Choosing the right auto darkening welding helmet is curial since your protection and quality of welding job depends on it. Here are some tips that can help you choose the right one:
Auto darkening helmets come in a range of shades. You can find within set ranges 6 to 9 or 9 to 13. Go for the shade that is compatible with the type of welding you ought to perform.
Auto darkening welding helmets feature up to 4 arc sensors. More sensors offer a better response, sensitivity and reliability in a low amp or obstructed applications.
Switching speed indicates the amount of time a lens takes to become light to dark as the arc is truck. If the switching speed of your auto darkening welding helmet is fast, it will cause less fatigue to your eyeballs. Initially, when the auto darkening helmets were introduced, they had a switching speed of 1/3,600 of a second. Now, you can find them between 1/10,000 and 1/25,000 of a second.
Auto darkening welding helmets are powered with either replaceable lithium batteries or they use a combination of solar cells with replaceable lithium batteries. It all comes down to personal preferences when it comes to choosing either one. The welding helmets that are powered by replaceable batteries offer a potential for a longer service life than the ones that are powered with non-replaceable batteries as they have a service life of 5 to 7 years. The helmets that are a combination of solar power and batteries make a pretty good choice. Regardless of the model you choose, it is advised to always have replacement batteries at hand.
Your auto-darkening welding helmet should have a comfortable fit. Make sure the headgear adjusts up, down, forward and backward. Wear the helmet to see if it is up to the kind of comfort you desire. Also check the balance of the helmet as the ones with poor balance can cause neck strain and fatigue over the course of your work shift.
This typically depends on personal preferences and how much out-of-position welding are you likely to performance. Usually, the viewing sizes range from 6 square inch for light duty applications and 9 square inch for industrial use.
Adjustable Sensitivity control
The sensitivity control of your welding helmet should be adjustable. Sensitivity control means how much light will trigger the lens to become dark. This function is useful when you are dealing with low amperage tasks like TIG.
Adjustable delay control
This is another feature that you will find useful in your welding helmet. It lets you set how long the lens is going to stay dark after the welding arc stops. When you are dealing with large welding products, having a short delay will be handy as you will be able to reposition for the next weld in a short time. A longer delay time, on the other hand, is going to be helpful when you are welding at high amperages as the molten metal might still be emitting harmful rays.
