• IF some problem is shown in any part of the product, for example, the air supply is stopped

or its amount is decreased;

• IF it gets hard to breathe, feeling dizzy or headache, feeling the smell or taste of the contaminants and its stimulus occurred;

• NEVER use in place with too high level of contamination. If you suspect the levels reach a level which this respirator may no longer provide enough protection.

WARNING

Never remove the respirator in areas where the air is contaminated. Always take off the PAPR after you step out of the workplace.

Respirator removal

Always exit the contaminated area immediately if any of the following conditions occur:

Airflow rate test Take airflow test always before using this product.

Make sure all the components are fully assembled before testing. Connect the end of hose to the bottom of airflow indicator and then start the Button. Keep the Flow Indicator vertical.(see fig.12) If the ball inside the pipe floating above the limited line in low speed mode, it proves normal function. If the ball cannot float up to limited line, please refer to Trouble-shooting Guide on page11.

MAINTENANCE

The respirator components must be cleaned, inspected and prepared for next use after each use. Use soft cloth dipped in mild soap water for wiping. Be careful for the water NOT to get inside the body.

CLEANING

The face seal can be used to facilitate cleaning after disassembling from the shell, but it must be replaced if it is damaged.

Blower unit and battery pack: Clean the outer surfaces of the PAPR and battery pack with a soft cloth dampened in a solution of water and mild, pH neutral detergent. Be careful for the water NOT to get inside the body. Do not use solvents or abrasive cleaners. Ensure the electrical contacts of the motor/blower and battery pack are dry before assembling well. Breathing tube: Wiping the exterior is insufficient. Clean the outer hose and connection on the breathing tube with the soft cloth dipped in water and detergent solution. Optional breathing tube covers can also be used to facilitate cleaning. Ensure the breathing tube is completely dry before using or storing. They cannot be immersed in liquids for cleaning and must be replaced if wet. Filter: Open the filter cover and inspect all the filters and spark screens. The Particle,

gas and pre-filters cannot be cleaned. The spark screen can be cleaned using a clean,

soft cloth dipped in a solution of water and a mild pH neutral detergent. Completely dry the spark screen with a clean cloth. Replace the pre-filter and Particle filter if excessively dirty, wet or damaged. Do not attempt to remove contamination using a compressed air line as this will automatically invalidate the warranty. If the spark screen cannot be cleaned or is damaged, replace with a new spark screen.

WELDING HELMET OPERATING INSTRUCTION

WARNING

Auto-Darkening welding helmets are designed to protect the eye and face from sparks, spatter and harmful radiation under normal welding conditions. This auto darkening filter will

automatically turn on when pick it up. The filter automatically changes from a light state to a dark state when an arc is struck, and it returns to the light state when welding stops.

The Auto-Darkening welding helmet comes assembled. But before it can be used, it must be adjusted to fit the user properly. Check battery surfaces and contacts and

clean it if necessary. Verify if the battery is in good condition and installed properly.

Set up for delay time, sensitivity and shade number for your application.

The helmet should be stored in dry, cool and dark area and remove the battery, when not using it for a long time.

WARNING

The user must stop using the auto-darkening welding helmet immediately

if the above-mentioned problems cannot be corrected. Contact the dealer.

• Irregular Darkening Dimming

Headband has been set unevenly and there is an uneven distance from the eyes to the filter lens. (Reset the headband to reduce the difference to the filter).

• Auto-Darkening filter does not darken or flickers

① Front cover lens is soiled or damaged (Change the cover lens). ② Sensors are soiled (Clean the sensors surface). ③ Welding current is too low (Adjust the sensitivity level to higher). ④ Check battery and verify they are in good condition and installed properly. Also, check

battery surfaces and contacts and clean if necessary.

• Slow response

Operating temperature is too low (Do not use at temperatures below -5°C or 23°F).

• Poor vision

① Front/inside cover lens and/or the filter is soiled (Change lens). ② There is insufficient ambient light. ③ Shade number is incorrectly set (Reset the shade number). ④ Check if removing the film on the front cover lens.

