I've been told that in Australia the big name
in welding equip. is CIG. Their tip sizes, 6
through 32 correspond to 0.6 to 3.2mm
orifices.
Far too logical.

They are not exactly the same sizes as the US tips they are aligned with, but close enough for comparison. He also provided the Welding Thickness/Tip Size chart. Aaron Novak supplied the #6, #7 and 1/2 size Meco Midget tip sizes. Several others sent me the Linde, ESAB, Prest-O-Lite & Purox-W-200 Sizes.
