*The electrode voltage 67 sense lead is integral to the control cable to the wire feeder.
Work Voltage Sensing
The standard POWER WAVE 355M/405M default to the work stud (work sense lead disabled)
For processes requiring work voltage sensing, connect 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 current path. Enable the work voltage sensing in the Power Wave as follows:
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 disconnect 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 configure the work voltage sense lead appropriately.
ELECTRODE VOLTAGE SENSING
Enabling or disabling electrode voltage sensing is auto- matically configured through software. The 67 elec- trode sense lead is internal to the cable to the wire feeder and always connected when a wire feeder is present.
PF10M feeder has user preference features to select voltage senses temporarily for testing sense leads.

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