Important Safety Information
⚠WARNING
•Read and understand all instructions. Failure to follow all instructions may result in serious injury
or property damage.
•The warnings, cautions, and instructions in this manual cannot cover all possible conditions or
situations that could occur. Exercise common sense and caution when using this tool. Always be

Page 5 of 14
aware of the environment and ensure that the tool is used in a safe and responsible manner.
•Do not allow persons to operate or assemble the product until they have read this manual and
have developed a thorough understanding of how it works.
•Do not modify this product in any way. Unauthorized modification may impair the function and/or
safety and could affect the life of the product. There are specific applications for which the product
was designed.
•Use the right tool for the job. DO NOT attempt to force small equipment to do the work of larger
industrial equipment. There are certain applications for which this equipment was designed. This
product will be safer and do a better job at the capacity for which it was intended. DO NOT use
this equipment for a purpose for which it was not intended.
•Industrial or commercial applications must follow OSHA requirements.
⚠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 personal injury.
•Dress properly. Do not wear loose clothing, dangling objects, or jewelry. Keep your hair, clothing
and gloves away from 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.

Page 6 of 14
•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 safety precaution
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 the manner
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 accessory that 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 in place.
•Do not leave the tool running unattended.
Specific Operation Warnings
⚠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 enough eye protection
for your use.

Step 1. Tear off the protective film inside and outside the surfaces of the lens.
The filter screen is in a transparent and clear state, enabling a clear vision on the work piece. At the
start of welding, it AUTOMATICALLY changes the filter screen from clear to dark. The moment the
welding is complete, the filter screen AUTOMATICALLY changes from a dark to clear state. Adjust
the shade number knob under the weld mode, according to the welding current.
Step 2. Select the operating mode.
1. Weld Mode: Turn the dial clockwise from DIN9--DIN13 (shade number) on the left side of the
helmet (image below).
2. Grind Mode: Turn the dial to Grind Mode while the Weld Mode is turned off.
Step 3. Turn the dial to select the shade number.
1. Adjust the shade number from DIN9--DIN13 using the dial under the Weld Mode, according to
welding current and welding type.

2. Select the shade level. Before welding, carefully read through the Shade Guide Table below and
adjust the lens.
a) Verify the welding process.
b) Check the arc current on your equipment (from 0.5—500 amps).
c) Choose the correct shade (Din number) below and adjust the helmet before welding.
Step 4. Adjust the fit of the helmet.
1. Turn the headband until the adjustable knob is in the rear position. Manually press, and at the
same time, rotate the adjustable knob counter-clockwise to increase the circumference of the
headband. Rotate the knob clockwise to decrease the circumference.

2. To adjust the distance between the helmet and your face, loosen the knob on the headband and
move the block nut in or out.
•Move the block nut out and the helmet will be further from your face.
•Move the block nut in and the helmet will be closer to your face.
3. To adjust the overhand band to one of the custom fit positions for proper helmet depth, rotate the
dial on the back of the headband.
•Press the spring-activated dial on the headband and turn left to loosen.
•Press the spring-activated dial on the headband and turn right to tighten.
After Each Use
After a welding job is complete, turn the dial to Grind Mode on the helmet and store the helmet in a
dry and dark environment.
Maintenance
Maintain the welding helmet by adopting a program of conscientious repair and maintenance in
accordance with the following recommended procedures.

Page 11 of 14
•Clean the helmet by wiping it with a soft cloth. Clean cartridge surfaces regularly. Do not use
strong cleaning solutions. Clean sensors and solar cells with a damp cloth with methylated spirit
(denatured alcohol) and a clean, lint-free cloth. Wipe dry with a separate clean, lint-free cloth.
•Replace the front cover lens and inner cover lens if they are cracked, scratched, dirty, or pitted.
Place your finger or thumb into the recess at the bottom edge of the window and flex the window
upward until it releases from one edge.
•Clean the welding lens with a clean, lint-free tissue or cloth with residential glass detergent. Do not
immerse in water or other liquids.
•Use neutral detergent to clean headband. Never use solvents or oil to dilute detergent.
