There is a large range of welding helmets available in the market, such as a passive or auto-darkening lens, fixed or variable shade, two, three or four sensors and viewing size. Take the time and find the right helmet for your needs, it can increase your productivity, weld quality and comfort.
The helmet you choose should meet the Country’s Standards.This ensures that the helmet and lens has passed independent testing and can survive high impact from flying objects, provide 100% ultraviolet and infrared filtering regardless of shade setting, and meet advertised switching speeds and darkness shades in temperatures as low as -5 degrees and high as 55 degrees.
Passive vs. Auto-Darkening Lens
Welding lens shade numbers refer to the lens’ ability to filter light. All auto-darkening welding helmets provide 100% protection against harmful infrared and UV rays and may range from a #8 shade for low-amp applications up to a #13 shade for high-amp applications.
A passive lens helmet uses UV- and IR-coated dark-tinted glass with a fixed shade value, usually #10. This helmet is worn in the up position while the electrode, gun or torch is positioned. With a quick nod or snap of the neck, the operator flips the helmet into position immediately before striking an arc.
Passive lens helmets provide an economical choice; however, they have some cons:
An auto-darkening lens addresses the above issues. When inactive, an auto-darkening lens usually has a #3 or #4 shade, which is relatively easy to see through. When the sensors on the helmet sense an arc start, the lens automatically darkens, in a fraction of a second (typically 1/12,000 to 1/20,000 of a second for industrial-grade helmets), to shade #8 to #13.
Because the helmet stays in position before, during, and after the weld, an auto-darkening welding helmet allows you to set up your welding joint with the hood in position. No more head snaps to lower the helmet. No more sloppy starts because the torch moved. No more raising and lowering the helmet for tack welds. Auto-Darkening helmets can improve weld quality, and can ease neck strain associated with snapping the helmet into place.
Auto-Darkening Options
Auto-darkening helmets are available for every welding level, and a range of applications – light industrial to heavy industrial. If you’re looking for an auto-darkening helmet there are some things to consider:
Other Helmet Considerations
A lighter weight helmet minimizes strain on the user’s neck reducing fatigue and increasing comfort. The more you weld, the more you and your neck will appreciate a helmet that weighs less.
Finally, the latest auto-darkening helmets usually provide benefits specifically for the industrial welder: an aluminium heat shield to protect the lens from high heat (300+ amps) applications, silver colouring to reflect the heat away from the wearer, gaskets for shock absorption and increased longevity and commonality of parts to decrease inventory requirements for larger organisations.
If welding is, or is part of your career, take the time to find the helmet that’s right for you. While it may be tempting to buy the least expensive helmet, take the time to explore all options, it can have long-term benefits for your comfort and safety.
