GAS SOLDERING IRON/TORCH

I would be very grateful to somebody to know how to refill this iron. I did not find any butane lighter gas suitable to refill the iron: gas exits out of the iron. Is that necessary some intermediate part to apply to the mouth?

The thing that makes this gas iron better then most other gas irons is because when you light this iron, you are actually lighting the torch flame first. After letting that flame burn for a few seconds you then release the spring-loaded burner section, which extinguishes the flame and then provides fuel to the burner. Most other soldering irons only have a burner, which after many uses will no longer ignite or ignites intermittently.

The only cons are that it doesn’t have an igniter, so keep a lighter near buy. Also, the flame on the torch blows out easily.

I've used a lot of butane irons (weller, lenk, radio shack) and for the price this one's at the top. It's got a big tank, solid adjustment lever, built in stand and one exhaust port (easier to avoid melting your project). The tip converts to blower or torch by removing parts rather than using different tips, so you don't have little parts to keep track of. Replacement tips are cheap, so I got a couple extra, but I haven't needed them yet. It has a 3/4" cross section and suprisingly good balance which makes it really easy to handle and the tapered tip even works with SMC jobs. The only things it's missing are a cap(you have to let it cool before tossing it back into your field kit), and an ignition system, but who needs that anyway? Great value, even if it's just a backup iron.
