1 point to Frank. MAPP Gas works well.

I'll take the point, however, I was a fitter/welder in my early life
and also did instrumentation tubing and piping building offshore deck
sections and platforms. I don't think I ever ran into a joint I
couldn't solder with propane because of cold or windy weather.

I have. Pipes with persistent water drips/leakage. My std trick was to
shove some bread up the pipe to act as a dam; it'd blow thru/dissolve
as soon as water pressure was back on. Alternatively I'd use
oxy-acetylene and just boil the water away.

Water is a different story. sucks heat away too fast. I've done that
(bread dam). Works like a charm. But dry cold never got me on copper
tubing

Never
did wiring that way.

Ditto.


Most days, however, you could not use GMAW (Mig) welding because the
inert shield gas blew away to quickly causing porosity.

Yep. For outside work I use either a stick welder and E4111 (6011 in
USA land) rods or flux cored wire on the MIG. Just been doing that
using a spoolgun (http://www.readywelder.com) for fixing steel
reinforcing.

6010 and 6011 mostly used for tacking and stringer pass in pipe or
structurals in my experience. Mostly finished up with LH7018. Most
of our codes required the higher tensile and the low hydrogen rods.

I welded pipe out of postition mostly in 5g and infrequently in 6g
modes. I also did a lot of lifting lugs for offshore deck sections,
primarily vertical up. None of my jobs ever failed on a derrick barge
lift, thank God, but I always worried.

Most of our customers, (U. S. Oil Companies) at that time ('70s) did
not trust FCAW and wrote it and GMAW out of the specs. Probably has
changed now, I haven't kept up. But I certainly enjoyed that work. It
was very satisfying.

This is the simplest way. Although I liked some of the
other answers too.

You are trying to solder a connector in cool high winds.
Because of the wind, the part cools faster than your
propane torch can keep it hot.

If you can't get out of the wind and can't wait to complete
the job, what is the simplest work around to get your part
soldered? [1 pt]


Switch out the cylinder to MAPP or some other higher BTU alternative.
