WELDING WITH MULTIPLE POWER WAVES

CAUTION

Special care must be taken when more than one Power Wave 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. The welding travel direc- tions should be in the direction moving away from the work lead as shown below. Connect all of the work sense leads from each power source to the work piece at the end of the weld.

For the best results when pulse welding, set the wire size and wire feed speed the same for all the Power Waves.

When these parameters are identical, the pulsing fre- quency will be the same, helping to stabilize the arcs.

Every welding gun requires a seperate 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.)
