Welding Helmet
AB8550SGC

• This Auto-Darkening welding helmet is not suitable for laser welding and oxyacetylene
welding / cutting processes.
• Never place this helmet and Auto-Darkening filter on a hot surface.
• Never open or tamper with the Auto-Darkening filter.
• This Auto-Darkening welding helmet will not protect against severe impact hazards.
• This helmet will not protect against explosive devices or corrosive liquids.
• Don´t make any modifications to either the filter or helmet, unless specified in this manual.
Don´t use replacement parts other than those specified in this manual. Unauthorized
modifications and replacement parts will void the warranty and expose the operator to the
risk of personal injury.
• Should this helmet not darken upon striking an arc, stop welding immediately and contact
your supervisor or your dealer.
• Don´t immerse the filter in water.
• Don´t use any solvents on the filter screen or helmet components.
• Use only at temperatures: -10º C ~ +55º C (14°F ~ 131°F).
• Storing temperature: -20º C ~ +70º C (- 4°F ~ 158°F). The helmet should be stored in dry
cool and dark area, when not using it for a long time.
• Protect filter from contact with liquid and dirt.
• Clean the filter surface regularly; don´t use strong cleaning solutions. Always keep the
sensors and solar cells clean using a clean lint-free tissue.
• Regularly replace the cracked / scratched / pitted front cover lens.
• The materials which may come into contact with the wearer’s skin can cause allergic
reactions in some circumstances.

SAFETY WARNINGS - READ BEFORE USING

Auto-Darkening welding helmets are designed to protect the eye and face from sparks,
spatter and harmful radiation under normal welding conditions. 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.
Auto-Darkening welding helmets come ready for use. The only thing you need to do before
your welding is to adjust the position of the headband and select the correct shade number
for your application.

COMMON PROBLEMS AND REMEDIES
• Irregular Darkening Dimming
Headband has been set unevenly and there is an uneven distance from the eyes to the
filter lens (Reset the headband to reduce the difference to the filter).
• Auto-Darkening filter does not darken or flickers
① Front cover lens is soiled or damaged (Change the cover lens).
② Sensors are soiled (Clean the sensors surface).
• Slow response
Operating temperature is too low (Do not use at temperatures below -10º C or 14º F).
• Poor vision
① Front / inside cover lens and / or the filter is soiled (Change lens).
② There is insufficient ambient light.
③ Shade number is incorrectly set (Reset the shade number).
④ Check if removing the film on the front cover lens.
• Welding helmet slips
Headband is not properly adjusted (Readjust the headband).
WARNING
The user must stop using the auto-darkening welding helmet immediately
if the above-mentioned problems cannot be corrected. Contact the dealer.
INSTRUCTIONS FOR USE
WARNING! Before using the helmet for welding, ensure that you have
read and understood the safety instructions.
WARNING
Severe personal injury could occur if the user fails to follow the above
mentioned warnings and/or fails to follow the operating instructions.

• The helmet comes ready assembled but before it can be used it must be adjusted to fit
the user properly and set up for delay time, sensitivity and shade level.
• ADJUSTING THE FIT OF THE HELMET
TSensitivityhe overall circumference of the headband can be made larger or smaller by
rSensitivityotating the knob on the back of the headband (See adjustment “Y” in fig.1).
This can be done whilst wearing the helmet and allows just the right tension to be set to
keep the helmet firmly on the head without it being too tight.
• If the headband is riding too high or too low on your head, adjust the strap which passes
over the top of your head. To do this, release the end of the band by pushing the locking
pin 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 pin through the nearest hole (See adjustment “W”
in fig.1).

• 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.
• ADJUSTING THE DISTANCE BETWEEN THE HELMET
AND THE FACE
Step 1: Undo the block nut (See “T” in fig.1) to adjust the
distance between the helmet and your face in the down
position.
Step 2: Loosen the block nut on either side of the helmet and
slide it nearer or further from 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: Re-tighten the block nut when adjustment is complete.
• ADJUSTING VIEW ANGLE POSITION
Please see fig.2.
• SELECTING SHADE LEVEL
Select the shade level you require according to the welding
process you will use by referring to the “Shade Guide Table”
below for settings. Turn the shade control knob on the side of
the helmet to the shade number required.
• SELECTING THE GRIND OPTION
When the shade knob is turned to the “Grind” position, the
shade function is turned off allowing a clear view to grind a
weld with the helmet providing face protection. Before restarting
welding work, Ensure that the shade function is turned back on
before welding again (See fig.3).
• You are now ready to use the helmet. The shading may be adjusted during use by
re-setting the potentiometer control.

• REPLACE THE FRONT COVER LENS. Replace the front cover lens if it is damaged
(cracked, scratched, dirty or pitted) Place your finger or thumb into the recess at the bottom
edge of the wirdow and flex the window upwards until it releases from one edge (See fig.4).
• REPLACE THE INNER COVER LENS. If it is damaged (cracked, scratched, dirty or pitted).
• CHANGING THE SHADE CARTRIDGE (See figs.5a & 5b).
• INSTALLING NEW CARTRIDGE. Take the new shade cartridge and pass the potentiometer
cable under the wire loop before dropping the cartridge into its retaining frame inside the
helmet. Press down the wire loop clip and ensure that the front edge of the loop is properly
retained under the retaining lugs as shown in fig.5b.
• Fasten the potentiometer to the inside of the helmet with the shaft protruding through the
hole. Push the shade control knob onto the shaft.
• CLEANING. Clean helmet by wiping with a soft cloth. Clean cartridge surfaces regularly.
Do not use strong cleaning solutions. Clean sensors and solar cells with methylated spirit
and a clean cloth and wipe dry with a lint-free cloth.
