Feeding Electrode and Brake Adjustment
1) Turn the Readi-Reel or spool until the free end of
the electrode is accessible.
WARNING
When feeding with the gun energized, the electrode
and drive mechanism are always “HOT� to work and
ground and could remain “HOT� several seconds after
the gun trigger is released.
___________________________________________
2) While tightly holding the electrode, cut off the bent
end and straighten the first 6� (150mm). Cut off the
first 1� (25mm). (If the electrode is not properly
straightened, it may not feed or may not go into the
outgoing guide tube causing a “birdnest�.)
3) Insert the free end through the incoming guide tube.
4) Press the Cold Inch key or the 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 lit-
tle or no overrun when wire feeding is stopped. Do
not overtighten.

� Only Qualified personnel should
perform this maintenance.
� Turn the input power OFF at the
disconnect switch or fuse box
before working on this equipment.
� Do not touch electrically hot parts.
ROUTINE AND PERIODIC
MAINTENANCE
Perform the following preventive maintenance at least
once every six months.
WARNING
Prior to performing preventive maintenance it is impor-
tant to perform the following capacitor discharge pro-
cedure to avoid electric shock.
INPUT FILTER CAPACITOR DIS-
CHARGE PROCEDURE
1. Turn off input power and disconnect input power
lines.
2. Remove the hex head screws from the top and the
sides of the machine. Remove the handle bar and
the wrap-around machine cover.
3. Remove the two case sides. There are hex head
screws on each side.
CAUTION
TO PREVENT DAMAGE TO MACHINE, AVOID
UNNECESSARY MOVEMENT OF FRONT PANEL.
4. Obtain a high resistance and high wattage resistor
(25-1000 ohms and 25 watts minimum). This
resistor is not supplied with the machine. Secure
this resistor to a piece of insulating material such
as a glastic board. See Figure D.3. NEVER USE A
SHORTING STRAP FOR THIS PROCEDURE.

5. Locate two sets of two resistors on the left side of
the machine and three sets of two resistors on the
right side of the machine. See Figure D.1. Do not
touch the resistors or any other internal machine
component. Using a DC voltmeter, check for any
DC voltage that may be present across the termi-
nals of each resistor and from each resistor to
case ground (20 measurements in all). If a voltage
is present, be careful not to touch these resistors.

7. Using insulated, needle nose-type jumper leads
and insulated gloves, connect one jumper lead to
one end of the resistor obtained in step 4.
Connect the other jumper lead to the other end of
the resistor.
8. Carefully connect the needle nose end of one of
the jumper leads to terminal #9. See Figure D.3.
Connect the needle nose end of the other jumper
lead to terminal #12. Terminals #9 and #12 are
indicated by the “Discharge� label. Leave resistor

7. Remove welding cables and check the electrical
ground continuity. Use an ohmmeter to measure
the resistance between each output terminal and
an unpainted surface of the machine case. The
meter reading should be 500,000 ohms or more. If
the meter reading is less than 500,000 ohms,
check for electrical components that are not prop-
