Fixing a gas soldering iron leak.
S. Heslop:
I bought a weller pyropen off ebay last week that was listed as not working and figured for the price I might as well take a look at it. From the description I was imagining the tip catalyst had just run out but it turns out the thing is actually squirting out a stream of liquid butane from the jet. I'm glad I noticed that before I tried lighting it!
I've had it in bits and not noticed anything obviously wrong with it (not that I'd know what to look for). I've tried googling about but I guess I don't know what phrases are used to try find information on this sort of problem.
Any help would be appreciated.

The wick should have helped the liquid to turn to gas, unless it was over filled.
Also only use Lighter refills only other sources of gas sometimes contains heavy hydrocarbons that do not vaporizer easy.
Camping gas tanks are big culprits.

I'm using a butane refill from maplins. I'd never expect their stuff to be good quality though. I wonder if covering part of the wick up near the brass end would help. I could maybe put some shrink wrap tubing around it. Although I'm not sure how well that stuff would survive in liquid butane. Or maybe I could interference fit a bit of brass tube in.

I have the exact same model, but can't look at it at the moment as I'm away for a few days.
I seem to remember a sintered plug that the gas defuses through :scratch:

Yeah I can see something sort of like that. It's all so tiny it's hard to get a good look. It looks like the iron had been dropped on it's tip at some point, judging by the upsetting on it, so maybe that dislodged something. But I couldn't see anyhting blatantly wrong. Might try digging out my magnifying glass.
