Adf Function - 3M Speedglas 9100 Air User Instructions

ADF FUNCTION

™ ™
Should the 3M Speedglas Auto Darkening Filter (ADF) fail to switch to dark mode upon striking an arc, stop
welding immediately and inspect the ADF as described in these User Instructions. Continued use of an ADF that
fails to switch to the dark state may result in permanent eye injury and vision loss. If the problem cannot be
identifi ed and corrected, do not use the ADF; contact your supervisor, distributor or 3M for assistance.
The 3M ™ Speedglas ™ Welding Helmet 9100 Air and 3M
3M ™ Speedglas ™ ADF 9100 Series) are not suitable for laser welding or welding processes that require shade 14
or higher fi lters. Use of this product for these applications may result in permanent eye injury and vision loss.
Only operate the ADF at temperatures between 23°F (–5°C) and 131°F (+55°C). If used outside of this range,
the fi lter may not perform as designed and may result in permanent eye injury and vision loss.
On/Off
To activate the ADF, press the SHADE/ON button. The ADF automatically turns OFF after 1 hour of inactivity.
The ADF has three photo sensors that react independently and cause the fi lter to darken when a welding arc
is struck. The ADF 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 ADF making it fl ash when no welding is occurring. This
interference can occur from long distances and/or from refl ected light. Welding areas must be shielded from
such interference.
Shade
Seven different shade settings are available, split into two groups, 5, 8 and 9-13. In order to see the current
shade setting, momentarily press the SHADE/ON button. To change shade, press the SHADE/ON button
repeatedly. Move the fl ashing LED to the desired shade. To shift between the two shade groups (shade 5, 8) and
(shade 9-13), hold the SHADE/ON button down for 2 seconds. In all welding processes the arc should only be
viewed with the recommended dark shade (Table 2).

Sensitivity Selection
The programming and sensitivity of the photo detector system can be adjusted to accommodate a variety of
welding processes and workplace conditions. To change the sensitivity setting, press the SENS button repeatedly
until the LED shows the desired setting.
Position Light-State Lock (Grinding Mode) – switching function is disabled, remains in constant shade 3
Position 1 Least sensitive setting. Used if there is interference from other welders' arcs in the vicinity
Position 2 Default setting. Used for most types of welding, indoors and outdoors
Position 3 For welding with stable welding arcs (e.g., TIG welding)
Position 4 For low current TIG welding or inverter-type welding machines
Position 5 For TIG welding where part of the arc is obscured from view
Dark-State Lock – switching function is disabled, remains in selected dark shade
Position
Light-State Lock (Grinding Mode)
This setting is intended for grinding or other non-welding activities. When
the ADF is locked in the light state (shade 3) the LED under the symbol
will fl ash every 8 seconds to alert the user. The ADF must be changed to
an appropriate SENS setting before arc welding or it will remain in the
light-state lock mode. When the ADF turns off (after 1 hour inactivity), it will
automatically return to the default sensitivity setting 2.
Position 1-5
If the fi lter does not darken during welding as desired, increase the sensitivity until the ADF switches reliably.
Should the sensitivity be set too high, the fi lter may 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 ADF both darkens and lightens
appropriately.
Dark-State Lock (Plasma Cutting or Gas Welding
and Cutting)
This setting locks the ADF in the selected dark shade. If the ADF turns off
(after 1 hour inactivity), it will automatically return to the default sensitivity
setting 2.
Delay
The delay function allows the user to manually increase or decrease the recovery delay time (from dark to
light) according to the requirements of the welding process. The recovery time intervals are also automatically
extended as the shade increases. The time intervals are listed in milliseconds in Table 3. Although the Delay and
Sensitivity functions share the same LED display, they are separate adjustments.
2-Step Recovery
The two longest delay settings include an intermediate stage in the recovery.
As the arc extinguishes, the fi lter will briefl y recover to shade 5 and then to
shade 3. The time intervals for each stage are listed as d1 and d2 in Table 3.
