Being pedantic 1/4's should 6.3mm and 6 guage should be 4.8mm (or was that US sizing) so to cater for everyone we used to make the lot
4.8, 5.0, 6.0, 6.3 and even 7.0, 8.0 and 10mm. The 10mm stainless were beasts, used for welding Centurion Tanks.
4.5mm and 5.6mm also cropped up occasionally
6mm are very rare these days. Replaced by MIG.
In an attempt to keep on topic. We used to produce an electrode sized by fillet size. So instead of 4mm or 5mm it was called "a4", "a5", "a6" etc which were the throat thicknesses produced if the weld length was 900mm (they were the 600mm long electrodes). That used to cause some confusion with the Inspectors on their WPSs. I had many a long conversation about that one.

yes, I did realise that the mm to the old SWG sizes I quoted were not exact, but a generalisation of sizes we used amongst the old schoolers, and they would be as near as we could get.
I also remember using a 5.6mm rod when I worked in West Germany in the early 80's. It was a beast to use, and it was for stoving down overs on ships frames. The sparks & fumes were horrendous.
Just been useing 4.5 rods Lincon Ferrod 165a 600 long Its a 7024 iron powder not seen them before
