I’ve got one of the EZ torches. I bought it more-or-less on a lark,
but it works pretty well. I have several other torches I like
better, so I don’t use it all that much, but it’s pretty good for a
’simple, one tank torch’. I’ve recommended it to students on a budget
with no reservations.
Harold O’Connor swears by his, which is why I bought one when he
came through for a workshop.
The big tip is pretty reasonable for annealing and soldering parts
up to about a 2x3" piece of copper. Would probably anneal up into the
small vessel range.
The little one is decent for medium small sorts of soldering. It’s a
pretty bushy flame, not nearly as focused as a presto-light, or
mini- torch, so you’ll hit a larger area with the heat, but it’s not
nearly as hot as either of those, so it works out about even.
I wouldn’t try to use it for retipping or anything where pinpoint
precision is required. I’ve seen Harold solder pinbacks with his, so
it is possible with practice.
The only drawback to the one I have is the little collar that screws
in and out to adjust the amount of air is very loose. If you set the
flame with the torch level, it’s likely to slide forward slightly as
you tip down to solder, changing your mix, if you don’t keep a
finger on it to keep it in place. That may just be mine, and not a
function of all of them. It’s fixable with a little work, if it
bugged me enough.
