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.
Light-State Lock (Grinding Mode) – switching function is disabled, remains in constant shade 3.
Position
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 flash 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 filter does not darken during welding as desired, increase the sensitivity until the ADF switches reliably.
Should the sensitivity be set too high, the filter 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.
