I have just bought a voltmeter to add to my Portamig 186s. Has anyone fitted one to this, or a Tecarc, which is basically the same machine. There are instructions but they are a bit crude and I am not entirely sure how the shunt resistor is wired up and what I connect the red wire to (positive output?).
