Nah, with good filters, the UV radiation doesn't reach your retina. And modern masks have filtered ventilation too (in addition to workplace fume extraction if working indoors). But you need to focus on the workpiece, the gun, the puddle... the whole time. The contrast you get through that filters is shit - can't really see a lot apart from the arc and the puddle (especially if you are older). Being a welder guarantees a lot of eye strain. It isn't like they actually get damaged, but it can be very unpleasant nonetheless. And all that just because of that ultra-bright arc. With augmented reality, you could just see all the things like if there where no filter and the arc wouldn't be there.

The link mentions that the topic is mined with a patent. Sadly makes a lot of sense for no one even daring to think about innovating in that field then.

This is so extremely underwhelming that just a "meh" really doesn't cut it.

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.

Yes, the GPL 3 grants you the right to do this.

Looks, like they where real careful to not include any technical detail that would explain, how they manage to get that buildings stable and rain proof... Probably bullshit.
