Here is an explaination from Jetline
http://www.jetline.com/HWP-50D%20Brochure.pdf
In "Hot Wire" GTAW current is run through the filler, the resistance heats it and the result is increased deposition... I think it us usually a semi-auto or mechanized GTA process.
"Cold Wire" is plain ol hand feed of bare rod.
