• Always turn the power switch to the OFF position and unplug the welder’s power
cord from the AC power source before installing wire.
1. Remove the nozzle and contact tip from the end of the gun assembly.
2. Release the wire tension arm by flipping the drive tension knob out. Move the wire tension
arm up and away from the drive roller.
3. Make sure that the wire diameter stamped on the
drive roller is the same as the diameter of the wire
being installed. If it is not the same, change the
drive roller as specified in the preceding section.
4. Remove the wire spindle spring/spool tension
hardware to allow the spool to be mounted.
5. Unwrap the spool of wire and find the leading end
of the wire (it goes through a hole in the outer
edge of the spool, and is bent over the spool
edge to prevent the wire from unspooling), but do
not unhook it yet!
6. Place the spool on the spindle in such a manner
that when the wire comes off the spool, it enters
the wire drive assembly in a straight line (see
photograph)
7. After checking to make sure that your welder is
disconnected from the AC power source, free the
leading end of the wire from the spool, but do not
let go of it until told to do so in step 11, or the wire
will unspool itself.
WARNING
CUTTING WIRE CAN BE A HAZARD TO YOUR EYES.
• The end of the wire being cut can fly up at you - wear eye protection when cutting
wire.
8. Using a wire cutter, cut the bent end off the leading end of the wire so that only a straight
leading end remains.
9. With the wire tension arm pulled away from the drive roller, insert the leading end of the wire
into the inlet guide tube, push it across the drive roller and into the gun assembly, then hand
feed it about six inches into the gun.
10. Line the wire up in the groove of the drive roller, then rotate the wire tension arm to drop onto
the drive roller. Flip the tension-adjusting lever up and into place.
11. Tighten (turn clockwise) the drive tensioner knob until the drive-bearing roller is applying
enough force on the wire to prevent it from slipping out of the drive assembly. Now you can let
go of the wire.
12. Plug the welder's power cord into the AC power source, set the VOLTAGE selector to the
desired welding setting, and set the WIRE SPEED control to the middle of the wire speed
range.
