How To Test Auto Darkening Welding Helmets?
Welding comes with lots of hazards and messes. Arcs, sparks, fumes, UV rays, and even radiation; there are all different types of things emit from the welding spot. Hence, the person in charge of the welding process is at great risk without taking enough protection measurements.This is how it looks using a shade lens while welding:
Shade lenses or auto-darkening helmets are protective gear used for shielding your head and eyes against all those things. After buying a new auto-darkening helmet, one should check whether it is working or not. Remember that it is something that protects you from threatening lights. So, you should test it. Go through the complete article to know about some testing methods.
How Do Auto Darkening Helmets work?
They work automatically, which means that their darkening level automatically shifts up and down, sensing the brightness. However, many of them also allow you to set the darkening level manually. Meanwhile, there is a grind mode that comes with some of them. This special feature allows you to keep grinding anything without the light triggering your shade lens sensors.

What is the DIN number?
DIN is a standard that indicates the level of darkened your helmet is. Most shade lenses allow you to set the DIN between 3 and 14. If you increase the DIN level, it will be darker. Level 3 DIN allows 14% light when level 4 let 5% light inside. For different welding, you may need different levels of DIN.
The chart below has some recommended DIN number for various welding types:
How to Test Your Auto Darkening Shade Lens?
Below we shall go through some of the processes to test a darkening lens. Some of them are easy, while some should only be done when you are almost sure that the helmet will work. Let’s get into them-
Turn off the Grind Mode
Remember that the grind mode feature is for the purpose of disabling the auto-darkening feature. So, if it is turned on, the helmet will not get triggered by the lights. So, make sure that is it off.
Remote Control Method
Along with many different types of lights, the shade lens also gets triggered by IR. Your TV remote control also sends out IR signals. So, it is possible to use that to test the helmet.
Striking Arc Method
This one is a bit risky and should be done carefully.
Cigarette Lighter Method
If you are a smoker and have a cigarette lighter, then you can go for this method.
Torch Striker Method
If you have an oxy-acetylene lighter, you probably have a torch striker for it too.
Sunlight contains IR or UV rays. So, you can use that too.
There are two ways to test your shade lens battery.
Before you start testing your helmet, you must test its parts, especially if it is old or used for a while. You should test the batteries, shade, and sensor to be sure that they are not damaged. After using the helmet in a factory, clean it using a clean cloth to remove any dust that may be on it.
