FAQ:

Q: What is the purpose of rosin core solder?

A: – Alloy Materials – the proportion of elements used to make the solder (determines solder’s melting point) – Core Type- determines whether the solder is flux-filled or not ( acid core and rosin core and self-fluxing solders, unlike solid core) – Application– special solders, such as aircraft solder, automotive solder, or general solder

Q: How to make your own solder flux?

A: R (Rosin) – pure rosin,no activators,low activity,mildest WW (Water-White) – purest rosin grade,no activators,low activity,sometimes synonymous with R RMA (Rosin Mildly Activated) – contains mild activators,typically no halides RA (Rosin Activated) – rosin with strong activators,high activity,contains halides

Q: How to solder automotive wiring with rosin core?

A: Be sure to remove all of the damaged wire section. Use the Micro Torch with the Hot Knife attachment to strip and prepare the wire ends for soldering. Make sure you have a clean solid mechanical connection before soldering. Use Rosin Core Solder when soldering wires,the flux deoxidizes and allows solder to penetrate into the wire strands.

Q: What is solder flux and how to use it?

A: Cleaning the dirt and oxidized layer on the metallic surface to be soldered. Reducing the surface tension and viscosity of molten solder to improve the wettability. When contact and spread on metal surfaces prevent metal from being re-oxidized at higher temperatures. Allow molten solder paste to form solid long-lasting electrical and mechanical joints
