Hi, I was using different brand machine but it will behave the same way as yours when it is dirty or clogged. Try to clean your nozzle and your supply mechanism(pump, propeller...) and you should get a smoother wave. Good luck!

azhiker, for me I selected method A. But I don't turn off wave and apply acid directly to nozzle with solder.

Bill, ENIAC, Thank you for your input. I'll do some research on the items you suggested and give it a try. The idea of having a steal nozzle that is thinned is defintely new to me, so I will check into that, as well as the brushes. Thank you guys.

You do not need much. We just take out pencil style stainless brush dip it in the powder and then scrub the nozzle.

Stephen, We are now running with 99.999 N, New nozzles and our wave height has stabilized. I will look into the Apidic Acid to clean our nozzles. Thanks for the input. I am just amazed at the difference the nitrogen grade made to our process. Goin

OK guys, we got our Adipic acid. What is the preferred methode of applying it? a) Nozzle mounted, momentarily turn off wave and then brush? Or b)coat nozzle with the acid then mount it and turn wave on? By the way, we are using Indium flux WF-994

We have a Versaflow 40/50 and ours is setup like this. We have out nozzle test position set so that in the Z axis you are 3.8mm away from the pin. Used feeler gauge Then you can set your gradient per nozzle. Start with a number then do a wave offs

We have an Ersa selective soldering machine here. We use the wire solder with the automatic feed. We dross and clean the pot roughly once a week. You can tell when it needs it by looking at the solder fountain. We do the nozzle at the same time. We c

Evtimov, thanks for your reply. Yesterday was our first day of running 99.999%. We were running for weeks with 99.99% Nitrogen purity and we just were having all kinds of problems with the miniwave not being consistent. We had a wave offsets at 75,
