OPERATION

B-4

 

 

 

Note: The brake should be adjusted with a spool of wire installed. When properly adjusted it should move freely but not coast.

Friction Brake Adjustments

1.With wire spool installed, check free movement and coast of the spool.

2.To tighten the brake turn the wing nut clockwise in 1/4 turn increments until coasting stops.

3.To loosen the brake turn the wing nut counter- clockwise in 1/4 turn increments until the wire spool moves freely without coasting.

Wire Threading

Refer to Figure B-4

1.Release the Spring Loaded Pressure Arm (1) rotate the Idle Roll Arm (2) away from. the Wire Feed Drive Roll (3). Ensure that the groove size in the feeding position on the drive roll matches the wire size being used.

2.Carefully detach the end of the wire from the spool. To prevent the spool from unwinding, maintain tension on the wire until after step 5.

3.Cut the bent portion of wire off and straighten the first 4” (100 mm).

4.Thread the wire through the In-going guide tube (4), over the drive roll (3), and into the out-going guide tube (5).

5.Close the idle roll arm and latch the spring loaded pressure arm (2) in place . Rotate the spool coun- terclockwise if required in order to take up extra slack in the wire.

WARNING

When inching the welding wire, the drive rolls, the gun connector block and the gun contact tip are electrically energized relative to work and ground and remain energized for several seconds after the gun trigger is released.

6.The idle roll pressure adjustment wing nut is nor- mally set for mid-position on the pressure arm threads. If feeding problems occur because the wire is flattened excessively, turn the pressure adjustment counter-clockwise to reduce distortion of the wire. Slightly less pressure may be required when using 0.023 – 0.025” (0,6 mm) wire. If the drive roll slips while feeding wire, the pressure should be increaseduntil the wire feeds properly.

The Wire Drive Feed Roll can

accommodate two wire sizes by

flipping the wire drive feed roll over.

7.Refer to Figure B.5. Remove gas nozzle and con- tact tip from end of gun.

8.Turn the PRO 100 ON (“I”).

9.Straighten the gun cable assembly.

10.Depress the gun trigger switch and feed welding wire through the gun and cable. (Point gun away from yourself and others while feeding wire.) Release gun trigger after wire appears at end of gun.

11.Turn the PRO 100 OFF (“O”).

12.Replace contact tip and gas nozzle.

13.Refer to Figure B-6. Cut the wire off 1/4” – 3/8” (6

– 10 mm) from the end of the tip. The PRO 100 is now ready to weld.
