I've many years experience with Mig-Co2 but never used gassless before. I was put onto the Forney brand by a youtube reviewer and thought I'd give it a chance. It was every bit as good as he said, easy to use and leaves only a dusty slag residue which just brushes off. Gasless is really only for outside use IMO as there is a lot of smoke. Alternatively, use an airfed mask if you have to be indoors. I used the wire to build a new section of chassis for my truck and will buy more.

Best wire I have found on Amazon. Low splatter, good welds. I’ve tried others and they don’t compare.
