Please read this manual carefully before using this product.

The auto-darkening helmet with improved High Definition Filter Optics, delivers a new generation of face and eye protection. Advanced integrated

technology, such as LCD, optoelectronics detection, solar power, and microelectronics are coordinated to produce one of the safest, fastest and most

reliable auto-darkening helmets available. The auto-darkening helmet not only can efficiently protect operator’s eyes and face from sparks, spatter, and

harmful radiation under normal welding conditions, but also can make both hands free and strike arc accurately resulting in increased efficiency

and improved quality welds. It may be widely used for various welding, cutting, spraying and arc gouging, etc.

INTRO

DUCTION

This auto-darkening helmet is not suitable for "overhead" welding, laser welding/cutting, or oxyacetylene welding/cutting applications. This helmet will not protect against

explosive devices or corrosive liquids. Machine guards or eye splash protection must be used when these hazards are present. Impact resistant, primary eye protection, spectacles

or goggles that meet current ANSI specifications must be worn at all times when using this welding helmet. Avoid 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.

Do not make any modifications to either the ADF cartridge or helmet, other than those specified in this manual.

Do not use any replacement parts other than those specified in this manual. Unauthorized modifications and replacement parts

will void the warranty and expose the user to the risk of personal injury.

Do not immerse this helmet in water because this model is not waterproof.

Do not use any solvents on any ADF or helmet components.

The recommended operating temperature range for this ADF cartridge is -10°C~65°C (14°F~149°F). Do not use this device beyond these temperature limits. Failure to follow these

warnings and/or failure to follow all of the operating instructions could result in severe personal injury.

WARN

INGS

BEFORE USE

-Check for light tightness and check the inside & outside protection lens are clean and that no dirt is covering the sensors on the front of the

au to-darkening-filter (ADF) cartridge. Make sure the protection films on both inside & outside protection lens are removed.

- Inspect all operating parts for signs of wear or damage. Any scratched, cracked, or pitted parts should be replaced immediately.

-When the back light of the display screen is not on, first press any button to activate the screen with light, then

press the button SHADE, DELAY, or SENSITIVITY for selection. If the filter is in the GRIND mode, first press the GRIND button to activate the screen,

then press again to change to WELD mode.

VARIABLE SHADE CONTROL

If the Shade is in the range of 5~9, press WELD/GRIND button repeatedly until both icon 2 and icon 4 appear on the screen (SEE FIG.1). Then press SHADE button

repeatedly until the desired Shade shown in Icon 8.

If the Shade is in the range of 9~13, press WELD/GRIND button repeatedly until both icon 2 and icon 5 appear on the screen. Then press SHADE button

repeatedly until the desired Shade shown in Icon 8.

Note: Choose an optimum Shade number for the required welding process or application (see Table 1).

If this ADF does not darken when striking arc, stop welding immediately and contact our representative.

OPERATION

INSTRU

CTION

SENSITIVITY CONTROL

- The responsive to different light levels in various welding processes can be adjusted in the range 1-5(from low to high).

Press the SENSITIVITY button twice to start the setting. The Icon 6 on the screen flashes (from 1 to 5). Repeatedly press the SENSITIVITY button until

the desired level shown in Icon 6.

Turn to 1 (low) : The photosensitivity changes to be lower.

Suitable for high amperage welding and welding in bright light conditions (lamp light or sun light).

Turn to 5 (high) : The photosensitivity changes to be higher.

Suitable for low amperage welding and using in poor light conditions.

Suitable for using with steady arc process such as TIG welding.

Under normal use, a higher sensitivity setting is recommended.

DELAY CONTROL

The length of time delay for the ADF returns to light state after welding can be adjusted in the range 1-5 (for 0.1~0.9s). The time delay is for

protection of welder’s eyes from strong residual rays after welding.

Press the DELAY button twice to start the setting. The Icon 7 on the screen flashes (from 1 to 5). Repeatedly press the DELAY button until the

desired length of time delay shown in Icon 7.

Turn to 1 (0.1s) : The time the ADF lighten after welding to be shorter. The shortest time is about 0.1s depending upon welding point temperature and

shade set. This setting is ideal for track welding or production welding with short welds.

Turn to 5 (0.9s) : The time the ADF lighten after welding to be longer. The longest time is about 0.9s depending upon welding point temperature and shade

set. This setting is ideal for welding at high amperage where there is an after glow from the weld.

GRIND SELECTION

Press WELD/GRIND button repeatedly until icon 3 appears on the screen and the red light beside the button flashes. Additionally, icon 8 will show shade 4.

Note:Do not weld in the Grind mode, the ADF will not darken.

JOB SETTING

3 most frequently used setting can be stored and reactivated easily by using the 3 JOB buttons (12) on the right side of the screen.

Upon use of this helmet, the last ADF settings will be stored automatically (stored about 5 minutes after). The next time when you start to weld, the last settings

will be automatically re-activated. If you want to store a completed welding setting, press and hold one of the JOB buttons and stop pressing when the icon 9 stops

flashing. To activate the stored memory, press the JOB button.

Note: only in welding status you can activate the memory. Change to welding if you are currently using the grinding function.

HEADGEAR ADJUSTMENTS

Because the shapes of man's heads vary from person to person. The work positions and the observing angles are different. Operator may adjust the headband in 5 parameters:

Select eye level by Headband adjusting buttons (25).

Select view angle by Segmental positioning plate (24).

Adjust head size perimeter by pushing and turning the Headband tightness adjusting knob (19).

Select eyes distance from ADF by adjusting Headgear screws to 1 of the 5 slots on the Headgear slider (18). Make sure both sides are equally positioned for proper vision.

Select the height of the headgear by adjusting the Block washers(17,23) up or down on the Block washer adjustment(21).

POWER SUPPLY AND REPLACE THE BATTERY

The power of the auto-darkening helmet is provided by solar cells and 1pcs of CR2450 lithium battery.

When change the battery, open the Battery holder (8) at the side of the ADF and replace the battery (9).

BATTERY INDICATOR

Icon 1 indicates the battery status. Replace the battery when it is low, otherwise, the ADF switching time will become slower and shade accuracy will be

compromised.

REAL VISION TECHNOLOGY

Altavista HD is a Real Vision welding helmet. With advanced Real Vision Technology, the users can weld with improved clarity due to new complex coating

technology, grind with precision while in grind mode and finally see the job performance in the light state in the full spectrum of colors. There is no

need to remove the helmet to see clearly! Results are enhanced the weld quality, increased efficiency and improved safety because the users can see more.

ADF SAVING MODE

Altavista HD has Auto-on and Auto-off function and helps saving power consumption and extending the life of the ADF. When the ambient light is less than 3

Lux switches off automatically while when the ambient light is above 10 Lux ADF switches on automatically and gets into stand-by mode. We recommend storing

the helmet in the special bag once the work session has been completed in order to extend the life of the battery and of the filter.

EXTRA HEAT STABILITY

This function blocks the ADF in dark state when the working temperature hits the limit of 120°C. Considering that Altavista HD works with stability and with

unchanged performance until 100°C, EXTRA HEAT STABILITY guarantees the safety of the welder even in very severe conditions.
