SOLAR AUTO-DARKENING HELMET

READ & UNDERST AND ALL INSTRUCTIONS BEFORE USING

The ATD Auto-Darkening Welding Helmet is designed to protect the eye and face from sparks,
spatter, and harmful radiation under normal welding conditions. The auto-darkening filter
automatically changes from a light state to a dark state when an arc is struck, and it returns to
the light state when welding stops.

The ATD auto-darkening welding helmet comes ready for use. The only thing you need to do
before you weld is to adjust the position of the headband and select the correct shade number
for your application.

WARNING:

z The ATD auto-darkening welding helmet is not suitable for laser welding & oxyacetylene

welding / cutting processes.

z Never place the ATD helmet or the auto-darkening filter on a hot surface.
z Never open or tamper with the auto-darkening filter.
z The ATD auto-darkening welding helmet will not protect against severe impact hazards,

including grinding disks. Never use for grinding.

z This ATD helmet will not protect against explosive devices or corrosive liquids.
z Do not make any modifications to either the filter or helmet, unless otherwise specified in

this manual.

z Do not use replacement parts other than those specified in this manual. Unauthorized

modifications or replacement parts will void the warranty and expose the operator to the
risk of personal injury.

z Should the ATD helmet not darken upon striking an arc, stop welding immediately and

contact your supervisor or your dealer.

z Storing temperatures: -20°C ~ +70°C (-4°F ~ 158°F).
z Protect filter from contacting liquid and dirt.

z Clean filters’ surfaces regularly; use Windex or other mild cleaning solution. Always keep

sensors and solar cells clean using a clean lint-free tissue or cloth.

operating instructions.

TROUBLESHOOTING

z Irregular darkening or dimming

Headband has been set unevenly and there is an uneven distance from the eyes to the
filter’s lens (Reset the headband to reduce the difference to filter).

z Auto-darkening filter does not darken or flickers

• Front cover lens is dirty or damaged (change lens cover)

• Sensors are dirty (clean the sensors’ surface)

• Welding current is too low (turn the switch to the “slow” position).

z Slow response

Operating temperature is too low (do not use at temperature below -5°C or 23°F).

z Poor vision

• Front/inside cover lens and/or filter lens are dirty (Clean or change lens)

• There is insufficient ambient light

• Shade number is set incorrectly (reset the shade number)

z Welding helmet slips

Headband is not adjusted properly (readjust headband)

: Severe personal injury could occur if the user fails to

WARNING: User must stop using the auto-darkening welding

helmet immediately if the above-mentioned problems cannot be
corrected. Contact your ATD dealer immediately.

WARNING! Before using this helmet for welding ensure you have read and
understand the safety instructions

z The ATD auto-darkening welding helmet comes assembled but before it can be used it

must be adjusted to fit the user properly and set up for response time, se nsitivity and s hade
level.

ADJUSTING THE FIT OF THE HELMET

z The overall circumference of the headband can be made larger or smaller by rotating the

knob on the back of the headband. (See adjustment “Y” in fig.1)
This can be done while wearing the helmet to allow just the right tension to be set to keep
the helmet firmly on the head without it being too tight.

z If the headband is riding too high or too low on your head adjust the strap that passes over

the top of your head. To do this, release the end of the band by pushing the locking tab out
of the hole in the band. Slide the two portions of the band to a greater or lesser width as
required and push the locking tab through the nearest hole (See adju stme nt “W” in fig.1)

z Test the fit of the headband by lifting up and closing down the helmet a few times while

wearing it. If the headband moves while tilting, re-adjust it until it is stable.

z ADJUSTING DISTANCE BETWEEN HELMET & FACE

INSTRUCTIONS FOR USE

Step 1:

your face with the helmet in the down position.

Step 2:

your face. (See adjustment "Z" in fig.1) It is important that your eyes are each the same
distance from the lens otherwise the darkening effect may appear uneven.

Step 3:

Loosen the block nut (See "T" in fig.1) to adjust the distance between the helmet and

Loosen the block nut on either side of the helmet and slide it nearer to or further from

Re-tighten the block nut when adjustment is complete.
