Light in Weight...

As I have said a little time before, the Armour Guard Auto-Darkening Welding Lens is exceptionally lightweight despite being made of glass.

It weighs only 2.39 ounces.

Considerations:

Flashing Is Once More- A Problem...

As you know, in this world, nothing is free of defects, and Armour Guard Welding Lens is not free of this rule either.

The most significant problem of this lens is that it sometimes flashes before dimming.

It is best to do some research before you buy a 2x4 auto darkening welding lens to avoid spending your money in vain.

There are a few things you need to look out for and consider before buying one.

Viewing Area:

It is best if you choose a lens of a standard or larger size to ensure having a large viewing area.

After all, the quality of your weld defines the quality of your work, and the better you see, the better you will be able to weld.

Never forget, the quality, the efficiency and the speed of your welding are primarily dependent on your viewing capacity.

Clarity:

But don't just feel like buying whatever lens having a more extensive viewing capacity.

This is not the only thing your visibility depends on. 

The lens clarity plays a crucial part in determining how well you see while welding.

You should buy a lens having a clarity level of 3 on a scale of 1-3 after testing.

Fixed Or Variable Shade?

Most of the auto darkening welding lenses have a fixed shade of 10.

Such lenses offer the same level of protection despite the change in amps of the light from the welding.

So when you use the glass to weld different materials of various thicknesses, typically, you need to continue some precise movement to reduce eye strain.

As a result, you might feel tired fast.

Thus, for heavy-duty industrial welders, it is best to buy a lens having variable shade options.

But if you are mostly welding one kind of material with fixed thickness at a fixed amperage, then it is best to save your money and stick with a lens having a fixed shade 10.

Switching Speed:

The switching speed of an automatic lens is usually expressed in ratings of 1/3,600 per second to the highest of 1/25,000 per second.

The switching speed indicates the quickness of a lens’ transformation from its natural shade to darker shade after the beginning of welding.

If you are an entry-level welder, then do not bother buying a lens having higher level switching speed and just save your money.

But if you are a professional, then it is best to buy a lens having an intermediate or expert level switching speed and protect yourself from suffering from eye fatigue.

Power Source:

2 x 4 auto darkening lenses comes with various power options.

Some lenses have replaceable lithium or AAA barriers. And some lenses get powered from solar rays through solar panels.

While lithium batteries have extended battery life, they are comparatively costly and hard to find compared to AAA batteries.

You can skip the battery issue by choosing a lens having the sun as the power source.

Still, you should remember to periodically put it in direct sunlight to avoid the possibility of flashing.

It is best if you put such lenses into direct sunlight before each use.

Comfort:

And last but not least, you should buy a lens having as little weight as possible. 

Using a slightly heavier lens might feel nothing to you at the beginning, but later you will suffer from neck pain, trust me.

It is now time to say our goodbyes.

So, what do you think? Which lens is best suitable for you?

Remember, our eyes are invaluable. So do careful research and be mindful while choosing the best 2 x 4 auto darkening lens most appropriate for your use.

Have a cautious time welding!
