I had a little mishap with the suction stub-out on a 1/3hp condensing pkg. My boss says there is no hope for repair and that I should scrap it out, but since I broke it I want to try to fix it. The problem I'm having is with brazing the dissimilar metals. From what I have read on the Sil-Fos site anywhere from a 40% to 56% with flux is reccomended. Does anyone here have experience with brazing steel to copper and what product is best to use. Thanks in advance.
