Welding Helmet Keeps Fogging Up

Welding helmets are one of the best tools for the welders to protect themselves from the harmful lights, fumes, and sparks. Sometimes, using welding helmets may not be an easy task for some users. There are a lot of aspects that the welders have to look into before wearing it on the head.

The significant issues while using welding helmets include the “fogging up.” Some users may find their welding helmet fog up due to many reasons. At times it requires a very simple technique to solve the problem.

No matter what kind of welding helmet you use; the fogging up problem is possible with any welding helmets. Hobby welders may not feel the fog like a great problem, but welders that work for long hours should take care of the fog formed during welding to ensure safety and creation.

Intricate welding works will require a keen and proper focus to complete the deed. To achieve excellent output, the welder has to do the work without any disturbances. In this page, we will see the reasons that pave the way for fog up in the welding helmet and the simple techniques to avoid fogging up.

Reasons why welding helmet fog up:

1) The temperature of the welding helmet and the breath: Sometimes, the temperature of the welding helmet might be low when compared to the temperature of the breath. It is mostly experienced by welders that work in the cold regions.

It can be avoided by placing the welding helmet facing the sun to warm up or can blow hot air to warm the lens instantly.

2) Distance between the face and the lens: Welding helmet can fog up when the face is very close to the welding mask. Whenever the user breathes the air, there will be fog developed over the lens, which may be hard for the user to view the focus point.

Fogging up can be avoided by adjusting the distance between the face and the helmet so that there will be free circulation of air which can maintain the temperature.

3) Breathing mostly through the mouth: Some welders have the practice of frequently breathing through their mouth. The user can breathe through the nose to minimize the cause of fogging.

The temperature of air from the nose will be quite colder than that of the air from the mouth, which is the cause of fog.

Ways to overcome:

  • Can use mild shampoos for cleaning the lens before and after welding.
  • Can mount the small fan to blow warm wind from above the head.
  • Can use respirators to avoid the fog up.
  • Can try after altering the space between the face and the shield.
  • Can try breathing through the nose rather than the mouth.
  • Can try best anti-fogging products that are sold best in the market.
  • Can keep the helmet in the warm place to get warmer so that it can counterpart the breathing temperature.
  • Can try cleaning the lens using shaving cream, dish wash liquid or vinegar mixed with hot water.


Using any anti-fogging products may have adverse reactions for some users; the lens may lose its clarity to work accurately after the applications. It is better to gain detailed knowledge from the seller of the product before using it on your favorite or expensive welding helmet.

The fogging up may be on the visor or the glasses – it depends on the welding helmet and also on the welder’s style of using. There are also welding helmets available with the fan circulator in the market which can avoid fogging. Hope, this page gave you the causes of welding helmet fogging up and also the solutions to get rid of the distractions.
