Product Features/Operation

At the moment the welding operation is started, the filter screen automatically changes from clear to dark in only 1/25,000th of a second.

Dark to clear delay adjustment: Operator can vary the time for the filter to return to clear state. At the moment welding is stopped, the filter screen automatically changes from dark to clear state according to the time setting you select.

Switch Sensitivity Adjustment: The operator can adjust the amount of light needed to cause the Lens to darken.

This Welding Helmet utilizes high performance solar cells as power supply, and has built-in battery(ies) as power backup, see below. Under normal welding conditions, users can expect a battery lifetime of more than 6 years.

User-selectable (DIN) variable shades from 9 to 13 are adjusted at the turn of a shade knob (shade variable). This product is in full conformity with related DIN, ISO, EN379 safety standards and ANSI Z87.1-1989 standard.

The ultra high performance of UV and IR Auto-Darkening filters provides to the user’s eyes and face full protection against UV and IR radiation during the entire welding process, even in the clear state. The UV/IR protection level is up to Shade 16 (DIN) at all times.
