[TheForge] Soldering copper tubing in an AC unit

[Bruce .]

I don't know whether HVAC might be different, but for copper water
pipe, a simple propane torch is recommended.  (I HAVE  used hotter
torches for such work, but only when I needed to keep a nagging water
drip away from the area to be soldered.)

The copper should never get red, as the solder doesn't need such a
temperature to melt and flow.  Soldering, as opposed to brazing, can
be done with a copper-tipped soldering iron (which IS heated to barely
red).  Hotter than that is brazing.  The distinction is a bit
arbitrary, but important.  Torches are more convenient.
