Sorry for not mentioning it, it's an AC/DC TIG welder.
Needs a (?two?)) potentiometer(s) in it as well as a switch, to control
They don't seem to actually supply footpedals for this model, so I am a
little wary about buying it - I really prefer using a footpedal when TIG
There is a circuit diagram at
but it's for a different model, and it doesn't work on the similar but
very much cheaper DC "digi" machine I already have.

Surely the existing electrode holder will have a button the control the
strike etc. It will not have potentiometers. If its connection via the 7
pin socket is replaced with a foot switch the you will have what you need!

I want continuous foot control of the welding current - an on/off switch
is not enough here, you need a potentiometer for that (or two, the
second to adjust maximum current).
(you also need an on/off switch, as well)
Continuous control of current makes welding a lot easier, also you can
do things like pump the footpedal to get a pulse effect, whose timing is
controlled by you. There are other advantages too.
Maybe it's just the way I was taught, but I really like continuous
