KENNEDY thoroughly recommends reading these instructions before using the
welding helmet, even if you have used one before. Reading these instructions
carefully and understanding them fully will enable you to perform tasks correctly and
will prevent injury to yourself, someone else and avoid damage to property.
SAFETY GUIDELINES
Always follow the instructions or you may suffer physical injury or damage to property as a result.
Always be aware of health and safety regulations regarding welding.
Always wear correct eye and body protection.
Always keep away from fumes and work in a well ventilated area.
Always remove ill fitting clothing, ties, watches, rings, other loose jewellery and contain long hair.
Always ensure that the dark shade of the lens in the welding helmet is set to the correct shade
number for your application. (see page 6)
Always ensure that the helmet is clean and regularly inspected for breaks, cracking, pitting or
anything that may affect the operators vision. Should any of the mentioned occur the plate
should be replaced. Note: Please use identical replacement parts and accessories intended for
this tool, the use of other parts will void the warranty.
Always use machine guards or eye splash protection if the hazards of explosive devices or
corrosive liquids are being used as this helmet will not protect against these.
Always wear impact resistant primary eye protection, spectacles or goggles that meet current
ANSI specifications when using this welding helmet.
Always check your helmet fits properly.
Welding helmets are designed to protect the eyes and face from sparks, spatter and harmful
radiation under normal welding conditions. They will not protect against severe impact hazards,
including fragmenting grinding discs, and therefore must never be used for protection whilst grinding.
Never use this helmet and lens for 'overhead' welding application, laser welding, or laser cutting
applications.
Never make any modifications to the welding lens or helmet, use only genine kennedy
replacement parts or you will void warranty and expose the user to the risk of personal injury.
Never use work positions that could expose unprotected areas of the body to spark, spatter,
direct and/or reflected radiation. Use adequate protection if exposure cannot be avoided.
Never continue to use this helmet if the lens does not darken when striking the arc. Should this
occur you will need a new helmet and dispose of the old one in accordance with national and
local legislation.
Never immerse this product into water.
Never use any solvents on any lens or helmet components.
Never use this device beyond the recommended temperature limits. The recommended operating
temperature range for the welding lens is: 23°F - 131°F (-5°C to 55°C).
Never disassemble the filter, any problems arising, please contact your local Kennedy distributor.
Never operate when you are tired, under the influence of alcohol, drugs or intoxicating medication.
Never drop or use if damaged
WARNING: This Welding Helmet may not respond to a welding arc of OXY-Acetylene Plasma
cutting, Grinding, Laser welding or any welding below 20amps... These arc strikes are too
weak to be detected by sensors.

CHANGING THE LENS
This welding helmet must always be installed with an inner and outer protection plate
before welding. These may need replacing at some point.
To replace the lens/protection plates:
Firstly, remove the frame by pinching the retaining lugs together at the four positions on the
inside of the mask. This allows quick replacement of the two protection plates.
The filter lens assembly (2) is not replaceable and should it fail to function correctly the
helmet must be disposed of in accordance with national and local regulations .
CLEANING
This welding helmet should be cleaned regularly with a fine soft brush to remove dust and
particles. If absolutely necessary, you may clean the protection plates with soapy water
after removing them from the mask body. The filter lens assembly must not be cleaned with
water or any solvents. The mask body may be cleaned with a damp soft cloth, taking care
not to touch the filter lens assembly. Do not immerse in water.

This welding mask is designed using the latest technology to automatically protect the user’s
eyes from arc light damage and leave both hands free to increase accuracy, efficiency and
therefore productivity.
Fitted with automatic filters that are transparent before welding, it enables the operator to
observe the workpiece clearly. When striking the arc, the filter darkens automatically with
immediate effect. When the arc goes out, the filter will become transparent again. The
switching time from light to dark is approximately 1 millisecond, and the switching time from
dark to light maybe set at between 0.1 - 0.5 second.
The mask is equipped with a continuous darkness-adjusting unit, so the operator may select
an arbitrary darker shade number ranging from 9 to 13.
The mask also provides complete protection against UV/IR to DIN15 even in transparent
mode.
The mask is powered by 2 Lithium batteries and is equipped with two sets of photo sensors to
sense arc light.
The outer protection plate is made of high polymer materials that are spatter resistant and
thermostable, ensuring a long service life.

OPERATING INSTRUCTIONS
ASSEMBLY
Assemble the mask as shown in fig.4 opposite
POWER SUPPLY
Power supply is provided by 2 lithium batteries controlled with micro circuitry which
automatically turns the helmet on and off without having to touch a switch or button.
DARKNESS SELECTION
When you strike an arc, the observation window darkens immediately and at this moment
the operator needs to adjust the darkness shade by turning the knob to the optimum shade
for the current work being undertaken. (see table on page 6)
FITTING
All heads are different shapes and sizes, therefore it is important to adjust the headband to
fit and set at the correct observation angle. To do this, firstly adjust the skull strap (8) to
the correct position to locate the head gear pad (6) comfortably on your forehead. Secondly,
adjust the tightness by depressing and turning the tightness adjuster (7) to suit - do not
over tighten as this will cause headaches. Finally, loosen the locking nuts (12) to enable
you to pivot the mask to the desired viewing angle on the positioning plate (9), adjust the
horizontal position on the positioning clamp then tighten the locking nuts again.

SAFETY “TEST” BUTTON
The safety “TEST” button fig.1 is to safeguard you from damage to your eyes by testing the
ADF’s function prior to each use. (ADF = Auto Darkening Filter)
The normal signs of correct function are: the red light next to the button comes on for one
second and an immediate darkening of the lens. If this fails to happen do not commence
welding.
LOW BATTERY INDICATION
If any of the following happen, do not commence welding until after you have replaced the
batteries (advisable once a year)
The Red light flickers, the lens is constantly dark, or when tested the 2 battery voltages are
less than 2.5v.
To replace the batteries, unscrew the screw shown in fig.2 to release the battery holder as
shown in fig.3. Remove the old batteries and replace with two new 3v CR2032 batteries with
the + positive side up on both. Refit the holder and replace the screw.
Re-test prior to welding. If the helmet is still not functioning correctly, have it checked out by a
qualified technician or return to your local KENNEDY distributor.
