As far as blind tacking I probably have made a million of them with a stick welder by holding the welding rod between my fingers (With welding gloves!) to form a shield a few inches from the tip of the rod thus providing protection from the arc rays, still can't see what I am doing but like you said after a while it becomes second nature. Also have you tried the little shield attachment that clamps to the MIG gun that has a dark lens? It is kind of clumsy but there was a couple of times I managed to make some otherwise nearly impossible welds using one because of cramped space limiting room for a regular helmet. This thing does eliminate the problem of direct UV exposure when someone just turns their head or closes their eyes, this can cause problems over time if done often enough.
