Torch Pot Output
Some power supplies can utilize a variable DC voltage signal from the gun
potentiometer adjustment as their external voltage control. Adjusting the
potentiometer at the gun will give 0 to 10VDC output between TB1 – 1 (GND)
and TB1 – 6 (POT).

A common “synergic” type of setup is to have the gun potentiometer signal
control the welding voltage of the welding power supply. As this external
signal adjusts the voltage up or down, its external 0-10VDC signal can come
back into TB-1, as shown below in External Motor Speed Control, and control
the wire feed speed.

This is mainly dependant on the configuration and signal adaptation of the
welding power supply. Check with your welding equipment manufacturer to
see if your welding power source has this feature or can adapt to this type of
setup. Not all welding power sources can do this.
