    Solar

    Maybe it's a Solar Welding Shield ?

    Have you checked the Hobart site for your helmet??

    is it one of these?? have been unable to cross it by the "770098" number

    They all seem to use just one battery that is behind a threaded door..
    like a miniature manhole cover..

    There are more manuals here

    I have done my Miller BWE a few times..

    the battery tray is not readily apparent the Hobart may be similar..

    flaky batteries can drive you crazy..

    Am betting it takes a pair of Panasonic CR2450 button cells..

    CFM vs CFH

    Am Curious...

    what brand and model helmet...?? might need new batteries..

    BTW... Argon flow would be in CFH (Cubic Feet per Hour)... 17.5 CFM would be a hurricane at the torch... and you would be trading gas bottles a couple times an hour..

    solved

    The problem was the automatic helmet sensor not seeing arc and the bright yellow is the normal welding color . Repositioning the assembly solved mystery .
