WORK VOLTAGE SENSING
The Power Wave is shipped from the factory with the work sense lead enabled.
For processes requiring work voltage sensing, connect the (21) work voltage sense lead from the Power Wave to the work. Attach the sense lead to the work as close to the weld as practical. To enable the work voltage sensing in the Power Wave, refer to the section DIP
SWITCH SETTINGS AND LOCATIONS.
ELECTRODE VOLTAGE SENSING
Enabling or disabling electrode voltage sensing is auto- matically configured through software. Electrode sense lead 67 must be connected at the wire feeder.
CONTROL CABLE SPECIFICATIONS
It is recommended that genuine Lincoln control cables be used at all times. Lincoln cables are specifically designed for the communication and power needs of the Power Wave / Power Feed system.
CAUTION
The use of
Lincoln control cables are copper 22 conductor cable in a

POWER WAVE / POWER FEED WIRE FEEDER INTERCONNECTIONS
Connect the control cable between the power source and wire feeder. The wire feeder connection on the robotic Power Wave is located under the spring loaded output cover, near the bottom of the case front. The control cable is keyed and polarized to prevent improp- er connection.
For convenience sake, the electrode and control cables can be routed behind the left or right strain reliefs (under the spring loaded output cover), and along the channels formed into the base of the Power Wave, out the back of the channels, and then to the wire feeder.
Output connections on some Power Waves are made via
A work lead must be run from the negative
CAUTION
Excessive voltage drops at the work piece connection often result in unsatisfactory pulse welding perfor- mance.
EXTERNAL I/O CONNECTOR
The Power Wave is equipped with a port for making sim- ple input signal connections. The port is divided into three groups: Trigger group, Cold Inch Group and Shutdown Group. Because the Power Wave is a “slave” on the DeviceNet network, the Trigger and Cold Inch Groups are disabled when the DeviceNet/Gateway is active.
The Shutdown Group is always enabled. Shutdown 2 is used for signaling low flow in the water cooler. Unused shutdowns must be jumpered. Machines from the fac- tory come with the shutdowns already jumpered. (See Figure A.4)
