Electrode Voltage Sensing
The remote ELECTRODE sense lead (67) is built into
the 5-pin arclink control cable (K1543-xx) 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 automati-
cally configured by the active weld mode.
Work Voltage Sensing
While most applications perform adequately by sens-
ing the work voltage directly at the output stud, the
use of a remote work voltage sense lead is recom-
mended 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 the section entitled "Voltage Sensing
Considerations for Multiple Arc Systems."
Negative Electrode Polarity
The POWER WAVE R350 has the ability to automati-
cally 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 Diagnostics Utility (available at
www.powerwavesoftware.com).
If the auto sense lead feature is disabled and the
weld polarity attribute is improperly configured
extremely high welding outputs may occur.
