button for two seconds. The 9002D, 9002V and 9002X ADFs have an extra feature: After each short press of the
ON button, the current settings (shade, sensitivity and delay) are displayed by flashing LED’s.
Dark Shade Selection
(9002D, 9002V and 9002X only)
Up to five different dark shade levels are available to the user: 9, 10, 11, 12 and 13, depending on the ADF model.
Check with the Shade Guide below to determine the proper dark shade setting for your application. In order to see
which shade the welding filter is currently set to, momentarily press the shade button. To select another shade,
keep pressing the shade button while the LED is flashing until the LED indicates the desired setting.
Sensitivity Selection
(9002D, V and X ADFs)
The photo-sensor system detects the welding arc and triggers the ADF to switch to the dark state. The sensors are
designed to respond welding arcs and not to normal ambient lighting or sunlight. To change the sensitivity setting,
press the sensitivity button repeatedly until the LED indicates the desired setting.
9002V and X:
Position 1
Low sensitivity - for welding in groups.
Position 2
Normal sensitivity - for typical SMAW, MIG and TIG welding indoors and outdoors.
Position 3
High sensitivity - for low current or stable arcs (e.g. TIG welding at low amps)
Position 4
Very high sensitivity - for very low current, stable arcs and partially blocked arcs
9002D:
Low:
Normal sensitivity - for typical SMAW, MIG and TIG welding indoors and outdoors.
High:
High sensitivity - for low current or stable arcs (e.g. TIG welding at low amps)
Finding the right sensitivity setting
(9002V and X ADFs)
In order to find a suitable sensitivity setting, start with setting 2. This is the correct setting for most applications. If
the filter does not darken reliably while welding, change to setting 3 or 4 until reliable switching is achieved. If
the sensitivity is set too high, the filter might switch to the dark state in response to ambient lighting. If the ADF
is being used in close proximity to other welding arcs, it may be necessary to switch to position 1 to avoid
interference or "false triggering."
Setting the Delay
The delay setting controls the speed at which the filter returns to the light state after welding has stopped. In order
to see which position it is currently set to, momentarily press the delay button. To select another setting, keep
pressing the delay button while the LED is flashing until the LED indicates the desired setting.
Position
─
Fast recovery to light state - for spot or tack welding where the welder needs to have a clear view
quickly after finishing the weld.
Position
│
Normal position.
Po
Delayed recovery to light state - for high amperage applications where bright weld pools must
cool briefly before viewing.
Gas Welding and Cutting
3M™ Speedglas™ ADFs can be used for gas welding and cutting when in the OFF state. The ADF is shade 5-6
when OFF.
