Product details:

External shade adjustment between DIN 9 and DIN 13 and optical class 1/2/1/2. ; Delay and sensitivity can be adjusted from the inside. ; Four arc sensors for higher response and wider coverage and a large viewing area of3.85 x 1.88 in. (98 x 48 mm); wider field of vision and increased spatial awareness; Sensitivity control is an adaptable feature useful when welding low amperages (GTAW) for better reto darker arc light. ; Delay control enabling the welder to set how long the lens stays dark after the welding arc stops. Short delay helps get the job done faster during tack welding, whilst longer delay is useful for high amperage welding.
