Important Safety Information

Page 6 of 16
⚠WARNING
WORK AREA SAFETY
 Inspect the work area before each use. Keep work area clean, dry, free of clutter, and well-lit.
Cluttered, wet, or dark work areas can result in injury. Using the product in confined work areas
may put you dangerously close to cutting tools and rotating parts.
 Do not use the product where there is a risk of causing a fire or an explosion; e.g., in the presence
of flammable liquids, gases, or dust. The product can create sparks, which may ignite the
flammable liquids, gases, or dust.
 Do not allow the product to come into contact with an electrical source. The tool is not insulated
and contact will cause electrical shock.
 Keep children and bystanders away from the work area while operating the tool. Do not allow
children to handle the product.
 Be aware of all power lines, electrical circuits, water pipes, and other mechanical hazards in your
work area. Some of these hazards may be hidden from your view and may cause personal injury
and/or property damage if contacted.
⚠WARNING
PERSONAL SAFETY
 Stay alert, watch what you are doing, and use common sense when operating the tool. Do not use
the tool while you are tired or under the influence of drugs, alcohol, or medication. A moment of
inattention while operating the tool may result in serious personalinjury.
 Dress properly. Do not wear loose clothing, dangling objects, or jewelry. Keep your hair, clothing
and gloves awayfrom moving parts. Loose clothes, jewelry, or long hair can be caught in moving
parts. Air vents on the tool often cover moving parts and should be avoided.
 Wear the proper personal protective equipment when necessary. Use ANSI Z87.1 compliant safety
goggles (not safety glasses) with side shields, or when needed, a face shield. Use a dust mask in
dusty work conditions. Also use non-skid safety shoes, hardhat, gloves, dust collection systems,
and hearing protection when appropriate. This applies to all persons in the work area.
 Do not overreach. Keep proper footing and balance at all times.
 Remove keys or wrenches before connecting the tool to an air supply, power supply, or turning on
the tool. A wrench or key that is left attached to a rotating part of the tool may cause personal
injury.
 Secure the work with clamps or a vise instead of your hand when practical. This safetyprecaution
allows for proper tool operation using both hands.

⚠CAUTION
WELDING HELMET USE AND CARE
 Do not force the welding helmet. Products are safer and do a better job when used in themanner
for which they are designed. Plan your work and use the correct product for the job.
 Check for damaged parts before each use. Carefully check that the product will operate properly
and perform its intended function. Replace damaged or worn parts immediately. Never operate the
product with a damaged part.
 Do not use a product with a malfunctioning switch. Any power tool that cannot be controlled with
the power switch is dangerous and must be repaired by an authorized service representative
before using.
 Disconnect the power/air supply from the product and place the switch in the locked or off position
before making any adjustments, changing accessories, or storing the tool. Such preventive safety
measures reduce the risk of starting the tool accidentally.
 Store the product when it is not in use. Store it in a dry, secure place out of the reach of children.
Inspect the tool for good working condition prior to storage and before re-use.
 Use only accessories that are recommended by the manufacturer for use with your product.
Accessories that may be suitable for one product may create a risk of injury when used with
another tool. Never use an accessorythat has a lower operating speed or operating pressure than
the tool itself.
 Keep guards in place and in working order. Never operate the product without the guards inplace.
 Do not leave the tool running unattended.
⚠WARNING
 To prevent serious injury or property damage, read and understand owner’s manual before
operating.
 Before welding or cutting, ensure the darkness range of this helmet offers enougheye
protection for your use.
 Always wear ANSI Z87.1 compliant eye protection along with the welding helmet duringuse.
The front cover lens (front impact resistant plate) CAN BREAK and DOES NOT provide
complete protection against flying particles, splash, spray and splatter.
 Inspect lens before each use. Pitted or scratched lens plates reduce vision clarity, severely
reduce impact protection and should be replaced immediately to prevent injury.
 Not for use with laser welding processes.
 Inspect the helmet before each use. Do not use if damaged. Replace worn parts beforeusing.
 Not for use by children. Store helmet out of the reach of children.

Operating Instructions

Page 9 of 16
Before Welding
The Auto-Darkening Welding Helmet comes ready for use. Prior to first use, remove the protective
film from both sides of the lens (if not already done), adjust the position of the headband, select the
correct shade number for the welding application, and test the helmet for proper operation as
described below. Check the Front Lens Cover to make sure that it is clean, and that no dirt is
covering the four sensors on the front of the Filter Cartridge. Also check the Inside Lens Cover and
the Lens Retaining Frame, and make sure that they are secured in place. Inspect all operating parts
before each use for signs of wear or damage. Any scratched, cracked, or pitted parts should be
replaced immediately before using again to avoid severe personal injury.
Shade Number and Grinding Mode Selection
1. Select weld/cut/grind mode by the switch (Fig. B - 4), then set the shade number required (see
Shade Guide Chart on page 4) by turning the Shade Control Knob (Fig. B - 2). Be sure that the
shade number of the Welding Helmet is the correct shade number for your application.
Note: If a selection of shade is recommended for your application, try the darkest setting first.
2. Setting the sensitivities depend on your welding work, see page 5 Sensitivity Setting Guide.
Cut/Weld Mode: Use control to make the lens more responsive to different light levels in
various welding/cutting processes. Use a Mid-Range or 30%-50% sensitivity setting for
most applications. It may be necessary to adjust helmet sensitivity to accommodate different
lighting conditions or if lens is flashing On and Off.
Grinding Mode: Do not weld in the Grind mode, the lens will not darken.

Time Delay Setting
At the moment the welding operation is started, the filter screen automatically changes from clear to
dark. The operator can set the delay time by turning the Delay Control Knob (Fig. B - 3).
Important: Test the helmet auto-darkening filter lens before welding. While wearing the helmet,
briefly strike an arc, keeping your face and eyes turned slightly away, and to one side. The lens
should darken evenly when not directly facing the arc. If it does not darken properly, do not use
the Welding Helmet.
Grinding Mode Setting
To change to Grinding Mode, set the mode to Grind by the switch (Fig. B - 4).
CAUTION! Set the helmet to the proper shade setting before welding again.
Adjusting Headband
Adjust the Headband so that the helmet is seated securely on your head as low as possible and
close to your face.
Adjust the Headband width by turning the Headband Adjustment Knob to make sure the Front Lens
Cover is aligned with your eyes.
Adjust the Headband height by tightening or loosening the top strap until the Helmet fits snug on
your head. Once the Headband is properly adjusted, lower the Helmet over your face until the
proper angle is found. Then turn the Tension Adjustment Knobs on either side of the helmet, locking
the helmet’s angle in place.
