In another thread ("Bernzomatic JTH7 High Temperature Torch") I posed the folliowing (paraphrased) question:
Is there anything wrong with a joint heating up very quickly with a very hot burner? Does the flux need time to do its work? Since the flame is so hot, perhaps only one side of the joint is getting properly soldered?
I know that copper is a terrific conductor of heat. Yet with a pencil burner I've often seen flux being pulled into one side of a joint and not the other even though I try to heat as much of the joint as possible.
Any comments?
