What is the typical filter lens range for GTAW-P work?

Explanation:
GTAW-P welding uses an exceptionally bright plasma/TIG arc, so the lens shade must be dark enough to protect the eyes while still letting you see the weld pool clearly. In most GTAW-P tasks, a filter lens in the middle range—shade 10 to 12—is used. This level provides solid protection for the bright arc without overly darkening the view, which would make it hard to see the weld detail or the root of the bead. Lower shades (more permissive protection) wouldn’t cover the glare from the plasma arc, while much higher shades would impede visibility and slow your work. If you’re welding very low-current, thinner material, you might stay around shade 10; for higher currents or thicker work, shade 12 is common.
