WIRE INSTALLATION
NOTE: Before installing welding wire,
be sure:
a. Diameter of welding wire matches
groove in drive roller on wire feed
mechanism (See Fig. 2). The drive
roller is marked with metric sizes:
.6mm = .024", .8 - .9mm = .030 –
.035"
b. Wire matches contact tip in end of
gun. (See Fig. 3).
A mismatch on any item could cause the
wire to slip and bind.
NOTE: Always maintain control of loose
end of welding wire to prevent
unspooling.
1. Verify unit is off and open door
panel to expose wire feed
mechanism.
2. Remove the spool quick lock by
pushing in and rotating 1/4 turn
counterclockwise. Then remove
knob, spring and spool spacer.
3. Flip tensioning screw down on drive
mechanism. This allows initial
feeding of wire into gun liner by
hand.
4. Install wire spool onto spindle so
wire can come off spool on the end
closest to the wire feed guide tube.
Do not cut the wire loose yet.
Install spool spacer, spring and quick
lock knob by pushing in and turning
knob 1/4 rotation clockwise.
5. Hold wire and cut the wire end from
spool. Do not allow wire to
unravel. Be sure end of wire is
straight and free of burrs.
6. Feed wire through wire feed guide
tube, over the groove in drive roller
and into gun liner. Flip tensioning
screw up and adjust tension by rotating
tensioning screw knob. Do not
overtighten.
7. Remove nozzle by turning counter-
clockwise, then unscrew contact tip
from end of welding torch (See
Figure 3). Plug welder into a proper
power supply receptacle.
8. Turn on welder and set wire speed
rate to 10. Activate gun trigger until
wire feeds out past the torch end.
Turn welder off.
9. Carefully slip contact tip over wire
and screw tip into torch end. Install
nozzle by turning clockwise (See
Figure 3). Cut wire off approximately
1/4 inch from nozzle end.
