Flux is your friend. When it turns glassy w/ no bubbles then it's hot enough to melt the filler metal - too much heat and you roach your flux. Use a flux that wets out at the right temp for your filler. For bronze or nickel silver I use Gasflux type "B" - similar to Harris #17 (that blue paste stuff).
