Welding Helmet Buying Guide

Not too sure which helmet is right for you? Check out this buying guide to help you choose! 

One of the most essential pieces of equipment when welding is a welding helmet.

The welding helmet plays multiple health and safety roles during the welding process. The correct helmet should provide complete protection, from flying materials to the blinding lights. The purpose of this welding helmet buying guide is to ensure you not only select the correct helmet for your welding applications but for the safety of the welder themselves.

Passive Vs Auto Darkening

A passive lens helmet has a fixed shade, the 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 can flip the helmet into position before striking the arc. For the operator who doesn’t weld often they can find it difficult to position and hold the electrode while snapping the helmet into place.

Auto Darkening

Auto darkening helmets allow for wearing during the positioning of the electrode, gun or torch. This is due to the range of shade lowering usually down to shade 3 or 4, allowing for positioning of the welding equipment, whilst the helmet is in place. When the sensors detect the arc, the lens darkens. This can potentially improve weld quality as there is no movement required before welding can commence.

Fixed/ variable shade

On fixed shade auto darkening helmets, when an arc is detected the helmet will automatically change to the shade opted for on the control dial of the helmet, this doesn’t mean it’s the correct one for the application. If you tend to weld the same application with the same number of amps, this could be the helmet for you. However, if you are continually changing between jobs a variable shade helmet maybe the ideal solution.

Commonly welders do not change the shade for different amps or applications nor do they know exactly what shade they should be on (see table below for correct shades). If you don’t know the right shade for your application, then let the helmet choose for you, choose a model of helmet which can detect and automatically select the correct shade level. This is a new Optrel feature which can be found on their E684 and Panoramaxx helmets, this is also known as autopilot lens detection.

Lens Reaction Time

When switching from setting up your weld to the actual welding consider the lens reaction time, in most cases the quicker the better. The more arc’s you strike in a day the more you’ll appreciate a quicker speed. Some helmets have an adjustable display control, this allows for the lens to stay darker for a period once the arc has stopped, this would be beneficial when welding at high amperages, as molten metal may still emit harmful rays while it cools.

Optical Clarity

The optical clarity defines the quality of view you get through the helmet, you wouldn’t buy a cheap pair of sunglasses, so don’t let the quality slip when it comes to welding, after all you only get one set of eyes!

Optical clarity is governed by European Standards for the welding industry, the standard is known as EN379. Ratings are determined by tests that measure light transmission across the cartridge as well as lights from the cartridge layers. The ratings are displayed as numbers, each defining an aspect: Optical class (distortion), diffusion of light (blurry image), variations on luminous transmittance (even shade) and angle dependence. Ratings are graded on a scale of 1 to 3 in each class. A score of 1 is perfect, while 3 is the worst rating. So, the perfect clarity score is 1/1/1/1.

Viewing Size

The bigger the better right? Not necessarily in this case! Consider your environment when selecting the viewing size of your helmet. The bigger the viewing size, the bigger the helmet and possibly the heavier the helmet.

Number of Sensors

Helmets usually range from 2 sensors to 4. The more sensors the better coverage, if you are welding in restricted areas sensors could be obstructed, therefore the more the better.

Other Things to Consider

Availability of cheater lenses

Power source – Battery powered or battery and solar powered

Comfort — Ensure the helmet has a good fit or has changeable head gear. When wearing the helmet for longer periods, ensure weight is kept to a minimum.  

Powered Air Purifying Respirator (PAPR) – Do you require a fresh air unit on your helmet or may require one in the future? Check out the availability of an upgrade to a fresh air unit. PAPR are air fed helmets which supply filtered air back into the helmet to ensure the welder does not breathe in welding fumes.
