Why can't we make a soldering iron that works like a hot-glue gun?

I don't see why this whole process of soldering can't be simpified by using a hot-glue gun-style iron. It seems a simple matter: squeeze a small amount solder through a hollow, heated tip.

This has to have been tried before, so I'm expecting someone knows why we can't have one-handed soldering.

I'm pretty sure the reason is.... that's not how soldering works. The surface to be mated needs to be heated in order to accept the solder. Also most solder has a flux core to clean the surface for better bond. Pre-melting removes that 'necessary feature' :P

Doh! I forgot what else you really had to do when soldering. They do make attachments that feed solder, though. Supposedly they're too fiddly and inconvenient. Maybe I'll just grow another arm. :P

I guess it's because soldering isn't like gluing two parts together. You need to master the skill, to avoid cold solder joints. All about controlling the heat. Be it body solder, plumbing solder, or electrical/electronic components.

So it's just an easier thing if you have one, simple, versatile heat source that you can apply in a number of ways? That makes sense. Plus the whole cold joint thing. Grrr...Why don't we just use light-computers, already! :P

Be it body solder, plumbing solder, or electrical/electronic components. After becoming hemiplegic, I went looking for a way to make soldering with one good hand easier. While there are attachments to feed the solder to the tip, I found them lacking. Hard to control both the application of the heat, and the application of the solder at the same time. Sorry if this turns out to be a duplicate post, something hiccuped.

(about 1/4 of the way down the page)

most problems will have to do with viscosity, amount of heat needed and the fact that soldering irons are used to take things apart, not just put them together : )
Because the tipsolder would melt inside of the tip, and then bond to the entire tip, it won't just flow out evenly. The other problem is, that a stick of glue lasts for a long time, that much solder wouldn't last long, you would have to get a motor to use as an electric feeder.
