Figure 3. Drive Brake Assembly
Adjust the drive brake tension. The
purpose of the drive brake is to
cause the spool of wire to stop
turning at nearly the same moment
that wire feeding stops.
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, or the wire will unspool
itself.
Using a wire cutter, cut the bent end
off the leading end of the wire so
that only a straight leading end
remains.
Hold the tension arm up off the
drive roller and insert the leading
end of the wire into the inlet guide
tube. Then push it across the drive
roller and into the gun assembly
about six inches.
Line the wire up in the outside
groove of the drive roller, then allow
the drive tension arm to drop onto
the drive roller.
Tighten (turn clockwise) the tension
adjusting screw until the tension
roller is applying enough force on
the wire to prevent it from slipping
out of the drive assembly.
