c.Locate the 8-position DIP switch on the control board and look for switch 8 of the DIP switch.

d.Using a pencil or other small object, slide the switch to the OFF position if the work sense lead is NOT connected. Conversely, slide the switch to the ON position if the work sense lead is pre- sent.

e. Replace the cover and screws. The PC board will read the switch at power up, and configure the work voltage sense lead appropriately.

Voltage Sensing for "Slave" machines

If "Slave" machines are configured to use remote volt- age sensing they receive these signals directly from the "Master" machine. The K1795 control cable used for parallel connection of machines contains both the ELECTRODE sense lead (67) and the WORK sense lead (21). No other external sense lead connections are required for "Slave" machines.

NOTE: All of the machines of a given arc group (both Master and Slaves) must have their work voltage sensing configured identical- ly. All must either use a remote lead or sense directly from the stud. For addition- al information see the "Work Voltage Sensing" section of this document.

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 strong- ly recommended.

If Sense Leads ARE NOT Used:

Avoid common current paths. Current from adja- cent arcs can induce voltage into each others cur- rent 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 com- mon 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.
