On the first pull of the MIG torch trigger, the helmet will flash me. On the second pull it'll auto darken like it's supposed to. On the third pull, it'll auto darken again just fine. Let the helmet sit for a minute, it'll flash me again on the first pull. Sometimes I can "activate" it by holding it up to a light source before pulling the trigger and it'll auto darken on the first pull. It seems as though the helmet is timing itself out after sitting for a length of time. The battery charge icon shows a full charge. The batteries are the factory original batteries. This is the ESAB Sentinel A-60.
