What about the opposite?
Flux wire setting for gas/wire welding. I noticed crappy welds that way.......
Since I am not a physicist, I can only assume it is due to the break down of the charge when DC welding, which is 1/3 negative and 2/3 positive along with the directional flow of electrons, which is negative-to-positive, and when negatively charged, the flow must not be high enough from the MIG wire to fuse the material. Would also have to assume that shielding gas must also have something to do with it, as there is a Flux core gas welding, known as outershield flux core wire, and with that, you run the same polarity as MIG.
