TROOPER AUTO-DARKENING WELDING HELMET

SPECIFICATIONS

INTRODUCTION

The filter cartridge in the Variable Shade Auto-Darkening Welding Helmet is designed for arc welding or cutting applications, including hand welding, gas- protected welding,  argon arc welding, and plasma cutting.
The solar auto-darkening filter employs photoelectric sensors that cause the liquid crystal to change from a bright state to a dark state as soon as it receives arc light. The state changes from dark to bright shortly after the welding is finished. The delay is to protect the eyes and face from harmful infrared or ultraviolet radiation.

PERSONAL SAFETY
WARNING! Wear personal protective equipment approved by the Canadian Standards Association (CSA) or American National Standards Institute (ANSI).
PERSONAL PROTECTIVE EQUIPMENT

1. Always wear impact safety goggles that provide front and side protection for the eyes. Eye protection equipment should comply with CSA Z94.3-07 or ANSI Z87.1  standards based on the type of work performed.
2. Wear the appropriate type of full-face shield in addition to safety goggles, as the work can create glare or infrared/ ultraviolet light.
3. Non-skid footwear is recommended to maintain footing and balance in the work environment.

PERSONAL PRECAUTIONS
Control the tool, personal movement, and the work environment to avoid personal injury or damage to the tool.

1. Do not operate any tool when tired or under the influence of drugs, alcohol, or medications.
2. Avoid wearing clothes or jewelry that can become entangled with the moving parts of a tool. Keep long hair covered or bound.

SPECIFIC SAFETY PRECAUTIONS

WARNING! DO NOT let comfort or familiarity with the product (gained from repeated use) replace strict adherence to the tool safety rules. If you use this tool unsafely or incorrectly, you can suffer serious personal injury.
WARNING! The Auto-Darkening Welding Helmet does not protect against severe impact hazards, explosions, or corrosive liquids. Machine guards or eye splash protection must be used when these hazards are present.
WARNING! Using filter forms from any other manufacturer’s helmet can seriously impair the protection provided and may result in serious personal injury.

1. Use the correct tool for the job. This tool was designed for a specific function. Do not modify or alter this tool or use it for an unintended purpose.
2. This auto-darkening welding helmet is not recommended for overhead welding applications, laser welding, or laser cutting applications.
3. In the event of electronic failure, the filter remains dark to protect against UV and IR radiation.
4. The auto-darkening welding filter should always be used with the original outer cover lens. Never open or tamper with the filter cartridge.
5. Ensure the front cover lens is mounted before use and remove the protective film.
6. Ensure that the lens is clean and there is no dirt or spatter covering the 4 sensors at the front of the filter cartridge.
7. Inspect all parts for signs of wear or damage. Any scratched or cracked parts should be replaced prior to use.
8. Never place the helmet on a hot surface.
9. Arc rays can burn both eyes and skin. Arc welding produces intense visible and invisible (ultraviolet and infrared) rays. Wear a welding helmet fitted with the proper shade to protect your face and eyes when welding or watching.
10. Check whether welding or grinding mode is chosen before use.
11. The reaction of the Filter’s liquid crystal will be slower if the ambient temperature is low, but it will not affect protective functions.

UNPACKING

ASSEMBLY & INSTALLATION

Letter references in parenthesis (A) refer to the included Identification Key. Dashed numbers in parenthesis (Fig. 1-1) refer to a specific point in an illustration or image.

ADJUSTING THE FIT
The headband should be adjusted both in diameter and height.
The angle between face and helmet should also be adjusted (recommended 10° to 12°).

1. Adjust the headband diameter with the twist knob on the back (Fig. 1-1). The knob is locked until pushed in. Once unlocked, twist clockwise to tighten and counterclockwise to loosen.
2. Adjust the height by releasing the tab and changing the top strap hole (Fig. 1-2).
3. Adjust the helmet to get the desired viewing angle. Loosen the knobs (Fig. 1-3) and adjust the viewing angle when the helmet is down. Once the angle is correct, tighten the knobs until snug. The helmet should still swing up, but it should not drift downward when in place for welding.
4. To adjust the distance between the user’s face and ADF, loosen the knobs on both sides of the helmet (Fig. 1-4) until the headband can move back and forth freely,  deposition the headband at one of the 3 slots as desired. This should be done one side at a time and both sides should be located at the same position for proper auto-darkening filter operation.

OPERATION

BEFORE WELDING

1. Ensure that the internal and external protective films are removed from the lenses.
2. Check that the batteries have sufficient power to operate the helmet. When the battery power is low, the battery low volume indicator LED (Q) will glow red. The filter cartridge lens may not work correctly. Replace the batteries (see Maintenance – Battery Replacement).
3. Check that the arc sensors are clean and not blocked by dust or debris.
4. Check for headband tightness before each use.

SHADE NUMBER SELECTION
Manually set the shade range between 5 to 8 or 9 to 13 with the shade switch (S). Further, adjust the Shade Number with the control knob (J). Adjust the welding helmet’s Shade  Number to match the type of welding. Consult the Welding Shade Guide to determine the minimum shade for the amperage and welding method being employed.

DELAY TIME
Delay time refers to the time the cartridge filter is set to change from the dark to the bright state after welding stops. The delay can be adjusted (R) from 0.1 seconds up to a one-second delay.
SENSITIVITY
The sensitivity control (T) is set according to the welding process and ambient light.

1. Low Setting – suitable for high amperage welding and welding in areas with high levels of natural sunlight.
2. Medium Setting – suitable for most indoors and outdoors welding.
3. High Setting – suitable for low amperage welding and welding in areas with low light conditions, especially for low amperage argon-arc welding.

SELF-TEST

1. Press the TEST button (P) to see if it switches to the dark state.
2. Release the Test button to check that the filter returns to the bright state.

GRINDING MODE
The welding helmet can also be used to protect the face during grinding. Switching to Grind mode (Fig. 2) will prevent the filter cartridge from darkening when bright sparks are created.

CARE & MAINTENANCE

1. Maintain the tool with care. A tool in good condition is efficient, easier to control, and will have fewer problems.
2. Inspect the tool components periodically. Repair or replace damaged or worn components. Only use identical replacement parts when servicing.

WARNING! Only qualified service personnel should repair the tool. An improperly repaired tool may present a hazard to the user and/or others.

CHANGE EXTERNAL AND INTERNAL LENS
The external and internal lenses will wear out and need replacement after a period of use due to exposure to the heat, fumes, and particulate matter generated during welding.

1. Remove the filter cartridge by pressing the two lock switches at the bottom of the retaining frame inwards. Pull the retaining frame free from the welding helmet.

2. Remove the inner lens by pulling it from the top recess.
   2.1 The new inner cover lens is installed after the protective film is removed. Insert the lens’ leading edge under the tab on one side of the cartridge. Bend the lens in the middle and slide the other side under the other tab and push it into place.

3. Remove the external lens by pushing it out of the welding helmet.
   3.1 Pull the lens free of the rubber gasket.
   3.2 Remove the protective film from the new cover lens and slip it into the gasket.
   3.3 Insert the external lens back into the mask.

BATTERY REPLACEMENT

1. Rotate the battery cover plate (U) clockwise to remove.
2. Remove the old CR 2032 lithium battery and replace it with the new battery.
3. Replace the cover and rotate counterclockwise to secure the battery.

CLEANING
NOTICE! Do not use alcohol, gasoline, or diluents to clean the filter cartridge. Do not put place the filter cartridge into the water as this will damage the filter.
Clean the lens, helmet shell, and headband with a soft cotton cloth and mild soap. Replace the headband when required.
