    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 .

    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 .

      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..

        Helmet

        Helmet is a Hobart 770098 . I am guessing 12 years old . Never had a new battery .

          flaky batteries can drive you crazy..

            helmet battery

            Does anyone have experience replacing the battery or batteries in the Hobart 770098 helmet . It appears to be a sealed unit .

              I have done my Miller BWE a few times..

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

                  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

                    Maybe it's a Solar Welding Shield ?
