Electrode Voltage Sensing
The remote ELECTRODE sense lead (67) is built into the 5-pin
arclink control cable and is always connected to the wire drive
feed plate when a wire feeder is present. Enabling or disabling
electrode voltage sensing is application specific, and automatically
configured by the active weld mode.
If the auto sense lead feature is disabled and the weld
polarity attribute is improperly configured extremely high
welding outputs may occur.
Work Voltage Sensing
While most applications perform adequately by sensing the work
voltage directly at the output stud, the use of a remote work
voltage sense lead is recommended for optimal performance. The
remote WORK sense lead (21) can be accessed through the four-
pin voltage sense connector located on the control panel by using
the K940 Sense Lead Kit. It must be attached to the work as close
to the weld as practical, but out of the weld current path. For more
information regarding the placement of remote work voltage
sense leads, see in this section entitled "Voltage Sensing
Considerations for Multiple Arc Systems."
Negative Electrode Polarity
The POWER WAVE® S500 has the ability to automatically sense
the polarity of the sense leads. With this feature there are no set-
up requirements for welding with negative electrode polarity. This
feature can be disabled through the Weld Manager Utility
(available at www.powerwavesoftware.com) or through the set up
menu (if a user interface is installed into the power source).
