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 or hot 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 above right corner. 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, above right corner. 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.

Solid Wire Solder means NO core chemicals (Rosin, Acids and others) which could interfere with our Fluxes

when soldering.
