Russ, Try to shake the 1 gallon jug and see if you can create foam on top of the liquid. If you don’t see any foam at all something is wrong with the flux. Patrick

If I shake it hard, I get a thin foam which quickly goes away. Not sure what it should look like.

As long as you see foam it's probably not the flux. Try to increase the flux level in your fluxpot that should help reducing the bubble size.

Shenmao SM-816 is alcohol based no-clean liquid flux and can be used in the foam fluxer. http://db.tt/sHkmOOyf If you'd like more info, contact me offline.

OK, still haven't figured this out. New flux, new air pump, new tubing, new stone, but flux still not rising enough. Pump has correct voltage. We've eliminated everything, but we still cannot find the problem. What else could possible keep the fl

We don't have the equipment to check specific gravity, we just assume what's on the bottle is correct and we've never had a problem. The stone sits in an open chamber, so there really isn't any pressure to check. When we vary the air flow, the foam

We've got a Novastar 12S wave solder machine and we've been using Kester 951 flux for years with no problems. We just got a new bottle of 951 and it does not foam correctly (thin foam with lots of large bubbles). After a lot of back and forth with

Check specific gravity: According to a quick web search, the specific gravity should be 0.813 ± 0.003. If you have records of the specific gravity, compare current reading to past readings. Check pressure near stone: if you have records, compare

Oswaldo, Your reasoning is correct, but the strange part is that Russ didn’t have a problem for years using the same flux so you would assume his fluxer is designed for low solid fluxes.
