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.(See Figure A.6)
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 frequency 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.

CONTROL CABLE SPECIFICATIONS
It is recommended that genuine Lincoln control cables be used at all times. Lincoln cables are specifically designed for the communication and power needs of the Power Wave / Power Feed system.
CAUTION
The use of
The K1543 series of control cables can be connected end to end for ease of extension. Do not exceed more than 100 feet (30.5 m) total control cable length.
