Welding Toxic Fumes

The art of welding has a downside. Unfortunately welding produces toxic fumes and ultraviolet radiation is present in the welding arc. These fumes have been proven to cause cancer in humans such as lung cancer, kidney and bladder cancer. The ultraviolet radiation can also cause skin cancer.

One website claims that the US Department of Health reports that welders are at a 40% higher risk of being affected by lung cancer than any other professional groups (source: https://www.blackwoods.com.au/blackwoodsknows/welding-respirator).

Long term welders must protect their health from many years of exposure and a respirator plays a critical role in protecting the welder.

Welding Fumes

Welding fumes are extremely toxic and contain many harmful components. Very fine, solid particles of metal oxides containing metals such as arsenic, copper, iron, lead and many more coupled with harmful gases such as carbon dioxide, carbon monoxide, nitrogen oxides and more, can all be found in welding fumes.

The exact composition of the welding fume is heavily depending on the type of welding being performed and materials involved.


There are many factors that contribute to the level of exposure a welder will have to welding fumes. Some of these include;

  • Ventilation.
  • Operating position.
  • Coatings and/or paint on the materials being welded.
  • Length or duration of continuous welding period.

What Is A Welding Respirator?

A welding respirator is a protective piece of equipment that usually covers the mouth and most importantly the nose.

The respirators on the market today come in various styles and designs. They all serve one purpose which is to remove the toxins from the air that you are breathing in. However the level of effectiveness varies depending on many factors.

Hi everyone, my name is Samuel but all of my friends call me Sam. I have been a very hands on person ever since I was a kid. Back in those days I was more interested in wood work and have always been a very keen gardener. I find physical projects very rewarding and love having something practical that I can use that I have made with my own hands.

As I have progressed with my DIY skill set I have focused more and more on working with metal. Now my favorite projects are combining my metal working skills with my wood working skills.
