How Do Welding Helmets Work?
Arc welding produces three types of light that can damage a welder’s eyes: ultraviolet, infrared, and visible. A welding helmet is developed to secure a welder’s face and eyes from these dangers.
Choosing the best welding helmet for your specific needs can be frustrating. With numerous brands and sources of details, it can frequently be tough to identify which welding helmet is right for you. In helping to narrow it down, the team at AWS suggest you think about these essential aspects when choosing a welding helmet or Welding PAPR:
Using quality personal protective devices and safe welding practices should be a top concern for welders, no matter the type of welding process.
Welding PPE includes, however, is not restricted to, eye, body, face and hand security. The shatterproof glass ought to constantly be used under the welding helmet. In addition, the welding environment must be assessed to make sure the proper ventilation and breathing defence.
The heavier the welding helmet, the higher the pressure you could feel in your neck. If you’ll be welding for a number of hours at a time, a heavy one could be uncomfortable or unpleasant. Welding helmets with plastic shells tend to be lighter.
Does Helmet Weight Matter?
Yes. A lighter weight welding helmet will decrease neck strain and reduce tiredness with extended usage. Selecting your helmet weight will depend upon the mix of all of the other aspects along with how long each day you intend on utilizing it.
Auto-Darkening Vs. Passive Lens
Welding lens shade numbers refer to the lens’ ability to filter light. All auto-darkening welding helmets that fulfil the Australian standard AS/NZS 1338, provide 100% protection versus hazardous infrared and UV rays and may vary from a # 8 shade for low-amp applications as much as a # 13 shade for high-amp applications.
Do I Need a Single Fixed Shade or Variable Shade Lens?
A standard welding helmet, likewise in some cases described as a passive welding helmet, features a viewing lens with a fixed ultraviolet (UV) and infrared (IR) filter, generally a # 10 shade. This filter provides the very same level of security no matter the number of amps the light emits from the weld.
When a welder is ready to work, he will need to decrease this kind of helmet with a quick nod or breeze of the neck to turn the helmet down while keeping the torch in position. The welder has to lift the helmet to see when work is total.
Performance: How Powerful is the Lens?
Contrary to popular belief, it is unimportant the variety of photo-sensors an auto-darkening welding helmet has, offered they consistently identify the welding arc. The question, therefore, is not how many sensors does the helmet have, but rather how powerful is the lens?
General Functions Of An Auto-Darkening Helmet
Welding light state:
How light or dark the welding filter is when not welding, the lighter the welding filter, the better the welder can see the workspace and weld piece. Miller ® auto-darkening helmets have a light state of 3.
When the welding arc is struck, identify how dark the welding filter gets. Market basic shades are 8-13 with 13 being the darkest. See the chart below to identify the appropriate shade number for your welding applications.
What about Personal Choice?
