AUTO-DARKENING CARTRIDGE CONTROLS:

VISTA™ - 4 x 5 ADF include Variable Shade, Sensitivity and Delay.

To make adjustments to your ADF controls, push appropriate button through
clear protective lens
until desired setting is achieved. There is no need to
disassemble helmet to access control buttons on your ADF cartridge. Simply
press directly on the inside cover lens to change button settings.

Test your ADF filter prior to welding by directing the front of the filter toward a
bright source of light, then using your fingers rapidly cover and uncover the
sensors. The filter should darken momentarily as the sensor is exposed. A
torch striker can also be used.

SENSITIVITY MODE

Select the sensitivity of the filter by pushing the Sensitivity button. You can
choose Grind, Normal or TIG.

Grind mode allows you to use the filter with a constant shade when grinding,
so that raising the helmet is unnecessary. Set Grind mode by pressing and
holding down the button until the filter LCD flickers. To remove from Grind
mode press the button again (note: the filter will not flicker).

Normal mode (no LEDs are on) is recommended for general welding and
production welding (i.e. where welders are welding in close proximity to each
other).

Set Normal mode by pressing button until no LEDs are on (Grind

and TIG LED are not on).

TIG mode is recommended for situations where the filter may be temporarily
blocked or the welding amperage is low. Set TIG mode by pressing button
until TIG LED is on.
