5-23. Voltage Sensing Lead And Work Cable Connections For Multiple Welding Arcs
A. Ideal Setup
805 289-B
1 Welding Power Source
2 Composite Cable
3 Work Cable
4 Volt Sense Lead
The volt sense lead must be used to
provide an accurate voltage feedback
signal to the welding system. Use of this
lead is critical for stable welding
performance.
5 Wire Feeder
6 Workpiece
This arrangement is an ideal setup for
supporting separate voltage feedback to
the welding power sources. The most
accurate voltage sensing may not be
achieved due to voltage drops in the
workpiece. This may require
compensation in the welding parameters.
