WARNING
If the auto sense lead feature is disabled and remote
voltage sensing is enabled but the sense leads are
missing, improperly connected extremely high welding
outputs may occur.
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
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.
Voltage Sensing Considerations For Multiple
Arc Systems
Special care must be taken when more than one arc is
welding simultaneously on a single part. Multiple arc
applications do not necessarily dictate the use of remote
work voltage sense leads, but they are strongly
recommended.
If Sense Leads ARE NOT Used:
•
Avoid common current paths. Current from
adjacent arcs can induce voltage into each others
current paths that can be misinterpreted by the
power sources, and result in arc interference.
If Sense Leads ARE Used:
•
Position the sense leads out of the path of the weld
current. Especially any current paths common to
adjacent arcs. Current from adjacent arcs can
induce voltage into each others current paths that
can be misinterpreted by the power sources, and
result in arc interference.
•
For longitudinal applications, connect all work leads
at one end of the weldment, and all of the work
voltage sense leads at the opposite end of the
weldment.
Perform welding in the direction away from the work
leads and toward the sense leads.
•
For circumferential applications, connect all work
leads on one side of the weld joint, and all of the
work voltage sense leads on the opposite side, such
that they are out of the current path.
