WELDING WITH MULTIPLE ARCS

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. Always weld in a 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 weld, such that they are out of the path of the weld current.

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 fre- quency will be the same, helping to stabilize the arcs.

If the voltage sensing is enabled but the sense leads are missing, improperly connected, or if the electrode polarity switch is improperly configured extremely high welding outputs may occur.

In extremely sensitive applications requiring voltage sense leads, it may be necessary to route cables that contain the sense leads away from the electrode and work welding cables. For more information regarding the placement of voltage sense leads, see the section entitled "Welding with Multiple Independent Power Waves."
