91% Tin 9% Zinc Solder for Aluminum

Questions & Answers

Question: Do I need to wash No 30 flux off Model RR Rail after soldering joints and wire to rail, or other general soldering?

Answer: NO - not if you do not use an excess amount of flux on the joint and the joint is heated properly. Circuit boards must be washed with warm water.

Question: I am forever spilling my flux, what is the best solution. (Bad for you, nice for us, we sell a lot of flux because of this). I even get panic phone calls: I spilled my flux and I can’t solder, ship me some, ASAP, no matter the cost!

Answer: See picture. On my work bench, I keep my bottle of flux in a piece of foam with a hole for the bottle.

Question: How is the best way to apply the flux to what I want to soldering.

Answer: See picture. With small artist type brushes. I just keep them stuck in the foam and choose the best size for the job. When done for the day just rinse them in water.
