The good news is that testing a misfire code, or misfire codes, or a rough idle condition is not that hard and it's something you can do! In this tutorial, I'm going to explain in some detail the most common causes of misfires and misfire codes (P0300, P0301, P0302, P0303, P0304 -OBD II equipped 1.8L Toyota).
Solder flux is a type of metallurgy component used when soldering two metals together. The flux is an inert substance that prevents the formation of metal oxides at extreme temperatures.
+1 for best description of the actual purpose. 5 years agoReply. acidic fluxes partially strip existing oxides from the surface of a metal, (these are used almost exclusively for plumbing and related welding/brazing/soldering processes. For electronics and most electrical soldering, non-acidic rosin flux is used. AFAIK, the primary purpose of flux (in general) is to prevent oxidation during the soldering/brazing/welding process. The MadScientist 5 years agoReply It basically makes the solder stick.
