Hello! Wondering if anyone can shed some light on an issue i’m having while soldering.
I use a Boric Acid Powder/denatured alcohol mix prior to soldering, with a paint brush applicator. The solution clumps just as it hits the metal.
I use a butane torch to heat it, it bubble and becomes dark and sticky, dirtying the joint. Then my solder doesn’t flow properly.
I work in a garage for now, in Toronto so the weather is colder. Is environment temperature an issue? Is it the Borax mixture?
Any help would be great. Thank you.
