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.
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
®
S350 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).
If the auto sense lead feature is disabled and the weld
polarity attribute is improperly configured extremely high
welding outputs may occur.
