The numbers on a welding helmet typically refer to the amount of light the lens will block. Depending on the specific helmet, they usually range from 9 to 13 – with 9 being the most light-blocking, and 13 being the least.
Generally, numbers between 9 and 11 are suitable for most light welding applications like MIG welding. For darker welding applications like Stick welding, a number of 12 or higher is usually recommended.
In addition, these numbers also indicate the amount of time it takes for the lens to switch from light to dark. For example, a 10-rated lens would take 1/25000 of a second to transition from light to dark.
Higher-numbered lenses, ranging up to 13, can take up to 1/50000 of a second for the same transition.
What do welding shade numbers mean?
Welding shade numbers refer to lenses that are used in welding helmets to protect welders’ eyes from the intense light emitted during welding. Shade numbers are used to indicate the amount and type of protection a particular lens provides, with a lower shade number indicating less protection and a higher number indicating more.
Shade numbers typically range from #8 (90% light transmission and least amount of protection) to #13 (up to 99% light blockage and maximum protection). However, some welding helmets and manufacturers may offer shades up to #14 or even higher, in order to protect welders from UV light or other hazardous materials or radiation.
The American National Standards Institute (ANSI) classifies welding shades from #9 to #13 as “suitable for normal welding operations”.
Different types of welding will require different levels of protection, depending on the material being worked with, the temperature at which it is being welded, and the nature of the arc created. Therefore, it’s important to determine the right shade number for your particular welding project, in order to ensure proper eye protection.
Are welding helmets one size fits all?
No, welding helmets are not typically one size fits all. Because welding helmets provide crucial protection during welding, it is important that they fit properly. Depending on the type of helmet, they typically come in a range of sizes and shapes to provide the best possible protection and fit.
Additionally, the helmets may have adjustable straps, headbands, and other features which allow them to be customized for the individual wearer’s needs. This is important since an ill-fitting helmet can pose a safety hazard if it doesn’t protect the face, neck, and eyes adequately.
Therefore, it is important to choose a welding helmet that not only meets your needs but also fits properly.
What setting should my welding helmet be?
The setting for your welding helmet will depend on the type of material you are welding and the amperage you are using. For example, with a metal, such as aluminum, you will want to use a lower setting, while with steel, it’s best to use a higher setting.
With DC welding currents, the range is usually from 9 to 13, while for AC welding current it’s usually 4 to 8. The best way to ensure you have the correct setting is to consult your welding helmet manual, as each helmet and welding process will have different recommended settings.
Additionally, be sure to check the radiation sensitivity of your welding helmet and adjust the filters accordingly. Finally, keep in mind that eye protection is important, so be sure to always set your helmet to the highest setting which will provide sufficient protection.
What shade is for welding?
Welding typically involves high heat and light, which is why the shade of the welding helmet is so important. The most common welding helmet lens shade is #10 (or ‘dark green’) which is suitable for most welding processes.
A higher shade number indicates more protection from light and heat, but can also make it more difficult to see the arc. Shade #10 is suitable for most types of welding and metal cutting, including: MIG welding, arc welding, TIG welding, plasma cutting, and Oxy-Acetylene welding.
Different shades may be needed if the metal being welded is extremely thick or if special welding techniques are being used.
What’s important to remember is that the shade of the helmet is not the only factor that determines the user’s protection. You should also consider the quality of the helmet, UV protection, and face protection when selecting the right welding helmet.
If you’re in doubt, it’s best to err on the side of caution and choose the highest shade you can.
Do auto-darkening welding helmets wear out?
Yes, auto-darkening welding helmets do wear out. This is because the components inside the welding helmet, such as the LCD/liquid crystal display, weld sensors, and batteries will deteriorate over time.
Such as a slower lens switching time, decreased clarity in the view, and frequent false triggering of the lens shading. If these signs are present, then it is likely time to replace the welding helmet.
Additionally, the sensors and electronics inside the helmet should be replaced every few years, even if they are functioning properly, as a preventative measure. It is important to replace auto-darkening helmets that are no longer functioning properly, as they can be a safety hazard when operating machinery or welding.
What does sensitivity setting do on a welding helmet?
Sensitivity settings on a welding helmet allow you to adjust the helmet’s ability to sense and react to the arc light created when welding. The sensitivity setting will reduce light levels to the level of your chosen setting.
It achieves this by regulating the current applied to the welding helmet’s sensors.
The sensitivity setting of your welding helmet is important because it ensures that you are properly protected when welding. If the sensitivity is too low, you won’t be properly protected from the bright light and could suffer eye damage.
On the other hand, if the sensitivity is too high, the welding helmet will be activated when light from other sources (such as the sun) come into contact with it. Therefore, it is important to find the right balance to ensure that your welding helmet is providing you with the proper protection.
What does Shade 5 IR mean?
Shade 5 IR is a type of welding helmet that uses a darker shade rating and an Infrared (IR) filter. The helmet is used when welding with higher-amperage electric welding processes, such as stick welding, MIG/MAG welding, Plasma welding, or TIG welding.
The darker shade helps to protect the welder from overexposure to the intense ultraviolet and infrared rays being emitted from the welding arc. The IR filter is designed to minimize exposure to infrared radiation generated by the welding arc.
This type of helmet is often recommended for welders working with amperage settings above 200- 225 amps, as the higher amperage can create more extreme infrared radiation. The Shade 5 IR welding helmet is a great choice for welders looking for increased safety and protection.
What is the darkest welding shade?
The darkest welding shade is generally considered to be a shade 14 welding lens. This shade is the darkest shade that is commonly available and is used for protection when welding in any relatively high amperage settings, such as 210A or higher.
