Auto-Darkening Filter Function; Preparation For Use - 3M Speedglas G5-02 Instrucciones De Uso

Auto-Darkening Filter Function

1. Should the 3M™ Speedglas™ Auto-Darkening Filter G5-02 fails to switch to dark mode upon striking
an arc, stop welding immediately and inspect the welding filter as described in these User Instructions.
Continued use of a welding filter that fails to switch to the dark state may result in permanent eye
injury and vision loss. If the problem cannot be identified and corrected, do not use the welding filter;
contact your supervisor, distributor or 3M for assistance.
2. Carefully inspect the complete 3M™ Speedglas™ Auto-Darkening Filter G5-02 before each use. Cracked,
pitted or scratched filter glass or protection plates reduce vision and can seriously impair protection. All
damaged components should be replaced immediately. Remove any protective film from the welding filter
before initial use.
3. The 3M™ Speedglas™ Auto-Darkening Filter G5-02 is not suitable for laser welding or welding
processes that require filters greater than Shade 12. Likewise, the G5-02 is not suitable for grinding.
Use of this product for these applications may result in permanent eye injury, vision loss, and other
serious injury.
4. Only operate the welding helmet at temperatures between 23°F (–5°C) and 131°F (+55°C). If used
outside of this range, the system may not perform as designed and may result in serious bodily injury,
sickness or death.

Preparation for Use

On/Off
The welding filter is motion sensitive and will automatically turn ON when moved. During its initial power-up,
all of the adjustment lights will cycle quickly, one at a time. The welding filter automatically turns OFF after
1 hour of inactivity. The welding filter has four photo sensors that react independently and cause the filter to
darken when a welding arc is struck (Fig. 5). The welding filter may not turn dark if the sensors are blocked
or the welding arc is totally shielded. Flashing light sources (e.g. safety strobe lights) can trigger the welding
filter making it darken 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.
