Electrode Voltage Sensing | | |
The remote ELECTRODE sense lead (67) is built into the 5-pin arclink control cable and is always connect- ed to the wire drive feed plate when a wire feeder is present. Enabling or disabling electrode voltage sens- ing is application specific, and automatically config- ured 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 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 fea- ture there are no set-up requirements for welding with negative electrode polarity. This feature can be dis- abled 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).
CAUTION
If the auto sense lead feature is disabled and the weld polarity attribute is improperly configured extremely high welding outputs may occur.
