REMOTE VOLTAGE SENSING LEAD
Above diagram shows electrode connected positive. To change polarity,
turn power off, reverse the electrode and work leads at the power source and position the switch on wire feeder (if equipped )
to proper polarity. Also refer to note N.F.
For proper setting of switches on power source, see power source operating manual.

connection must be changed whenever the | electrode polarity is |
changed. |
