REMOTE SENSE LEAD SPECIFICATIONS
Welding with Multiple Arcs:
( See Figure A.6)
Special care must be taken when more than one arc is welding
simultaneously on a single part. Arc blow and arc interference
may occur or be magnified. Each power source requires a work
lead from the work stud to the welding fixture. Do not combine all
of the work leads into one lead. Performing welding in the direc-
tion away from the work leads. Connect all of the work sense
leads from each power source to the work piece at the end of the
weld, such that they are out of the path of the weld current. See
Figure A.6
For the best results when pulse welding, set the wire size and
wire feed speed the same for all the arcs. When these parameters
are identical, the pulsing frequency will be the same, helping to
stabilize the arcs.
LOADING SPOOLS OF WIRE
• Keep hands, hair, clothing and tools away from
rotating equipment.
• Do not wear gloves when threading wire or
changing wire spool.
• Only qualified personnel should install, use or
service this equipment.

Loading 10 to 15 lb. (4.5 – 6.8kg) Spools.
A K468 spindle adapter is required for loading 2" (51mm) wide
spools on 2" (51mm) spindles. Use a K468 spindle adapter for
loading 2-1/2" (64mm) wide spools.
1. Squeeze the release bar on the retaining collar and remove it
from the spindle.
2. Place the spindle adapter on the spindle, aligning the spindle
brake pin with the hole in the adapter.
3. Place the spool on the spindle and align the adapter brake tab
with one of the holes in the back side of the spool. An indicator
mark on the end of the spindle shows the orientation of the
brake tab. Be certain the wire feeds off of the spool in the
proper direction.
4. Re-install the retaining collar. Make sure that the release bar
snaps out and that the retaining collar fully engages the groove
on the spindle.
