welding technique on american chopper?

I've seen a couple of diy shows on TV, and when they're welding, they use what looks like a mig welder, but also are holding a stick of metal that I guess they feed into the arc at the same time. What are they doing, and is this possible with flux cored mig machine, and is it for thin metal to prevent burn through? Thanks to all.

They are TIG welding (Heliarc). The thing that looks like the MIG nozzle is a torch that has a Tungston element in it. It makes a high frequency weld and the filler metal is hand fed. Makes a really nice looking weld and strong at the same time. Great for small areas and thin metal.
