What would really help welders would be actual augmented reality welding - like you have a monitor in your helmet which shows you the environment in normal daylight with high contrast and also shows you the puddle under the arc in normal daylight with high contrast - but doesn't show you the blinding bright arc itself (instead it shows a convenient indicater for where the arc hits the surface and whether you are too near or too far from the surface with the gun).
Basically welding as if you had eyes capable of filtering out the bright arc without any reduction of contrast or brightness anywhere else. For extra satisfaction add some microstabilization to the gun, so it can help you keep the tungsten needle at the optimal distance to the surface despite your hands becoming more jittery as you age.
