## Questions & Answers

**Q: What is the difference between the different SRA numbers? For example this one says SRA# 312 and another is SRA #99-20 and there are even more.**
A: Flux normally comes in three different strengths, light (no-clean), normal (RMA), and strong (Water Soluble). #312 appears to be the weakest one and probably best for light work on sensitive materials. #90-20 appears to be the medium strength and probably the best for general all around use. #80 "This is a high activity halide, Neutral organic acid (OA) flux formulated for difficult-to-solder surfaces where activated rosin fluxes and less active OA fluxes cannot be used." (and probably not needed except for extreme situations).References: http://sra-solder.com/sra-312-no-clean-flux-pen-refillable/http://sra-solder.com/sra-99-20-rma-rosin-flux-pen-refillable/http://sra-solder.com/sra-80-water-soluble-flux-pen-refillable/

**Q: What do you use to refill with, how, what brand, etc...?  I want to try but want to know before I order and need more of something that I do not have.**
A: This is the same pen with a bottle holding 5 refills included http://www.amazon.com/SRA-312-No-Clean-Flux-Refill/dp/B008Q1F92E

**Q: Can this flux be used to solder 2 pieces of magnet wire together? If not, what flux do I have to use? Thank you a lot!**
A: I'm honestly not to sure what you mean by two magnet wire? I'm imagining you mean joining  two solid (magnetic) rods together? In this case I would imagine a 50/50 lead/tin solder however, I'm not sure what the magnetic rods consist of. You may want to consider a mig/tac.

**Q: I make jewelry and I need to solder some pieces together. Will this work for it?**
A: This is flux so you would need solder.  This is mainly used for electronics
