7. If the unit is used manually, the operator
will press the Start button when ready to
feed wire. The start delay will NOT be
activated when using this method. Wire
will feed immediately once in the Run

When wire is no longer required the op-
erator presses the Stop button. The unit
will stop feeding wire immediately and
go into the wire retract procedure.
C. Wire Guide Positioner
Several adjustments are provided on the wire
guide positioner in order to permit the exact
position of the wire as it enters the puddle.
1.
Lateral adjustment of 1/4” (1/8” adjust-
ment of tip on each side of weld seam).
(6.4 mm total adjustment, 3.2 mm on
each side.)
2. Vertical adjustment of 1/4” (6.4 mm) tip
to work.
3. Coarse adjustment of guide tip angle, by
loosening screw and setting in approxi-
mate position.
The wire position should be checked at the be-
ginning of the weld.
Jog the wire forward through the control and
make required adjustments on the positioner.
Wire typically enters the weld puddle at the
leading edge of the puddle. The wire should
contact the work piece about .04” (1 mm) in
front of the weld puddle and slide under the
center of the welding arc.
Check tension of drive roll spring. Too much
pressure will deform the wire and too little
pressure will cause wire slippage.
