Weather or not You could interchange them depends on what ohm range the machine controlls are set up for. Short answer is probably not, but if You changed the background amperage pot to whatever the Lincoln machine needs You may be able to make it work. The other issue is system operating voltage. If both are 115V no problem, but a Miller 14 pin plug has 115V & 24V where a Lincoln 14 pin has 115V & 42V. You will have to study the schematics for all the equipment involved and figure it out for Yourself.
