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
The Power Wave® S350CE is configured at the facto-
ry to sense work voltage at the negative output stud
(positive output polarity with remote Work Voltage
Sensing disabled).
Negative Electrode Polarity
The Power Wave® S350CE has the ability to auto-
matically sense the polarity of the sense leads. With
this feature there are no set-up requirements for weld-
ing with negative electrode polarity. This feature can
be disabled through the Weld Manager Utility (avail-
able 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.
------------------------------------------------------------------------
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."
