1. TROUBLESHOOTING

Some common problems listed below, together with their possible solutions, can

arise when using the helmet:

Problem:The filter does not darken or is unstable when switching from light to dark and viceversa

Possible Cause:                                                         

The external transparent protection of the filter is dirty or damaged 

The sensors are dirty

The level of the welding current level(sensitivity)is too low

The batteries are not in good condition or not properly inserted

 Battery terminals and the contact surfaces of the filter are dirtyor oxidized

The switch "WELD-GRIND"on the filter is in position "GRIND"

Solution:

Change the exernal transparent

Clean the sensor surface

Increase sensitivity

Replace the batteries or remove them and re-insert them properly

Clean both

Place the

Switch in the "WELD"

Problem:Slow switching

Possible Cause:

The operating temperature is too low

Solution:

Do not use at temperatures under -5℃(+23℉)

Problem:Poor visibility

Possible Cause:

The external or/and internal prtection of the filter is/are dirty or damaged

Not enough light in thesyrrounding area

The scale number is not set correctly,or the fixed scale number is not suitable

 Solution:

Clean the dirty components and replace the damaged ones    

Where possible,select the correct number

Problem:Filter darkening without arc being struck 

Possible Cause:

Sensitivity is too high

Solution:

Adjust sensitivity to the right level

Problem:Filter remains dark after completing a weld

Possible Cause:

Delay set too high

Ambient light is too bright

Solution:

Adjust delay

Reduce light level

Problem:Weld spatter is damaging the filter

Possible Cause:

Missed,damaged,broken,distorted front cover

Solution:

Replace front cover lens

2. What does 1 / 1 / 1 / 1 mean?

The main parameters of welding filters: optical class, light diffusion, light homogeneity and angle dependence. The parameters in each position can be any value from 1 (Class 1 is the best) to 3 (worst) and determine the characteristics of the filter.

1 / X / X / X : Optical class - Optical class indicates optical quality of the ocular.

X / 1 / X / X : Light diffusion - Light diffusion class (adjustable filters only )1, 2 or 3 indicates light diffusion class of the filter lens.

X / X / 1 / X : Light homogeneity - Variations in luminous transmittance class 1, 2 or 3 indicates shade variability in the dark state of the filter.

X / X / X / 1 : Angle dependence - Angle dependence of luminous transmittance class 1, 2 or 3 indicates the shade remains consistent when looking at an angle.

OPTICAL PERFORMANCE DEMONSTRATION Each optical data has 1-3 level , "1" means best level , "3" means worst level.

3. What does TURE COLOR mean?

TURE COLOR technology for the welding filter: With TURE COLOR technology, the images welders see through the welding filter will be more natural, and less distorted in color. And it will also be safer for them as they could see the red light from an alertor. 

5. Should I choose a fixed or variable shade?

If you are always using the same arc welding process on the same material, a fixed shade is sufficient. But if - like most welders - you are welding using a variety of processes, amperages or materials, your best bet is a variable shade helmet, which can be adjusted to the correct shade level for your particular need. For instance, when you are GTAW (TIG) welding at lower amperages, you may need to lighten up the lens to see what you are doing. A variable shade will permit this while a fixed shade will not.
