Shade (Dark State): Variable shade, commonly DIN 5–9 or DIN 9–13 depending on model.

Light (Clear) State: Usually around DIN 3 or DIN 4 in light / grind mode.

Switching Time (Light → Dark): Very fast: for example, 1/10,000 s in some models.

Delay Time (Dark → Light): Adjustable delay (recovery) — e.g., 0.1 s to ~1.0 s.

Number of Arc Sensors: Commonly 2–4 sensors to detect the welding arc.
