Helmet Spares FAQs
Straight answers to the questions people ask most when choosing and replacing spare parts for welding helmets.
How do I find the right spare part for my helmet?
Start with the make and model of your helmet, which is usually printed on the shell, the filter unit or the inside of the helmet. Many parts are specific to a model or range and are not interchangeable between makers, and sometimes not even between versions of the same helmet.
If you can, note down the part number from the old part or the manual. Measure the size of lenses and plates, because sizes vary. If you are unsure, our team can help you identify the correct part.
Can I use replacement parts that are not from the helmet maker?
Sometimes compatible parts fit, but you need to be careful. Parts supplied for a helmet by its maker are designed and tested for it, while other parts can differ in fit, optical quality and protection.
A poorly fitting lens or cover can let in light, spatter or radiation, and fitting parts the maker does not approve may affect the approval of the helmet. Check the manual for your own helmet to see which parts it allows, and make sure any replacement is stated to suit your model and to meet the same protection requirements.
Do auto-darkening filters need batteries, and how do I change them?
Many filters use solar cells plus a battery, which may be a replaceable button cell or a sealed unit. Some run only from the battery, and others have a charge indicator. If the display dims, the response slows or the filter will not switch on, check the battery first.
Follow the maker's instructions to replace it, and use the correct type. Sealed batteries cannot be changed by the user. Some filters have a test button to check operation, and it is good practice to test before every shift.
When should I replace the headband and sweatband?
Replace the headband when the adjustment ratchet slips, the plastic is cracked or the helmet no longer sits firmly on your head. A helmet that wobbles or tips forward is tiring and may move at the wrong moment.
Sweatbands soak up sweat and dirt, then harden and become unhygienic, so replace them regularly, especially in hot conditions. Many are sold in packs. A fresh headband and sweatband can make an old helmet feel like new.
