Am I being stupid? Wire feed roller labels.

    Okay so I have 0.8mm wire... I put it in the machine and turn the wire feed roller to 0.8mm..
    However the labelling doesnt match up or make sense to me... It works if you just use the thinner groove for 0.8mm but can anyone explain the reasoning behind this labelling? Pictures explain it better..
    The fatter groove is labelled as 0.8 and the thinner groove as 1.0mm..
    However the wire feeder uses the groove closest to you, not the one furthest away... so even if the labelling was to mean "insert this way round for 0.8mm" it still doesnt work..

    Got it all working now but I'm just curious as to if I am missing something or if it's a manufacturer slip up?

    I think the idea is that the number you see (whilst roller is in position) is the one currently being used.

    What I think I'd advise is, the drive roller is clearly marked for use on either 0.8/1.0 wire; therefore the narrower groove must be for 0.8 as your using, provided that this groove aligns with both the guide tubes, the one from the spool, and the guide into the torch, once you've established this, I'd not concern myself any more

    Yeah I have checked all that and it's working as it should. But i wanted to check that i hadnt missed something that may have been relevant in future with a different set up.

    I have always had an issue where I want to understand everything I'm doing.. never been one to just be happy it works I need to know how and why :(.

    That's what I thought as well, but the number shown is 1mm and I'm using 0.8mm wire and the narrower groove.. anyone have a machine that uses the inside groove when its mounted? In other words instead of everything being aligned for the outside groove, everything is aligned on the inside one?

    Goes off to check welder.
    You Sir, are correct. Rather illogical but not easy to see the markings anyway so.

    Can't understand even if a roller has 0.8 and 1.0 marked the same side it's pretty obvious from the size of groove which one is which. ( Good photos by the way).

    My oxford uses the inside grove when its fitted, opposite to yours.

    I've got rollers that the number written on the side is the grove furthest away, and i have some knurled rollers that are the opposite. Best way is just to look and work out which one you need.

    It's probably a bought-in item designed for use on a different model of feeder, so even if its labelled wrong, it works fine if you look carefully :)