• Welding helmet slips

Headband is not properly adjusted (Readjust the headband).

COMMON PROBLEMS AND REMEDIES

CARTRIDGE OPERATION

• BATTERY INSTALLATION

Slide the battery holder out of the auto darkening filter, (remove the used battery when replacing battery), put new CR2450 batteries inside the battery holder, and put the battery holder back into the auto darkening filter. Please make sure the anode and cathode of the battery are installed correctly (See fig.13).

• POWER ON / OFF

This auto darkening filter will automatically turn on when pick it up. Sensitivity level setting 0 - 9: The welding helmet will be automatically off after 15 minutes not being used. Sensitivity level setting =10: The filter will be darkening all the time to meet some specially welding application under both WELD MODE and CUTTING MODE. With this setting, the welding helmet will not automatically turn off after 15 minutes of not being used.

To save power, remember to set the sensitivity value between 0 - 9 and keep the filter in dark place when not being used.

• DIGITAL SCREEN ACTIVATION

Press any of four button to activate the digital screen (See fig.14a). After 6 seconds, digital screen will automatically turn to standby mode. Short press the button again will active the screen once more and previous settings will remain.

• MODE CONTROL

Short Press “ON / MODE” button to select the mode appropriate for the work activity (See fig.14a):

Weld Mode − used for most welding applications. Push “FUNC” button to adjust shade

number, sensitivity, and delay settings properly before welding. In this mode the lens turns to dark immediately when you start welding.

Cutting Mode − used for cutting applications. Push “FUNC” button to adjust shade number,

sensitivity, and delay settings properly before cutting. In this mode the lens turns to dark immediately when you start cutting.

Grind Mode − used for grinding applications. In this mode the lens shade is fixed shade No.

4. Can not adjust shade number, sensitivity, and delay settings.

• BATTERY INDICATOR The symbol “ ” show the current state of the battery (See fig.14b). The volume of batteries has four levels symbol to appear (See fig.14c). The symbol “ ” appears on the display screen before 1−2 days of battery life remains, the CR2450 lithium batteries should be replaced in time. The symbol of the Battery Indicator is not real-time, should be updated after pressing “ON / MODE” button shortly.

Be sure Positive (+) side of battery faces up.

fig.14a fig.14b fig.14c

fig.13

• VARIABLE SHADE CONTROL

After turn on the lens, short press “FUNC” button to choose “SHADE”, and adjust the lens shade number. Use “ ” and “ ” buttons to select the lens shade in the dark state. The shade range for each mode are as follows:

Cutting Mode − Shade 5 ~ 8 (See fig.15a) Weld Mode − Shade 9 ~ 13 (See fig.15b)

Grind Mode − No. 4 only (See fig.15c)

Select the proper shade number for your welding / cutting process, by referring to the “Shade Guide Table” on page 19.

• SENSITIVITY CONTROL Press “FUNC” button to choose “SENSITIVITY”. Use “ ” and “ ” buttons to make the lens more or less sensitive to arc light of different welding processes. Sensitivity setting 5-10 is the normal setting for everyday use. The sensitivity ranges for each mode are as follows:

Cutting Mode (Shade 5 ~ 8) / Weld Mode (Shade 9 ~ 13) − Sensitivity 0 ~ 10 (See fig.16a / 16b)

Grind Mode − No sensitivity adjustment

As a simple rule for optimum performance, it is recommended to set sensitivity to the maximum at the beginning and then gradually reduce it, until the filter reacts only to the welding light flash and without annoying spurious triggering due to ambient light conditions (direct sun, intensive artificial light, neighbouring welder's arcs etc.).

It may be necessary to adjust helmet sensitivity to accommodate different lighting conditions or if lens is flashing On and Off. Adjust helmet sensitivity as follows: Adjust helmet sensitivity in lighting conditions helmet will be used in.

• Press “ ” button to lower setting to 0.

