The first step to creating clean air in your work environment is to ensure that the best available welding process is used for your application. If applicable, you might consider using alternative welding methods. In addition to the welding process the material should be clean, remove oil, coatings and rust etc.
For quality reasons many of our customers already considered this first step. We recommend that you contact your welding machine supplier on matters of welding.
Unfortunately this first step is often not enough to ensure a safe work environment; additional steps need to be taken.
