I picked up a miscellaneous box of TIG bits, including these three Weldcraft gas lenses:
They're larger than I need for my little 180 amp Miller (the mesh 'lens' portion is about an inch in diameter) so I'm passing them on to someone that can use 'em. Two are new, one's been used. Two are 1/8" (max electrode diameter) and one's 3/32".
Call it $20 each, and if you buy all three, I'll ship 'em free. (Inside the US, that is.)
