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.

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.

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
