@Lubelltx

If you are using RG 45 mild steel welding rod with a copper sheath (coating) - the black will not come off. The black is where the thin copper sheath of copper has burnt off.

Boiling water should remove the flux.

@Lubelltx The black color: If you notice on many of the pieces that I do where I use the copper sheathed welding rod, I work the black color in with the design. Notice some of the pieces in the "Small Sculptures That Sell" YouTube video as well as in other YouTube videos. The black against the copper that hasn't burnt off and the bronze brazing provides an interesting contrast.

I use 3/32 (diameter) brazing rod for most everything I do. That would be brazing 1/16 to 3/16 thickness.

If you are brazing thicker material you can go with 1/8 or even 3/16 diameter brazing rod.

I found your video very helpful but i'm doing metal working at my school and we do brazing and fusion welding and i'm just genrally bad, i've only been welding for about a month now however I just find that my welds look very poor and as i'm welding togeather a wine rack I would like to improve my general skills if you have any other advice. Thanks.

@Jaffa4567 Sounds like to me that you are putting too much pressure on yourself. Just relax. When you are welding and brazing try not to think about the process and just let your mind take over. You’ll see a short section that comes out perfectly. When that happens just try and repeat which you did to get that perfect section of weld.

The rod will splatter when it's too hot.

@Lubelltx think your flame is kinda to hot for that

HELP RHONDA Please----I am working with 1/8" copper coated steel rods. When I braze with a flux rod it does great, EXCEPT the rods turn black on each side. I have tried liquid dish detergent and I'm using a powered flux. The flux is grandulated and will not come off. I've tried to hot water for 10 minutes and it's not working----HELP
