INSTRUCTIONS for

Eye-Tech 11 Mono

Welding Helmet

P/N 15F22

ARC RAYS can burn eyes and skin. Wear safety

glasses and set proper filter shade. See ANSI/AWS

Z49.1 for guide. Available from American Welding

Society, Miami, FL 33135.

The Eye-Tech 11 Mono welding helmet is delivered fully

assembled and ready for use. You only need to adjust

the headband. The shade cartridge automatically dark-

ens to a shade 11 with arc ignition. The normal shade

before an arc is struck is 4 DIN.

Safety Precautions

z Pitted or scratched plates reduce vision and protec-

tion. Replace worn or damaged parts immediately.

z Always keep the external and internal protective plates

in place. Failure to do so will allow welding spatter to

pit the front surface of the shade cartridge. This can

reduce the built-in UV and IR protection. (Also, the weld

spatter will void the warranty on the shade cartridge.)

z Do not attempt to open the shade cartridge.

z Do not use in cold weather (below 14° F).

z Keep solar cells clean. Clean with a damp not wet, cloth

dipped in soapy water. Dry with a soft, clean cloth.

z Do not drop, strike, or bend helmet.

z Do not use abrasive cleaning agents.

z Fumes and gases can be hazardous to your health.

Keep your head out of the fumes. Ventilate area or use

breathing devices, if necessary.

z Keep helmet dry (especially the shade cartridge) and

do not place on hot surfaces.

Operation

z Check to see if the front cover lens is inserted and front

lens frame is in place.

z Adjust the headband tension. The helmet is ready to use.

The cartridge will darken with arc ignition.

Troubleshooting

z Uneven darkening

- Protective helmet is not on straight, causing the dis-

tance between your eyes and the shade cartridge to

vary. If necessary, decrease distance to shade car-

tridge.

z The shade cartridge does not darken or it flickers

- Sensors are dirty; clean

- Front cover lens is dirty or damaged; clean or replace

- Welding current is too low

z Slow switching times

- Temperature is too low (should not be below 14° F)

- Lighting is insufficient

z Poor visibility

- Shade levels are set incorrectly

- Front or rear cover lens is dirty

- Room lighting is insufficient

z Welding helmet slips

- Headband is not properly adjusted (set too low)

If these faults cannot be corrected, do not use

helmet. Contact your distributor for assistance.

The Eye-Tech 11 Mono Welding Helmet, P/N 15F22, is a personal protective device designed for welding applications. Its primary function is to shield the user's eyes and face from the harmful effects of arc rays, including intense visible light, ultraviolet (UV) radiation, and infrared (IR) radiation, which are generated during welding. The helmet incorporates an automatic darkening filter (ADF) that transitions from a light state (Shade 4 DIN) to a darker, protective shade (Shade 11) milliseconds after an arc is ignited. This automatic darkening feature eliminates the need for the welder to manually flip the helmet down, improving efficiency and reducing neck strain.

Function Description:

The core functionality of the Eye-Tech 11 Mono Welding Helmet revolves around its automatic darkening shade cartridge. This cartridge is equipped with sensors that detect the sudden increase in light intensity when a welding arc is struck. Upon detection, the liquid crystal display (LCD) within the cartridge rapidly darkens to Shade 11, providing immediate protection to the welder's eyes. When the arc ceases, the cartridge automatically returns to its light state (Shade 4 DIN), allowing the welder to see their work area clearly without removing the helmet. This seamless transition enhances productivity and safety by ensuring continuous visibility and protection. The helmet also provides constant protection against UV and IR radiation, even in its light state, safeguarding the eyes from long-term damage.

Usage Features:

The Eye-Tech 11 Mono Welding Helmet is delivered fully assembled and ready for immediate use, requiring only a simple headband adjustment.

Automatic Darkening: The helmet's primary user-friendly feature is its automatic darkening function. Welders do not need to manually adjust the shade level; the helmet automatically switches to Shade 11 upon arc ignition and returns to Shade 4 DIN when the arc stops.
Headband Adjustment: The headband can be adjusted for a comfortable and secure fit. This involves pushing in a knob at the back of the headband and turning it until it clicks into position. The upper adjusting strap can also be set as low as possible for optimal fit.
Helmet Angle Adjustment: An eccentric knob allows the user to adjust the angle of the helmet relative to their face, ensuring a comfortable viewing position.
Distance from Eyes Adjustment: Locking-nuts on both sides of the helmet allow for adjustment of the distance from the eyes to the shade cartridge. It's important to adjust both sides simultaneously to ensure the helmet remains straight and to prevent uneven darkening due to varying distances.
Magnifying Lens Compatibility: The helmet is designed to accommodate magnifying lenses (diopters +0, +1.5, +2.0, +2.5), which can be inserted to assist welders with vision impairments or those requiring enhanced detail for their work.
Solar Powered: The helmet is powered by solar cells, eliminating the need for battery replacement and ensuring continuous operation as long as there is sufficient light exposure.
Lightweight Design: Weighing only 16.6 oz (470 grams), the helmet is designed for extended wear without causing undue strain on the user's neck and head.
High Impact Material: The helmet's construction from high-impact synthetic material provides durability and protection against physical impacts in the welding environment.

Maintenance Features:

Proper maintenance is crucial for ensuring the longevity, effectiveness, and safety of the Eye-Tech 11 Mono Welding Helmet.

Protective Plate Replacement: Pitted or scratched external and internal protective plates can impair vision and reduce protection. These should be replaced immediately when worn or damaged. It is critical to always keep both protective plates in place to prevent welding spatter from damaging the shade cartridge, which can void the warranty and compromise UV/IR protection.
Cleaning:
- Solar Cells: The solar cells should be kept clean. They can be wiped with a damp, not wet, cloth dipped in soapy water, and then dried with a soft, clean cloth.
- Cover Lenses: If the front or rear cover lens becomes dirty or damaged, it should be cleaned or replaced.
- General Cleaning: Abrasive cleaning agents should not be used on any part of the helmet.
Shade Cartridge Replacement: The shade cartridge can be replaced by pushing it outwards from the upper inside rim of the helmet. Reinstallation is the reverse process. The shade cartridge itself should not be opened.
Sweatband Maintenance: The sweatband, designed for the forehead, is removable and washable, allowing for hygienic maintenance.
Storage: The helmet, especially the shade cartridge, should be kept dry and not placed on hot surfaces.
Troubleshooting:
- Uneven Darkening: If uneven darkening occurs, ensure the helmet is worn straight and, if necessary, decrease the distance between the eyes and the shade cartridge.
- No Darkening/Flickering: If the shade cartridge does not darken or flickers, check for dirty sensors or a dirty/damaged front cover lens. Also, ensure the welding current is not too low.
- Slow Switching Times: This can be caused by low temperatures (below 14°F) or insufficient lighting.
- Poor Visibility: Verify that shade levels are not set incorrectly, clean dirty front or rear cover lenses, and ensure sufficient room lighting.
- Helmet Slipping: Adjust the headband properly if the helmet slips.
Safety Precautions:
- Never attempt to open the shade cartridge.
- Do not use the helmet in cold weather (below 14°F).
- Avoid dropping, striking, or bending the helmet.
- Always ensure adequate ventilation or use breathing devices to protect against welding fumes and gases.
- If faults cannot be corrected through troubleshooting, the helmet should not be used, and the distributor should be contacted for assistance.

The Eye-Tech 11 Mono Welding Helmet is a robust and user-friendly tool designed to enhance safety and efficiency for welders, provided it is used and maintained according to these instructions.