• VARIABLE SHADE CONTROL

Cutting Mode − Shade 5 ~ 8 (See fig.15a) Weld Mode − Shade 9 ~ 13 (See fig.15b)

Grind Mode − No. 4 only (See fig.15c)

Select the proper shade number for your welding / cutting process, by referring to the “Shade Guide Table” on page 19.

Cutting Mode (Shade 5 ~ 8) / Weld Mode (Shade 9 ~ 13) − Sensitivity 0 ~ 10 (See fig.16a / 16b)

Grind Mode − No sensitivity adjustment

• Press “ ” button to lower setting to 0.

fig.15bfig.15a

fig.15c

fig.16a fig.16b

• Face the helmet in the direction of use, exposing it to the surrounding light conditions.

• Press “ ” button repeatedly until the lens darkens, then press “ ” button until lens clears.

Helmet is ready for use. Slight readjustment may be necessary for certain applications or if lens is flashing on and off.

• DELAY CONTROL

Press “FUNC” button to choose “DELAY”, begin lens delay adjustments. Use the Lens Delay Control “ ” and “ ” buttons to adjust the time for the lens to switch to the clear state after welding or cutting.

Cutting Mode (Shade 5 ~ 8) / Weld Mode (Shade 9 ~ 13) − Delay 0 ~ 10 (See fig.17a / 17b)

Grind Mode − No sensitivity adjustment

The delay is particularly useful in eliminating bright after-rays present in higher amperage applications where the molten puddle remains bright momentarily after welding. Use the Lens Delay Control buttons to adjust delay from 0 to 10 (0.1 to 1.0 second). When welding stopped, the viewing window automatically changes from dark back to light but with a pre-set delay to compensate for any bright afterglow on the workpiece. The delay time / response can be set from Level 0 to level 10. It is recommended to use a shorter delay with spot welding applications and a longer delay with applications using higher currents. Longer delays can also be used for low current TIG welding, and TIG / MIG / MAG pulse.

• ADJUSTING THE FIT OF THE HELMET

The overall circumference of the headband can be made larger or smaller by rotating the knob on the back of the headband (See adjustment “Y” in fig.18). This can be done while wearing the helmet and allows just the right tension to be set to keep the helmet firmly on the head without it being too tight.

• If the headband is riding too high or too low on your head, adjust the strap which passes over the top of your head. To do this release the end of the band by pushing the locking pin out of the hole in the band. Slide the two portions of the band to a greater or lesser width as required and push the locking pin through the nearest hole (See adjustment “W” in fig.18).

• Front and back bands will automatically self-adjust according to headform, and soft pads suit forehead and back of head perfectly, which will bring more comfort (See fig.19a). Test the fit of the headband by lifting up and closing down the helmet a few times while wearing it. If the headband moves while tilting, re-adjust it until it is stable.

• ADJUSTING THE DISTANCE BETWEEN THE HELMET AND THE FACE

Step 1: Press down and hold the “LOCK” latch on both sides (See fig.19b) and it can be slide back and forth. Step 2: Loosen the “LOCK” latch and keep it snap into slots. Please make sure the distance between the lens to both eyes are equal, to avoid uneven darkness.

• ADJUSTING VIEW ANGLE POSITION

Tilt adjustment is located on right side of helmet. Loosen the right headgear tension knob and adjust the lever forward or back to the proper position. Re-tighten the right headgear tension knob (See fig.19c).

SHADE GUIDE TABLE

(1)

As a rule of thumb, start with a shade that is too dark, then go to a lighter shade which gives sufﬁcient view of the weld zone without going below the minimum. In oxyfuel gas welding or cutting where the torch produces a high yellow light, it is desirable to use a ﬁlter lens that absorbs the yellow or sodium line the visible light of the (spectrum) operation

(2)

These values apply where the actual arc is clearly seen. Experience has shown that lighter ﬁlters may be used when the arc is hidden by the workp iece. Data from ANSI Z49.1-2005
