Auto-darkening masks/helmets have transformed electric MIG/TIG/ARC welding in the last ten years or so, now becoming more affordable (typ. £50 budget; £200 top-of-the-range)
This Hornell Speedglas illustrated below 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 £220) in 2006
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. 10/11 shade setting is normal for general MIG bodywork welding, 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.
NB. Gas welding goggles are only about shade 3 and entrirely unsuitable for electric arc/MIG/TIG welding
