We've been asked about using propane or MAP gas when sweating or soldering copper pipe. In fact, both types of fuel can do the job. The main difference between propane or MAP gas is that MAP is hotter. This means you'll heat up the pipe faster and thus weld faster.
The case for MAP gas over propane
If you can heat the fittings quickly, you'll actually be heating less pipe area. This can make things better when working near valves.
Also, tin- and silver-based solders require more heat to make them flow because lead-based solders do not meet specifications for domestic water systems. MAP can also do the job faster.
Caution is required as most flare tips designed for propane are not compatible with MAP gas unless specifically indicated on the flare tip. Before trying to switch from one tool to another, make sure you understand which tool to use.
MAP Gas Definitions
The name MAP is derived from the original chemical constituent, methylacetylene-propadiene. You basically have a stable mixture of methylacetylene (propyne) and propadiene.
MAPP Gases is a trade name, owned by the Linde Group, spun out of The Dow Chemical Company.
