Types of welding hoods
1. Passive hoods
Passive hoods are a type of welding hood that use a fixed shade lens and do not have any additional features, such as a headgear or ventilation. They are typically the most basic and economical option for welding protection.
Passive hoods are designed to protect the welder’s face and eyes from the intense light and radiant heat generated by the welding arc, as well as from harmful ultraviolet (UV) and infrared (IR) rays. They can be used for a variety of welding processes, such as shielded metal arc welding (SMAW), gas tungsten arc welding (GTAW), and gas metal arc welding (GMAW).
The fixed shade level of passive hoods is determined by the type of welding process and the thickness of the material being welded. The American Welding Society (AWS) recommends a minimum shade level of #10 for most welding applications, but a higher level may be needed for certain types of welding or for welding thicker materials.
It is important to note that passive hoods do not provide ventilation, so it can be uncomfortable to use for prolonged period of time, and also do not provide respiratory protection from harmful fumes and gases.
2. Auto-darkening hoods
Auto-darkening hoods, also known as “variable shade” or “smart” hoods, are a type of welding hood that use an electronic lens that automatically adjusts the shade level based on the intensity of the welding arc. They are designed to provide optimal visibility and protection for the welder during the welding process.
The electronic lens in an auto-darkening hood is made up of a liquid crystal display (LCD) and a series of sensors that detect the intensity of the welding arc. When the arc is struck, the sensors detect the increase in light and signal the LCD to darken the lens to the appropriate shade level. When the arc is not present, the lens returns to a clear state, providing optimal visibility for the welder to set up and position the workpiece.
Auto-darkening hoods can be used for a variety of welding processes, such as shielded metal arc welding (SMAW), gas tungsten arc welding (GTAW), and gas metal arc welding (GMAW), and are suitable for welding with all types of electrodes, including stick, TIG, and MIG/MAG. They have a wide range of shade levels, typically from #9 to #13.
They are more expensive than passive hoods, but they offer the convenience of automatic shade adjustment and improved visibility, making it easier and safer to weld. Some auto-darkening hoods also include additional features such as a headgear, ventilation, and built-in air-purifying systems to provide respiratory protection from harmful fumes and gases.
3. Powered air-purifying respirator (PAPR) hoods
Powered air-purifying respirator (PAPR) hoods are a type of welding hood that use a battery-powered blower to filter and circulate clean air around the welder’s face, reducing the risk of inhaling harmful fumes. They are designed to provide both respiratory and eye protection for the welder during the welding process.
A PAPR hood has a battery-powered blower unit that pulls air through a filter, removing harmful particles and gases, such as ozone and particulate matter, before circulating it around the welder’s face. The filtered air is then supplied through a hose or tube to the hood, providing a continuous supply of clean air for the welder to breathe.
PAPR hoods are suitable for a variety of welding processes, including stick, TIG, MIG/MAG, and plasma cutting. They are also suitable for use in environments with high levels of fume and particle exposure, such as in industrial settings, and are commonly used when performing overhead welding or in tight spaces where the welder’s head is close to the workpiece.
PAPR hoods are more expensive and bulkier than passive or auto-darkening hoods, but they provide respiratory protection from harmful fumes and gases, making them a good choice for welders working in environments with high levels of fume and particle exposure. Additionally, PAPR hoods are also available with auto-darkening feature, which provides both respiratory and eye protection in one device.
4. Supplied air hoods
Supplied air hoods, also known as “air-fed” hoods, are a type of welding hood that use a hose connected to a compressor to deliver clean air to the welder, eliminating the need for a built-in air-purifying system. They are designed to provide respiratory protection for the welder during the welding process.
The air supplied to the hood is filtered and cleaned by a separate compressor unit, which is typically located at a safe distance from the welding area. The clean air is then delivered to the welder through a hose or tube, providing a continuous supply of fresh air to breathe. This allows the welder to work in environments with high levels of fume and particle exposure, such as industrial settings, without the risk of inhaling harmful fumes.
Supplied air hoods can be used for a variety of welding processes, including stick, TIG, MIG/MAG, and plasma cutting. They are also suitable for use in environments where the welder’s head is close to the workpiece, such as in tight spaces or when performing overhead welding.
Supplied air hoods are more expensive than passive or auto-darkening hoods, but they provide the highest level of respiratory protection, making them a good choice for welders working in environments with high levels of fume and particle exposure. They also require a separate compressor unit and a clean air supply, which can add additional costs and maintenance to the welding process.
5. Full-face helmets
Full-face helmets are a type of welding hood that cover the entire face, including the eyes and ears, and often have additional features such as ventilation and a built-in air-purifying system. They are designed to provide comprehensive protection for the welder during the welding process.
Full-face helmets typically have a hard outer shell that protects the welder from impact and debris, as well as a protective lens that covers the entire face, including the eyes and ears. The lens is usually made of polycarbonate, which is strong and heat-resistant, and can be either fixed or auto-darkening.
The helmet shell can also be equipped with ventilation systems to keep the welder cool and comfortable during prolonged use, and built-in air-purifying systems, such as a PAPR, to provide respiratory protection from harmful fumes and gases.
