- 1). Select a helmet that offers a minimum rating of #4 shade for ultraviolet and infrared lighting. Anything less than this rating offers insufficient light filtering, which could result in damage to your eyes.
- 2). Inspect the packaging to determine the rate of darkening for the helmet. Entry-level helmets darken at a rate of 1/3,600th of a second. The faster the reaction time, the less fatigue your eyes will experience after a full day of welding.
- 3). Purchase a battery-operated helmet over a solar-powered unit. Battery-operated units last longer and when the battery wears out, you can replace it. When the solar battery wears out, the helmet no longer works, as the battery is non-replaceable.
- 4). Look for a helmet with an adjustable head strap so you can adjust the helmet to fit comfortably on your head. Non-adjustable helmets usually slip around or cause headaches because they fit too tight.
- 5). Choose a helmet that offers all of the necessary features but that weighs the least amount. The difference between a 1-lb. helmet compared to a 2-lb. helmet sounds minimal but over a full day, that extra pound can cause a lot of fatigue to your neck.
