Stopped by a shop in Gary and saw a brazing trick I'd never tried
I was passing through Gary last Tuesday and stopped at a small fab shop a buddy recommended. I figured I'd just say hi and grab a cup of coffee, but I ended up watching one of their older guys braze a copper joint with a special flux I'd never seen before. He said it's been his go-to for 20 years because it stops oxidation better than the standard stuff. I tried it this morning on a stubborn fitting at a job site in Hammond, and sure enough, it flowed cleaner and took half the time. I'm thinking about switching my whole kit over now. Has anyone else run into a flux that really changed their approach?
