Just starting TIG welding and I need a good auto-darkening helmet for fine work. It has to fit my large head and a respirator mask and darken at very low TIG amperage.

Weight may not be a big issue as I don't plan on any long days of welding.

I keep coming back to the Lincoln Viking 3350 4C with its $50 rebate. it has good low amperage sensitivity, but the Miller X-mode sounds interesting too.

I haven't tried them on yet, but the Millers sound like maybe a smaller fit and might have enough comfort space for. The Lincoln seems like one of the larger ones.

I am open to looking at others.
