ok the difference between a iron and a gun is the shape one looks like a glorified pencil and the other looks about the size of a 9mm and the amount of power most irons arn't more than 40Watts and a gun well the lowest i have seen a gun is 100Watts the gun i use is huge and very scary to solder to bits with because it's variable from 240/325Watts. most people will tell you that if you buy a soldering iron get the most powerfull you can find because they heat up fastest. most irons take about a minute or two to get to the temp it takes to melt the solder whereas in my case my gun takes about 5-10 seconds. the need to errrr ummm "refill" a soldering gun is that you need to buy solder which comes on rolls from places like radioshack.
