can give a blue flame with a pale blue inner cone it is hot enough for
silver brazing. How big a piece it will braze depends on the size of the
flame. The hottest part of the flame (as you'll know but others may not) is
just beyond the blue cone.
The Go System torches are all labelled with the flame temperature they can
The lowest is 1300C (not F).
