Auto-darkening masks/helmets have transformed MIG/TIG/ARC welding in the last ten years or so, now becoming more affordable (typ. £50 budget; £200 top-of-the-range)
This is one of the best available, with a full set of controls for shade (9-13), sensitivity and delay, making it very suitable for MIG welding. Also has a large visor area and side-panes + easily changeable front screens and filter glass inside. It's a Hornell Speedglass 9000 series (Swedish) and obtained for £100 on eBay when less than a year old (originally £200+)
Some Hornell AD helmets have a fixed shade which can be increased using a different internal shade filter.
Some Hornell AD mask/helmets are sold under the BOC brand name.
Typically these types of welding mask/helmets offer fair light & vision prior to striking up, and darken down to the pre-set shade within a couple thousanths of a second... making lining up and preparation for striking up much easier than a fixed dark shade mask. I tend to use 10/11 shade setting, occasionally 9 at very low powers.
Even in normal light when not darkened they still offer full UV protection
They can also be obtained with integrated breathing equipment.
