Used twice, thought I'd use it more. Does stick and Tig. Plugs into either a 120V or 220V curcuit, automatically switched internally to adjust. Very small and portable. Purchased one year ago, and still has 2 years left on the warrantee. Seen it new for $1500 plus taxes ($1717.50). Will include large boxes of 7018 and 6010 rods.
