Spares and consumables for a powered or air-fed welding helmet system: how to identify the right part, what wears, and how to look after it.
Start with the user manual and the markings on the unit and on the old part. The manual's parts list or exploded diagram will show the exact type, and the part number on the worn item (or the system's own label) helps confirm it. Note the helmet or system type and any serial or version details before you order.The HSE advises that, ideally, replacement parts come from the original manufacturer of the equipment, so that the system keeps performing as the maker intended. Parts that look the same can differ in fit, flow or approval, so check compatibility with the maker rather than guessing from appearance. If you are unsure, our team can help you match a part to your system.
The HSE lists the key maintenance tasks for powered respirators as changing replaceable filters, cleaning, checking the straps for damage, and checking the battery charge and flow rate. In practice, the items that wear most are filters and pre-filters, hoses, belts and straps, seals, sweatbands, and the cover lens on the helmet.How quickly each one wears depends on the work, the environment and the maker's instructions. Look over the whole system before each use, and replace anything cracked, stretched, torn, loose or contaminated rather than waiting for it to fail.
The hose carries the air you breathe, so it must be the right type for your system and your job. Different hoses are designed for different equipment, and the HSE warns that light-duty supply tubes must never be used for normal airline applications. The connectors, length and any pressure or flow requirements also depend on the maker's design.Check the manual for the correct hose type, and look at the whole length and the end fittings before each use for cuts, kinks, crushing, burns from spatter and loose connections. Replace a damaged hose rather than taping it. The HSE says to look after the supply tube during use, because the wearer's protection depends on it.
Follow the maker's cleaning advice. The HSE says that using cleaning products other than those the maker recommends may cause problems with the equipment, so avoid solvents and harsh chemicals unless the manual allows them. Clean and dry parts in a clean area so they are not contaminated again.The HSE also advises cleaning equipment before it is stored, and storing it as the maker instructs, in a clean place that protects it from contamination, damage and deterioration. Keep the helmet from resting face down on the cover lens, and remove or disconnect the battery for long-term storage if the manual says so. Check the parts again before the next use.
