• SENSITIVITY
The sensitivity can be set to " H "(high) or " L "(low) by using the infinitely dial knob on the back of the shade cartridge.
The "Mid-High" setting is the normal setting for everyday use. The maximum sensitivity level is appropriate for low wel-
ding current work, TIG, or special applications. Where the operation of the helmet is disturbed by excess ambient light,
or another welding machine close by, use the "low" setting (See fig.3b). As a simple rule for optimum performance, it
is recommended to set sensitivity to the maximum at the beginning and then gradually reduce it, until the filter reacts
only to the welding light flash and without annoying spurious triggering due to ambient light conditions (direct sun,
intensive artificial light, neighbouring welder's arcs etc.).
• BATTERY INSTALLATION
Install batteries into helmet properly, according to positive and negative terminal marking on battery jar (See fig.5).
• TEST
Press and hold test to preview shade selection before welding (See fig.5). When released then viewing window will
automatically return to the light state (3.5 Shade).
• POWER
This ADF cartridge is powered by solar cell and 2 AAA Alkaline batteries. Replace batteries when LOW BATTERY light is
lit (See fig.5).
• You are now ready to use the helmet. The shading may be adjusted during use by re-setting potentiometer control.
