ESAB F20 60 x 110 Parts FAQs
Filter lenses, cover lenses, visors, shells and headgear for a passive-filter flip-up welding helmet, and how to choose the right ones.
How do I work out which replacement lens or part fits my helmet?
Use the helmet manual and its parts list, any marking on the old part, and the label on the helmet. A welding-equipment maker's manual lists lens parts by size and shade number, and says not to use replacement parts other than those it specifies. Unauthorised parts and modifications can put the wearer at risk.
For a filter lens, note the shade number and the width and height of the old one, and compare the thickness and shape too. Keep the old part to hand when ordering. If you are unsure, send our team the helmet details and a photo before you order. Never trim or force a lens to fit.
Why must I replace a cracked or scratched filter straight away?
The filter is what stops harmful ultraviolet and infrared light reaching your eyes. Arc eye is inflammation of the cornea caused by ultraviolet from the arc, with symptoms such as sand in the eye usually appearing hours later. Prolonged infrared exposure can also gradually damage the lens of the eye.
A welding-equipment maker's manual says to inspect the helmet and glass for marks, cracks, pitting or scratches before work, because damaged surfaces reduce vision and impair protection. Do not weld with a damaged filter or protection plate; fit the correct replacement made for your helmet.
Does a welding helmet protect me from fume?
No. A helmet and its lenses protect the face and eyes from the arc, spatter and radiation, but they do not clean the air you breathe. For arc welders, a powered or supplied-air respirator that combines respiratory, eye and face protection, with a protection factor of at least 20, is the best option.
So parts for this type of helmet cover the eye and face side only. Use fume extraction and suitable respiratory protection as set out in your risk assessment, and check that anything you wear with the helmet is compatible with it.
What are the outer and inner cover lenses for and when should I change them?
The clear outer and inner cover lenses sit either side of the filter and take the spatter and scratches that would otherwise mark it. A welding-equipment maker's manual calls them consumables that must be replaced regularly, and says to replace protection plates that are scratched, damaged or built up with spatter.
Replace them when they are scratched, pitted, cracked or covered with spatter so that your view is impaired. They should be changed far more often than the filter, which the same manual says needs no further maintenance if used properly. Always use parts specified for your helmet.
