Before discussing the construction of the column and stillhead a word should be said about soldering. There are two solders in common usage — the low temperature lead-free solder which melts at around 350°C. and silver solder which melts at about 1300°C. It is possible to manage with just the low temperature solder, but there are situations where a small joint needs to be made close to an adjacent one, or close to a larger one which needs a large flame, and in such situations there is a danger of one joint melting while the other is being made. By using silver solder for the small pieces this can be avoided.
