A welding helmet is a kind of headgear that is used by a welder while performing welding tasks. It protects the wearer’s eyes, face, and neck from heat, sparks, flash burn, UV light and infrared light that can cause extreme damage. Thus, it is very important for professionals and welding hobbyists alike. There are many types of welding helmets on the market. That is why it can be confusing to decide which one to buy. Well, no need to worry. Below we give the comparison between standard or passive helmet and auto-darkening helmet.
Standard welding helmet
These helmets have been very popular. They are widely used from the very beginning. The user has to wear the helmet in the up position while positioning the electrode, gun or torch. When the positioning is done and the user is ready to strike the arc the helmet is immediately flipped into the position by quick snap or node of the neck of the operator, just before the striking.
- Uses infrared and ultraviolet coated dark-tinted glass
- Offers inexpensive and rugged safety protection
- Can be problematic as it might be difficult for the welder to position the gun or electrode when the helmet is in position
- The process of flipping the helmet up and down might cause neck fatigue. In some extreme cases can cause stress injuries to the neck
- Failure to position and lock the helmet in time before striking can lead to inadvertent arc flashes that can cause blackout
These helmets are the more advanced type. Usually, the helmet has a viewing lens of shade 3 or 4 when it is inactive which allows the wearer to see through it. The time the sensors on the helmet senses any arc start, the lens darkens to shade 8 to 13 according to the type of the heat received or type of welding by the sensors, in a fraction of a second.
- No need of flipping
- No risk of neck injury
- The sensor might wear out over time
- Needs battery
