*The electrode voltage 67 sense lead is integral to the control cable to the wire feeder.
Work Voltage Sensing
The standard POWER WAVE 405’s default to the work stud (work sense lead disabled)
For processes requiring work voltage sensing, con- nect the (21) work voltage sense lead (K940) from the Power Wave work sense lead receptacle to the work piece. Attach the sense lead to the work piece as close to the weld as practical, but not in the return cur- rent path of the electrode to the ground clamp. Enable the work voltage sensing in the Power Wave as fol- lows:
WARNING
• Do not touch electrically live parts or electrodes with your skin or wet clothing.
•Insulate yourself from the work and ground.
•Always wear dry insulating gloves.
1.Turn off power to the power source at the discon- nect switch.
2.Remove the wrap around cover from the power source.
3.The control board is on the center assembly facing the case front. Locate the
4.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 present.

5.Replace the wrap around and screws. The PC board will “read” the switch at power up, and config- ure the work voltage sense lead appropriately.
ELECTRODE VOLTAGE SENSING
Enabling or disabling electrode voltage sensing is automatically configured through software. The 67 electrode sense lead is internal to the cable to the wire feeder and always connected when a wire feeder is present.

Important: The electrode polarity must be config- ured at the feed head for all