If you are welding at very high amperage you may need to go darker, up to a shade 16. It is also important to note that even with a shade 14 lens you may need to add additional filters to achieve sufficient protection.
Do welders go blind over time?
No, welders do not go blind over time. Welding can present some potential vision risks, but these risks can be minimized and managed with proper protective gear and practices. For example, when welding with intense light, wearers should be sure to use a welding helmet fitted with the proper shade of filter lenses to protect eyesight from dangerous arc rays.
Additionally, wearing safety glasses, face shields, and eyewash in the areas around welders helps reduce any potential risks. Welders may also experience fatigue and eye strain over long periods of time, so it is important to take regular breaks and look away from the light of the welding area to rest eyes during projects.
If any safety concerns do arise, it is essential for welders to consult a healthcare professional for proper diagnosis and treatment. Ultimately, with proper gear and caution, welders can engage in their work with minimal risk to their vision.
Are pancake welding hoods better?
Pancake welding hoods, also known as passive welding helmets or low-profile welding helmets, have become increasingly popular among welders due to their low profile and lightweight design. The advantages of pancake welding hoods as compared to traditional welding helmets include better visibility and range of motion, as well as better protection from arc flashes.
Pancake welding hoods also typically offer more protection from fumes and gases, as well as superior coverage from ultraviolet and infrared radiation.

In addition, the low-profile design of pancake welding hoods also allows for increased peripheral vision, which is essential for welders who need to observe their welds continuously.
The lightweight design of pancake welding hoods also contributes to the overall comfort of the welder, as they don’t feel as heavy and oppressive as traditional helmets. Furthermore, their adjustable headgear ensures that the helmet fits properly and provides the necessary protection.
In conclusion, pancake welding hoods offer many advantages over traditional welding helmets. The visibility, range of motion, and lightweight design of pancake welding hoods provide many benefits to welders, while their superior coverage from various sources of radiation makes them a more effective protection against arc flashes and other radiation sources.
Overall, pancake welding hoods offer many benefits that make them preferable to traditional welding helmets.
Why do some welders use pancake hoods?
Welders may use pancake hoods to protect their face, neck and ears while welding. Pancake style hoods help maintain a comfortable fit that allows welders to move their entire head during the welding process.
The hoods boast a circular design and are made with a rigid plastic which can be easily adjusted. This provides a snug fit that does not move or slip off during the welding process.
Pancake hoods also help protect the face and neck from unpleasant fumes, sparks and glare which can be associated with welding. These hoods are designed to provide protection from ultraviolet and infrared light, which can be much more intense than regular sunlight.
This protection is especially important for welders who don’t wear the right protective clothing underneath their hoods. The hoods also keep the face and neck cooler, which helps welders remain comfortable during the process.
A pancake hood also provides an improved field of vision. The lightweight design is “flatter” than regular welding hoods, allowing welders better visibility while still providing adequate protection.
Welders that have large facial features or modest necks may find that other welding hoods, such as flip-up style helmets, don’t fit them properly. Since pancake style hoods are adjustable, they are more suitable for welders with different body shapes and sizes.
Overall, pancake hoods provide excellent protection for welders and the improved visibility helps them complete welding jobs more efficiently. The comfortable fit and adjustable design make them ideal for those who may have difficulty finding a more traditional helmet to fit them.
Are pancake hoods comfortable?
Pancake hoods are generally very comfortable to wear and great for those who enjoy having a hood that is low profile, light, and soft against their skin. Pancake hoods are specifically designed to fit close to the head, providing a snug, comfortable fit without being too bulky.
They are typically lightweight and offer some degree of flexibility, allowing them to move with the wearer’s body. Because of the close-fitting design, pancake hoods provide additional warmth by blocking chilly winter winds.
In addition, the adjustable drawstring on the hood allows ever more customizable levels of snugness. All of these features combined make pancake hoods an ideal solution for those who are looking for a comfortable, low-profile hood.
Can you wear a hard hat with a pancake welding hood?
Yes, it is possible to wear a hard hat with a pancake welding hood. This combination provides extra protection from dust, debris, sparks, and other hazards commonly encountered in welding environments.
When wearing a hard hat along with a pancake welding hood, it is important to make sure the hard hat and welding hood are compatible. Most welding helmets and hard hats have slotted holes in the front and rear of the helmet to accommodate the hard hat suspension system.
It is important to ensure that the diameter of the slotted holes of the welding hood is slightly larger than the diameter of the holes of the hard hat suspension system in order to ensure a secure fit.
Additionally, it is important to make sure the rear surface of the welding hood contacts the forehead area of the hard hat to ensure that all edges are sealed in order to properly protect the welding operator.
In addition to this, it is also important to make sure that the welding hood does not interfere with the hard hat suspension and harness, as this could potentially reduce the safety of the hard hat.
How do you sand a pancake hood?
Sanding a pancake hood involves smoothing out the material so that it is free of any bumps or imperfections. It is important to start with a coarse grit sandpaper and gradually move up to a finer grade for a polished finish.
Begin by laying down a drop cloth to protect the surface of your workspace. Secure the pancake hood on the drop cloth and use sandpaper with a grit of 80. Start sanding in long, even strokes. Make sure that you keep the sand paper flat against the surface and work in one direction so that you don’t leave behind any swirl marks.
Once you have finished the first coat of sanding, move up to a higher grit paper. Step up the grits in small increments, such as 120, 150, 180, 200 and so on. Work up to an ultra-fine grit such as 600.
Using finer grits will produce a smoother finish.
When you have finished sanding, use a damp cloth to remove any dust that is left behind. The final step is to apply a thin coat of paint or lacquer, depending on how you want the finished product to look.
Allow the lacquer to cure for a few days before you use the hood. With these steps, you can have a smooth, polished pancake hood.
