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.

• 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.

• 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).

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

 Front cover lens is soiled or damaged (Change the cover lens).

 Sensors are soiled (Clean the sensors surface).

 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

 Front/inside cover lens and/or the filter is soiled (Change lens).

 There is insufficient ambient light.

 Shade number is incorrectly set (Reset the shade number).

 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

• 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.

• 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).

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.

• 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.

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).

REPLACING THE SHELL COVER

Place 

fingertips

 into the gap around the shell cover and flex the shell cover upwards until it 

releases from the helmet (See fig.20a / 20b). When installing the new shell cover, put the 

side of lug boss of shell cover into the slot and then lock the other side into the helmet. When 

hearing “click”,the shell cover is completely fixed (See fig.20c).

REPLACING THE AUTO DARKENING FILTER

Press the thumb on the bottom sides of the auto darkening filter and push it upward

 (See 

fig.21a), remove the auto darkening filter from the shell (See fig.21b). When installing the 

new auto darkening filter, clip the lower part of the filter into the bottom of helmet window first, 

and then insert the whole filter into the helmet window (See fig.21c).

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
