What Shade Lens For MIG Welding – Guide For Selecting The Right One
Many industrial level projects require proper protection to ensure the safety of the worker. Welding is not an exception. The shade lenses (also known as auto-darkening helmets) are a prime example among many protective gear. To remove the vulnerability of your eyes from the arcs and radiation, these helmets have darkened shades.
For good versatility, you need a shade lens that lets you adjust the darkening level within DIN5 to DIN14. The bigger that number, the darker the lens becomes. There are various other factors you must research while getting the right shade lens for MIG welding. But instead of turning this article into a complete buying guide, we will also fill you in with other necessary knowledge.
Pros of Using a shade Lens
Aside from blocking bright arcs and protecting your eyes, the shade lens also has some other advantages. They are given below-
If you are confused about the DIN number of a welding helmet, it means the level of darkened a helmet is. You must need a darkened lens for MIG or FCAW welding. In case you have less idea on these welding methods, then we should say a thing or two about them.
While the welding process is going on, the more amp it needs, the brighter the arc gets. So, you also need a higher DIN level. In this regard, OSHA, AWS, and ANSI have given some standard DIN levels.
Check out this table below containing the safe DIN level for different amp draws by OSHA, ANSI, and AWS.
OSHA DIN Number
AWS & ANSI DIN Num
60 to 160A
160 to 250A
250 to 500A
As you can see, AWS and ANSI were more cautious about this. Hence, they set a higher DIN level for every amp range than the OSHA.
Remember that, in case you work in a darker place, you should take a shade lens with a base DIN of 3 to 3.5. Otherwise, you may need to open the helmet while not welding. Different DIN level allows a different percentage of light to go through the shade lens. DIN 3 allows only 5% light, while DIN 13 allows 0.00072%.
You should adjust your DIN based on the welding process too. The chart below shows the recommended DIN for different types of welding-
The Adjustment of Shade Lens
You can adjust the shade lens with ease using the knob or dial that the helmet comes with. While setting the suitable darkening level, you should keep some factors in mind.
How to Check the Shade Lens Capabilities?
After getting a shade lens, check if it can provide the level of protection it promises. The process of checking that is easier than you might think. The shade lens sensor gets triggered by many things, including arcs and IR rays emitted from the welding.
Do you know what else emits infrared rays? Yes, a TV remote control. See if the infrared ray from the remote can trigger the helmet from every angle and position. Pretty easy, right?
Some Other Factors
Aside from everything that we have talked about so far, there are also some other points. To gain the perfect shade lens for your MIG welding, see if it-
You cannot deny the necessitates of all the equipment that you can get for complete protection during the welding process. Having good knowledge of all of them will let you buy the perfect items. With the proper darkening helmet, you can perform your MIG welding without any health issues.
