I am using a small mig with 0.8mm wire, with a CO2 Argon mix. Just playing around with the settings to try and get a half decent weld. I am far from an expert.
I saw that build with the note on the dash. I don't think mine is quite to the same level as that. I also don't want to be blamed for half of the other bodgy conversion stuff that has been done. It could be worth leaving a note about the videos so at least the next owner can see the bits I did
