1) Turn the Reel or spool until the free end of the
electrode is accessible.
2) While tightly holding the electrode, cut off the bent
end and straighten the first 6" (150 mm). Cut off
the first 1" (25 mm). (If the electrode is not proper-
ly straightened, it may not feed or may jam causing
a "birdnest".)
3) Insert the free end through the incoming guide
tube.
4) Press the Cold Inch key or the Cold Feed Mode
gun trigger and push the electrode into the drive
roll.

5) Feed the electrode through the gun.
6) 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.

The Power Feed 10 Dual Wire Feeder pressure is fac-
tory pre-set to about position “2" as shown on the
pressure indicator on the front of the feedplate door.
This is an approximate setting.
The optimum drive roll pressure varies with type of
wire, surface condition, lubrication, and hardness.
Too much pressure could cause “birdnesting”, but too
little pressure could cause wire feed slippage with
load and/or acceleration. The optimum drive roll set-
ting can be determined as follows:
1) Press end of gun against a solid object that is
electrically isolated from the welder output and
press the gun trigger for several seconds.
2) If the wire "birdnests", jams, or breaks at the drive
roll, the drive roll pressure is too great. Back the
pressure setting out one turn, run new wire through
gun, and repeat above steps.
3) If the only result is drive roll slippage, disengage
the gun, pull the gun cable forward about 6" (150
mm). There should be a slight waviness in the
exposed wire. If there is no waviness, the pres-
sure is too low. Increase the pressure setting one
turn, reconnect the gun, tighten locking clamp and
repeat the above steps.

1) Loosen the clamping collar screw using a 3/16"
Allen wrench. The clamping collar screw is
accessed from the bottom of the feedplate. It is
the screw which is perpendicular to the feeding
direction.
2) Rotate feedplate to the desired angle and tighten
clamping collar screw.

1) With the gas supply shut off, the Gas Guard regu-
lator flow adjusting Key should be set to maximum
(full clockwise) which is rated to be 60 SCFH (28
l/min).
2) Adjust gas supply flow rate for a level higher than
will be required, then adjust Gas Guard flow
adjusting Key counterclockwise to the desired gas
flow rate.
