How to test Auto-dark welding helmet
                     TESTING OF AUTO-DARK
WELDING HELMET
Simple steps to test your 
auto-dark welding helmet  before 
purchasing are listed below
Use sunlight or a bright bulb
 Sunlight test is the easiest way to check 
almost all the features of the auto-
darkening helmet. Simply put-on helmet 
and look toward the sun in the afternoon 
and then follow these instructions step 
by step 
1. Test for damage sensors
 The auto-darkening helmet has 2 or 4 
independent arc sensor in the corners of 
view area. Cover all other sensors with 
fingers tip except the one which you 
want to check. Look toward the sun if 
the sensor works properly, then it turns 
the filter into the dark shade
2. Sensor response test
 Now move your hand in front of the view 
area.  Sunlight act as a spark light and 
lens shade become dark.  When your 
hand comes in front of sun then lens 
offer standard light shade. Now move 
your hand slowly so that lens takes its 
time for shade shifting
3. Sensitivity and delay control 
test
 Light to dark shade shifting speed 
(sensitivity) must be very fast, more than 
0.0004 seconds. Make sensitivity 
adjustment in such a way that lens should 
be able to respond with the change in light. 
 And dark to light shade shifting speed 
(delay time) can be within 0.1-1 sec.  Delay 
time prevent you from being flashed when 
blockage of sensors occur for a moment
4. View area clarity test
 You can see clearly everything in 
standard light shade with screech lens. 
But you are not able to see properly 
when spark ignite and dark shade 
become active. At this time you should 
consider to change the lens or purchase 
a new helmet.
5. Shade adjustment test
 The auto-darkening helmet has an 
adjustable knob or digital control for 
shade control. Look at the sun and 
change shade step by step from 9 to 13 
as you move from 9 to 13, the shade 
darkness increase. Fix that shade which 
can give you proper eye protection as 
well as you are also able to see weld 
puddle.
6. Grind mode testing
 If your helmet has separate grinding 
mode than switch it ON. If auto-
darkening sensors are still working then 
grinding mode doesn't working. Auto-
darkening shade lens work only when 
grinding mode is switch-off.  Make sure 
grinding mode is switch-off before start 
welding. 
7. Test for UV and IR rays
 Put your helmet. Look at the TV remote 
light diode and press any button.  As 
long as you press the button, your lens 
should be in dark shade. If nothing 
happens, change the sensitivity of your 
helmet. If it's also not working then think 
about changing of the helmet.