Full-face helmets are suitable for a wide range of welding processes, including stick, TIG, MIG/MAG, and plasma cutting, and are particularly useful for welders working in environments with high levels of impact and debris hazards, such as shipbuilding, construction, and heavy industry.

Benefits of a carbon fiber hood
Carbon fiber hoods are a type of welding hood that are made from carbon fiber, a lightweight and strong material that offers several benefits for welders. Some of the benefits of a carbon fiber hood include:
1. Lightweight
One of the main benefits of a carbon fiber hood is its lightweight nature. Carbon fiber is significantly lighter than traditional materials such as steel or aluminum, which can make it more comfortable to wear for extended periods of time. This can be especially beneficial for welders who work in environments where they need to wear the hood for long periods of time, such as in shipyards, construction sites, or other industrial settings.
A lightweight hood can reduce fatigue and increase the welder’s productivity by allowing them to work for longer periods of time without experiencing discomfort or strain on their neck and shoulders. This can be especially beneficial for welders who are working in overhead or other awkward positions, where a heavy hood can add to the stress on their body.
Additionally, a lightweight hood can also make it easier for the welder to move around and position themselves in tight spaces or areas with limited access.
It is important to note that a lightweight hood alone cannot guarantee the safety of the welder, it is important to check the compliance of the hood with the welding safety standards and also to check the features such as ventilation, auto-darkening, and respiratory protection if required.
2. Strong and durable
Strong and long-lasting, carbon fiber is renowned for both. It is a composite material made from carbon fibers and a resin matrix. The carbon fibers are tightly woven together, giving the material its strength, while the resin matrix holds the fibers in place and provides additional protection against impact and other types of damage. This makes carbon fiber a very popular material for use in high-performance and racing applications, where strength and durability are critical. It also has a wide range of applications in aerospace, industrial and infrastructure industries as well.
3. Heat resistance
Carbon fiber is also known for its heat resistance. It has a high thermal conductivity and a low coefficient of thermal expansion, which means that it can withstand high temperatures without expanding or contracting significantly.
Additionally, carbon fibers have a very high thermal stability, which means that they don’t degrade or lose their strength at high temperatures. This makes carbon fiber an ideal material for use in high-performance and racing applications, where components are exposed to high temperatures from engine and exhaust heat.
It is also used in various industrial applications such as furnace liners, heat exchangers, and high-temperature structural components.
4. Low thermal expansion
Carbon fiber has a low coefficient of thermal expansion, which means that it expands very little when exposed to changes in temperature. This property makes it an ideal material for use in applications where dimensional stability is important, such as in precision equipment, aerospace components and automotive parts. The low thermal expansion of carbon fiber also makes it a suitable material for use in environments where components are exposed to extreme temperatures, such as in high-performance engines, furnace liners and heat exchangers.
The low thermal expansion of carbon fiber also makes it a suitable material for use in environments where components are exposed to large temperature changes, such as in aerospace, where aircraft are exposed to extreme temperatures during flight. The low thermal expansion of carbon fiber helps to prevent warping and distortion in the components, which can cause them to lose their shape and integrity. This allows for more accurate and reliable components to be produced.
5. Low electrical conductivity
Carbon fiber is not a good conductor of electricity. It has a relatively low electrical conductivity compared to metals such as copper or aluminum. This property makes it a suitable material for use in applications where electrical insulation is required, such as in electrical equipment and components, high voltage power transmission, and lightning protection systems.
The low electrical conductivity of carbon fiber also makes it a suitable material for use in environments where electrical interference is a concern, such as in aircraft and other vehicles, where electronic equipment is sensitive to electrical interference. The low electrical conductivity of carbon fiber helps to prevent electrical interference from affecting the performance of electronic equipment, which can cause it to malfunction or fail.
Additionally, the low electrical conductivity of carbon fiber makes it a suitable material for use in high-voltage applications, such as in electrical power transmission, where the low conductivity of carbon fiber helps to prevent electrical arcing and other types of damage.
6. Corrosion resistance
Carbon fiber is generally considered to be corrosion resistant, but its resistance can vary depending on the type of resin used in its production and the manufacturing process. Carbon fiber reinforced polymer (CFRP) is typically more resistant to corrosion than other composites such as glass fiber reinforced polymer (GFRP) because of the nature of carbon fibers, which are not affected by most chemicals and are highly stable in various environments.
Carbon fiber reinforced plastic (CFRP) typically does not corrode in most environments, but it can be attacked by strong acids, bases and certain organic solvents. However, if it’s exposed to these environments, it’s important to use the appropriate coatings or treatments to protect the carbon fiber from corrosion.
In most of the cases, carbon fibers are protected by the resin matrix and are not directly exposed to the environment. The resin matrix typically provides a barrier to protect the carbon fibers from corrosion. Additionally, carbon fibers have a high resistance to environmental aging, which means that they don’t degrade or lose their strength over time when exposed to UV light, moisture, or other types of environmental factors.
