HELMET CARE AND MAINTENANCE

Virtually maintenance free:

• Periodic cleaning with soapy water solution or standard glass

cleaner is suggested for any ADF to function properly. Use soft
cloth or eye glass wipes.

• This ADF is water resistant. Do “NOT” submerge in water or other

solution.

• Change or clean cover lens when it becomes dirty or cloudy.

Storage:

• Store in a clean dry location.

TROUBLE SHOOTING GUIDE

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.

Difficult to see through the filter:

• Clean or replace protective cover lenses.
• Clean the Auto-Darkening cartridge by using a cloth with soapy

water solution or standard window cleaner.

The ADF will not darken after striking an arc:

• Avoid blocking the Solar Panels. Must be facing forward (outside

of) in the helmet.

• Test the ADF by exposing to a bright light source and run your fin-

gers quickly over the arc sensors. The filter should darken momen-
tarily then switch back to the light state.

Slow to darken:

• If the filter has not been used for a day or more, the circuitry will

enter a sleep mode. It will wake up when tested or when you begin
welding. Note that the first time, it may darken to a lighter shade
even though set for a darker shade. After the first time, it will dark-
en to the correct shade setting every time. It is recommended to
test your ADF prior to welding.

• Colder temperatures can slow the switching speed of any ADF.

Once the helmet warms up from the welding process, the switching
will increase to rated speeds.

ADF (Auto-Darkening Filter Cartridge) flickers or returns to light state
while welding:

• Clean or replace protective cover lenses if dirty or cloudy.
• Check that the solar panels or sensors are not damaged or dirty.

Clean with a soft cloth and soapy water solution or standard glass
cleaner. Do not use abrasive or dirty cloths.

• Make sure you are not blocking the sensors or solar panels with

your arm or other obstacle (including the welding torch gun or noz-
zle) while welding. Adjust your position so that the sensors can
“see” the weld arc.
