G5-02 Helmet Parts FAQs
Spare plates, lenses, headbands and shells for an auto-darkening welding helmet, and how to work out which ones your helmet needs.
Can I fit plates or lenses from a different helmet range to save hassle?
It is safest not to. Helmet makers state in their user instructions that the helmet should only be used with the original spare parts listed for it, and some say the maker is not responsible for substitute components or modifications. Plates, lenses and headgear are normally made to fit one helmet family, and the fit affects how well the filter is held and protected.
Before ordering, check the part number in your user manual or on the old part, and match it to the helmet or filter name and version marked on your helmet. If you cannot find a match, our team can help you check.
My filter will not darken or flickers. Which part is the fault?
Work through the simple causes first. Manuals commonly list a wrong shade or function setting, dirty sensors or solar cells, a weak or flat battery, a low sensitivity setting for low-current work, and a spattered or pitted front cover plate. Wipe the sensors with a lint-free cloth, check the settings, check or replace the battery, then fit a fresh cover plate if the old one is marked.
If the filter still does not darken reliably, stop welding with it straight away and refer to the maker or your supplier. Never carry on welding with a filter you cannot trust: arc eye, a painful injury to the front of the eye that usually shows a few hours after welding, can follow exposure to the arc.
How should I clean and store the helmet and its lenses?
Manuals for auto-darkening helmets generally say to avoid solvents and abrasive cleaners. Wipe the helmet and plates with a soft cloth that is damp, not dripping, using mild soapy water, and keep the sensors and solar cells clean with a lint-free cloth.
Store the helmet in a clean, dry place away from direct sunlight and extreme temperatures, ideally in the storage bag so dust and scratches stay off the lenses. For long storage, some makers advise removing the battery where it is replaceable. Check your own manual for the exact method for your model.
Do replacement helmet parts have to meet any standards?
The HSE says eye protection for welders, including the filters that prevent arc eye, should conform to the relevant British and European standards. Older helmets and filters are marked to the older European standards for eye protection, welding protectors and auto-darkening filters. A newer international standard series is replacing these for new certification, and one part of it covers welding, so newer parts may carry different markings. Look for the markings given in your helmet's user instructions and keep them intact.
For a replacement filter, plate or shell, choose parts the helmet maker lists for your helmet, and follow your risk assessment. Do not drill, modify or mix parts in a way the maker does not allow, as that can invalidate the protection.
