In order to see the current sensitivity setting, momentarily press the Sensitivity button. To select another setting, press the Sensitivity button again while the LED is flashing, and continue to press until the LED shows the desired setting. Position 1 Least sensitive setting. Used if there is interference from other welders’ arcs in the vicinity. Position 2 Normal position. Used for most types of welding indoors and outdoors. Position 3 Position for welding with low current or with stable welding arcs. (eg TIG welding) Position 4 Extreme photo detector sensitivity. Suitable for very low current welding, use of inverter-type TIG welding machines or pipe welding where part of the arc is obscured from view. Finding the right Sensitivity setting In order to find a suitable sensitivity setting, start with the setting, before welding, in Position 2. This is the default position that functions in the majority of situations. If the filter does not darken during welding as desired, raise the sensitivity to Position 3 or 4 until the welding filter switches reliably. Should the sensitivity be set too high, it is possible that the filter will remain in the dark state after welding is complete due to ambient light. In this case, adjust the sensitivity downward to a setting where the welding filter both darkens or lightens as desired. Low battery indicator The battery should be replaced when the low battery indicator flashes or shade and sensitivity LEDs do not flash when the buttons are pushed. Note! The welding filter may not go to dark position if the sensors are blocked or the welding arc is totally shielded. i1 Note! Flashing light sources (e.g. safety strobe lights) can trigger the welding filter making it flash when no welding is occurring. This interference can occur from long distances and/or from reflected light. Welding areas must be shielded 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. MAINTENANCE Replacement of outer protection plate. Remove the used outer protection plate and place the new outer protection plate on the welding shield as indicated in f ffi iig ggu uur rre ees ss C CC: ::1 11– –– C CC: ::2 22. .. Note!

The headband can be replaced according to f ffi iig ggu uur rre ee F FF: ::1 11– ––F FF: ::2 22. .. Replacement of battery. The welding filter must be removed to acess the battery compartment. Take out the battery holder (use a small screwdriver if necessary). 1i Remove the used batteries and dispose of them according to local regulations. Insert new batteries in the battery holder according to f ffi iig ggu uur rre ee G GG: ::1 11. .. Slide the battery holder into the welding filter until it snaps in position. Temperature range The recommended operating temperature range for the welding filter is -5°C to +55°C. Store in a clean and dry environment, temperature range -30°C to +70°C. Inspection Carefully inspect the complete Speedglas SL welding shield assembly frequently and replace worn or damaged parts. Cracked, pitted or scratched filter glass or protection plates reduce vision and can seriously impair protection. Replace necessary parts immediately with new authentic Speedglas brand parts to avoid damage to the eye and face. The sensors on the welding filter must be kept clean and uncovered at all times for correct function. Note! To check that the electronics and buttons are working, press the buttons and the LEDs will flash. Cleaning Clean the shield with a mild detergent and lukewarm water. Do not use solvents. Clean the welding filter with a clean lint-free tissue or cloth. Do not immerse in water. Caution! Use this welding shield ONLY for face and eye protection against harmful radiation, sparks and ...
