT” to work if the input electrode cable to the LN-35 is electrically “HOT” even if the gun trigger is off. Care should be taken to only handle the LN-35 work clamp by its non-metal insulated portions and/or the welding power source should be turned off before handling the work clamp.

--------------------------------------------------------------------

The 15 ft work clamp lead attached to the front panel of the LN-35 case must be connected directly to the work using the spring clamp on the end of the lead.

If not connected, the LN-35 will not operate. However, the electrode will still be electrically “HOT” when the clamp lead is disconnected.

WIRE REEL LOADING – 50 AND 60 LB

ADJUSTABLE WIRE REEL BRAKE

The mount for standard 50 and 60 pound electrode coils includes a two - position brake assembly . Generally the brake should be at the inner position (nearest to the wire reel shaft) for wire feed speeds below 400 in./min (10 m/min). It should be at the outer position for the faster wire speeds often used when feeding smaller diameter electrode.

To adjust the brake position, remove the wire reel. Pull the cotter pin that holds the brake shoe to the arm, move the shoe and replace the cotter pin. Do not bend the cotter pin - it is held in place by a friction fit.

TO MOUNT A 50 OR 60 LB COIL:

1.To remove the wire reel from its shaft.

2.Lay the reel flat on the floor. Loosen the spinner nut and remove the cover plate. See Figure B.1.

3.Place the coil of electrode on the reel so it unwinds as the reel rotates clockwise. DO NOT cut the tie wires at this time.

4.Be sure the coil is placed so the spring loaded arms will not interfere with the later removal of the coil tie wires.

5.When loading 0 . 030, 0 . 035, and 0 . 045” electrode, be certain the coil is placed on the reel so the spring loaded arms are at the center of the slots in the cardboard coil liner. This provides the positive compression of the coil sides needed for trouble-free wire feeding.

6.Put the cover plate on the reel so the four arms of the cover plate straddle and are in line with the spring loaded arms of the reel.

7.Tighten the cover as much as possible by hand.

CAUTION

DO NOT hammer on the spinner nut arms. Always be sure the free end of the coil is securely held while the tie wires are being cut and until the wire is feeding through the drive rolls. Failure to do this will result in “back lashing” of the coil, which may tangle the wire. A tangled coil will not feed. It must be untangled or discarded.

-------------------------------------------------------------------

8.Cut and remove only the tie wire holding the free end of the coil. Insert the free end into one of the holes in the cover and secure it by bending it back. Cut and remove the remaining tie wires.

9.Replace the reel on the wire feeder.
