When the remote start signal quits, the unit will go through the stop delay, then stop.
The unit then proceeds to enter the wire retract time, pulling the wire out of the weld zone.
This action prevents the wire from sticking in the weld puddle at the end of the weld.
Note: If the retract time is set too long, the wire could retract up into the wire tip. If this
happens, the wire could, on occasion, get stuck on the tip on the next weld.
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 position.
When wire is no longer required the operator 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” adjustment of tip on each s ide 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 approximate
position.
The wire position should be checked at the beginning 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.
