34281Re: [Heathkit:Yahoo] Re: Soldering, aka Soldering Guns (and a good buy on one)
- Jul 5, 2014Hi Phil, et. al.
One of the more useful soldering aids I recently purchased was the
Weller "Portasol P2KC", a self-igniting soldering iron. It runs on
Butane and the set comes with multiple tips for a variety of jobs.
Despite its small size it can handle a PL- coax plug! It heats
relativey rapidly and a single charge of Butane gives you over an hour
to "soldering time".... That is a LOT!! It easily fits into a shirt
pocket, etc... great for antenna work outside!! It is NOT a "one size
fits all" solution, and I still have/use my Weller Soldering Guns, but
if you are working without access to electricity, you can't beat it! I
never leave home without it! <grin>
