WELDING WITH MULTIPLE Power
Waves
®
CAUTION
Special care must be taken when more than one
Power Wave ® is welding simultaneously on a sin-
gle 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 direction 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 joint.

INSTALLATION
For the best results when pulse welding, set the wire
size and wire feed speed the same for all the Power
Wave
When these parameters are identical, the pulsing fre-
quency will be the same, helping to stabilize the arcs.
Every welding gun requires a separate shielding gas
regulator for proper flow rate and shielding gas cover-
age.
Do not attempt to supply shielding gas for two or more
guns from only one regulator.
If an anti-spatter system is in use then each gun must
have its own anti-spatter system. (See Figure A.2.)
