For a small arc welder for a small job, is a mask really necessary?

yep, caught a case or arc-eye once from accidentally striking arc

I was moving to get in better position ... hurts like hell.

Just from ONE arc for a few seconds? That can't be true.

Well there's your answer - don't bother with a mask.

I caught a 1 second flash from a PCB exposure box (with no sodding
interlock!) and it diminished the colour perception in one eye for some
months.

How powerful are those things?

Mine's got a 15 watt UVB tube in it.
