Yeah, I see the smilie, but I'll answer anyway. With a regular iron or
soldering gun, you can get a bead of solder on the tip. Just get the joint
hot, and the bead flows right into it. The tip on these things doesn't get
hot enough for that.

Plus the fact that the dot of solder on the tip will deform around the
object you are working on to aid in rapid and efficient heat transfer.

It also seems like the cold solder gun depends on having the object you are
soldering having about the correct resistance to make the appropriate amount
of heat.

Thanks for the review, all. I thought there would be major problems, and it
looks like I was right. I'll stick with my soldering gun/iron/butane torch.
