Straight answers to the questions people ask most when choosing and fitting replacement parts for a powered air welding helmet.
Check the exact helmet type and, if it has one, the version marked on the helmet and in its manual. Helmets from the same family can look alike but take different plates, covers and filters.If you are unsure, our team can help you match parts to your helmet. Photos of the helmet markings and of the part you are replacing are a great help.
The outer protection plate shields the filter lens from spatter and scratches, and the inner plate sits between the lens and your face. They are wear parts whose job is to protect the filter lens.Change them when they are scratched, pitted with spatter or hazy enough to hurt your view. A worn plate makes it harder to see the weld and can be a safety problem.
Replace them when airflow drops, when they are visibly dirty or damaged, or at the interval in the manual. A loaded filter makes the blower work harder and can shorten battery life.Filters are part of what gives a powered respirator its protection, so never run the helmet without the filters the manual calls for. Check the data plate and manual for your own unit.
They remove certain gases and vapours from the air, in addition to the particle filter that deals with fume. Each type is marked for the kind of gas or vapour it handles.You need one if your risk assessment shows gases or vapours that the particle filter alone does not deal with. Pick the type your assessment calls for, and check that it is approved for use with your helmet.
No. A gas filter is made for specific gases or vapours and is marked with the type it handles. An odour pad is generally meant for nuisance smells, so check the manual for your own unit before assuming it gives any protection against harmful gases.Choose any gas filter by your risk assessment, and make sure it is listed for your helmet in the manual. Ask a competent person if you are unsure.
The battery life shortens with use, so replace it when it no longer holds a charge for a working shift. Fit a battery made for your helmet system.The cover protects the battery and its contacts from dirt and knocks. Replace a cracked or loose cover, because dust and spatter can reach the contacts.
