While fillet welding 18 gauge to 1/8' steel , I am getting a yellow flashing , that is too bright to see the weld . Material is 18 cold rolled to 1/8 hot rolled . Hot rolled was sanded and wiped with non chlorinated brake cleaner . The welder is a 300 Dynasty DX with knobs . Gas flow at 17.5 CFM . I have seen this occasionally before , but this piece seems to be unweldable .

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...

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
