I got them at Harbor Freight, but if youre gonna use wire-anything, Id definitely look for a variable-speed...it makes a world of difference, and the one I found was pretty inexpensive if I remember correctly. A wire-wheel spinning at 10,000+ rpms, well, you get the picture lol. And youll DEFINITELY need more than just goggles, Id suggest a full face-shield and welding gloves.
