Not that long ago, you could find those big soldering irons at garage sales, swap meets, just about everywhere - but I guess the supply has about dried up since "nobody uses that type of thing anymore." I had a  pretty big one that I used from time to time, but the element finally gave up the ghost.

 

You can also use a propane/map torch if you don't have access to an iron. Or even silver solder if you want a stronger bond. BUT for fuel tanks, you have to get all the gas vapor out first.  Pretty easy for small gt size tanks - get all the gas out and fill/drain with water a few times to get all the fumes out of the tank. But a non-flame option is probably safer!!!

I am not a tinbender but I see the guys at the sheetmetal shop using the old irons that you heat up using a flame. Once the big iron is hot, it is used just like a regular electric iron. I did see an old guy us a propane torch and an old tire iron one time the same way. It was for soldering up a gas tank too.

I soldered a gas tank recently, excellent results too. Still leaks... But it is a slow leak around the fitting thread insert... Bummer, should have soldered it too lol.

There is a company that makes the big irons, American Beauty Tools. They are expensive, they sell mostly to people doing steel and copper roofing and gutter work.

Any idea how many watts would be required in an iron to do these kind of repairs?
