Which lens shade range is typical for GTAW-P?

Explanation:
GTAW-P uses a plasma arc, which is extremely bright and emits a lot of UV/IR radiation. To protect your eyes from this intense light, you need a darker lens shade than you’d typically use for milder TIG welding. That means selecting a shade range toward the higher end of the TIG shading options, which reduces glare and shields the eyes from radiant energy while still keeping enough visibility to work safely. In short, GTAW-P requires a darker filter than standard TIG, making the darker end of the shade range the best fit.
