Note!
Flashing light sources (e.g. safety strobe lights) can trigger the welding fil-
ter making it flash when no welding is occurring. This interference can occur
from long distances and/or from reflected light. Welding areas must be shiel-
ded from such interference.
Caution!
Should the Speedglas SL welding shield fail to switch to the dark state upon
ignition of an arc, stop welding immediately and inspect the welding filter as
described in these instructions. Continued use of the welding filter that fails
to switch to the dark state may cause temporary vision loss. If the problem
cannot be identified and corrected, do not use the welding filter, contact your
supervisor, distributor or 3M for assistance.
