LOADING WIRE DRIVE

a. Turn the reel or spool until the free end of the electrode is accessible.

b. While tightly holding the electrode, cut off the bent end and straighten the first six inches. Cut off the first inch. (If the electrode is not properly straightened, it may not feed or may not go into the outgoing guide tube causing a “birdnest”.)

c. Insert the free end through the incoming guide tube to the drive roll.

d. Turn on the welding power source.

f.Inch the electrode through the gun.

g.Adjust the brake tension with the thumbscrew on the spindle hub until the reel turns freely, but with little or no overrun when wire feeding is stopped. Do not overtighten.

CAUTION

Keep gun in LN-25 gun holder when not feeding wire to prevent accidental arcing.

WARNING

IDLE ROLL PRESSURE SETTING

 

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.

e. Press the gun trigger and push the electrode until it just enters the drive roll.

WARNING

When inching with gun trigger, the electrode and drive mechanism are always “hot” to work and ground. Use the “cold” inch switch on models with internal contactor.

The idle roll pressure is set at the factory backed out two turns from full pressure. This is an approximate setting. For small wire sizes and aluminum wire, the optimum idle roll pressure varies with type of wire, surface condition, lubrication and hardness. The op- timum idle roll setting can be determined as follows:

1.Press end of gun against a solid object that is electrically isolated from the welder output. Press the gun trigger for several seconds.

2.If the wire “birdnests,” jams or breaks at the drive roll, the idle roll pressure is too great. Back the pressure setting out 1⁄2 turn, run new wire through gun, and repeat above steps.
