I ran out of easy solder and had some medium solder. Now I fear
If you’re going to use different solders on the same piece, start
with hard, then go to medium, then to easy. This is because a piece
with a joint that is soldered will be in danger of flowing at that
solder’s melting point, so if you are trying to heat it to where the
hard solder will melt and flow, and the piece has lower-melting
solder joints present, you’re going to have a mess on your hands. Go
the other way, starting out with hard, and you won’t have to raise
the piece’s temperature as high for subsequent work with easier
ii) Was my failure due to the piece being so much bigger than
pieces I had previously tried?
iii) Is the failure due to the butane torch not getting hot enough
quickly enough and thus the silver melting before the solder
Likely the former. You need the whole piece to be fairly hot, but not
too hot, and you need to be able to get good heat along the solder
joint. It might be that the torch you’re using isn’t giving you
adequate control over where the heat is going, and that could be
either the shape of the flame, or your inexperience in guiding it.
The second problem I have encountered involves previously soldered
joints melting and the piece collapsing when trying to do the next
See above – it could well be that you’re trying to get the piece
hot enough for hard solder after using easy solder nearby.
I have read your posts on this subject and am curious about the
whiteout pen. Is this simply the correction fluid used in the
office? And if so do I simply paint it on previous joints and
anywhere I do not wish the solder to flow?
Yes, it’s the office-supply stuff, and it blocks the solder flow
while you’re working, then washes off easily.
