A good rule of thumb would be: if you can see it at all, you are too close
for anything but a quick glance.

Is there any rule of thumb on how close I can be and still safely watch
(not a casual glance) arc welding without any eye protection? Does
this distance vary by amperage or type (stick, wire, TIG, etc.)?
