A selection of respirators for welding are here for your protection. We carry a variety of particulate respirators, half and full face respirators, to the most advanced powered air respirator systems (PAPR). We have the welding respirator that you need in order to keep yourself protected. Finding which welding respirator will offer you the maximum protection is easy.
To select the proper respirator for welding for maximum protection against particulates, determine the following conditions:
Once an assessment of the environment has been completed, you can select the right welding respirator.
Air-Purifying respirators - These welding respirators can either be a filtering facepiece, full-face or half masks with mechanical or chemical cartridges to filter dust, mists, fumes, vapors or gases and are available in three types.
Powered Air-Purifying Respirators (PAPR) - these welding respirators use a blower to pass the contaminated air through a filter, purify it, the deliver it to a mask or hood. PAPR's filter mists, dust, fumes, vapors and gases, similar to ordinary welding respirators. These welding respirators cannot be used in oxygen-deficient atmospheres, which can result when another gas displaces the oxygen or consumption of oxygen by a chemical reaction occurs. Oxygen levels that are below 19.5% will require a source of supplied air or supplied air respirator protection. Levels below 16% are considered life threatening.
Optional Features
Other features are available to help customize your needs for the right respirator for welding. Nose cups are available and reduce lens fogging and lens covers protect the lens from paint, minor chemical splashes and scratches.
Toxic Fumes and Gases
Studies show that full-time welders are at increased risk of bronchitis, airway irritation, lung function changes, and lung cancer. Redent studies suggest a link between welding fum and nerve disorders. Respiratory hazards in welding can be divided into two main categories:
Welding Fumes
The primary airborne contaminant found in arc welding is welding fume. Welding fume is a complex mixture of very small particles of metal oxides. The specific components depend on the composition of the welding electrode (stick, wire or filler rod), base metal, surface coatings and the type of shielding gas or flux.
Gases and Vapors
When electrode coatings, fluxes, shielding gases and surface coatings are burned or exposed to ultraviolet arc rays, they can generate potentially harmful gases, such as carbon monoxide, ozone, nitrogen oxides, gaseous fluoride and phosgene. Whenever feasible, local and area ventilation systems should be used to remove harmful fumes and gases. However, in many cases engineering controls alone cannot reduce exposure levels adequately. In these situations, it may be appropriate to use respirators. For most welding applications, an array of welding respirator options exist that offer specific benefits and limitations.
