I've just acquired a Lincoln minimig 180, but a little confused with thread size. I've only ever used disposable bottles in the past, but I do have a couple of aquarium co2 regs which I hope will work.
Reg 1
Single gauge with solenoid.
It fits the Co2 bottle, but the needle valve is designed for 4mm aquarium airline.
I can unscrew the needle valve but unsure what thread it is.
I was thinking of getting something like this.

Reg 2
Same fittings as reg 1 but 2 gauge, no solenoid
