POWER MIG 260
To Mount 10 to 44 Lb. (4.5-20 kg) Spools (12"/300
mm Diameter) or 14Lb.(6 Kg) Innershield Coils:
(For 13-14 lb. (6 Kg) Innershield coils, a K435 Coil Adapter must
be used).
(For 10 lb.(4.5 Kg) 8 inch(203mm) diameter spools, a K468
spindle adapter must be used).
1. Open the Wire Drive Compartment Door.
2. Depress the Release Bar on the Retaining Collar and remove it
from the spindle.
3. Place the spool on the spindle making certain the spindle brake
pin enters one of the holes in the back side of the spool (Note:
an arrow mark on the spindle lines up with the brake holding
pin to assist in lining up a hole). Be certain the wire comes off
the reel in a direction so as to de-reel from the top of the coil.
4. Re-install the Retaining Collar. Make sure that the Release Bar
"pops up" and that the collar retainers fully engage the
retaining ring groove on the spindle.

TO START THE WELDER

Turn the "Power Switch" switch to "ON". This lights the red LED
display lights. With the desired voltage and wire speed selected,
operate the gun trigger for welder output and to energize the wire
feed motor.

FEEDING WIRE ELECTRODE

WARNING
When triggering, the electrode and drive mechanism are
electrically "hot" relative to work and ground and remain
"hot" several seconds after the gun trigger is released.
NOTE: Check that drive rolls, guide plates and gun parts are
proper for the wire size and type being used. Refer to Table C.1 in
Accessories section.
1. Turn the Readi-Reel or spool until the free end of the electrode
is accessible.
2. While securely holding the electrode, cut off the bent end and
straighten the first six inches. (If the electrode is not properly
straightened, it may not feed properly through the wire drive
system).
3. Release the pressure on the idle roll by swinging the adjustable
pressure arm down toward the back of the machine. Lift the
cast idle roll assembly and allow it to sit in an upright
position. Leave the outer wire guide plate installed. Manually
feed the wire through the incoming guide bushing and
through the guide plates (over the drive roll groove). Push a
sufficient wire length to assure that the wire has fed into the
gun and cable assembly without restriction. Reposition the
adjustable pressure arm to its original position to apply
pressure to the wire.
4. Press gun trigger to feed the electrode wire through the gun.

IDLE ROLL PRESSURE SETTING

WARNING
ELECTRIC SHOCK can kill.
• Turn the input power OFF at the welding
power source before installation or changing
drive rolls and/or guides.
• Do not touch electrically live parts.
• When inching with the gun trigger, electrode and drive
mechanism are "hot" to work and ground and could
remain energized several seconds after the gun trigger
is released.
• Only qualified personnel should perform maintenance
work.
The pressure arm controls the amount of force the drive rolls exert
on the wire. Proper adjustment of both pressure arm gives the
best welding performance. For best results, set both pressure
arms to the same value.
Set the pressure arm as follows (See Figure B.4):
