Beta 90 with FA Flow Control Parts FAQs

Answers on choosing, fitting and looking after the spare parts for a belt-worn, powered-air welding helmet system with flow control.

How do I find the right replacement part for my helmet system?

Start with the data plate or label on the fan unit and the helmet, then match what you read to the parts list in the user manual. Note the part number printed or moulded on the old part if there is one, and write down which generation of helmet and fan unit you have.

Parts that look alike can differ in fit, so do not rely on appearance or on a part that merely seems to fit. The parts need to keep the equipment working as originally intended. If the markings are worn away, our team can help you work out the right part from the details you can read.

When should I change the filters, and what do they not protect against?

There is no single interval. Filters have limited capacity and can clog, making the airflow drop, so they should be changed when necessary and in line with the maker's instructions. Heavy fume, dusty conditions and long shifts all shorten filter life. A low-flow warning, shorter battery run time or reduced airflow are common signs that a filter is loaded.

A particle filter does not remove welding gases. HSE notes that particulate filters will not protect against the gases in welding fume, so if gases are a concern, the maker's instructions and your risk assessment should decide the filter type.

How do I care for the battery and know when it is worn out?

Use only the battery and charger the maker specifies, and check the battery for damage before each use. Stop using a damaged pack. HSE guidance asks that battery-powered equipment is fully charged before use, and that battery charge is checked as part of routine maintenance.

A battery that gives noticeably shorter run time, or will no longer hold a full charge, is nearing the end of its life. Nickel-metal-hydride packs generally keep best when kept clean, stored as the maker advises and not left deeply discharged. Charging limits and storage temperatures vary, so follow the manual.

What should I do if the airflow drops or the fan stops?

Leave the work area immediately. HSE guidance says never to keep working if the fan stops or the flow rate falls. A loose-fitting helmet may still give some protection if the fan fails, but you should move to a safe area and find the cause.

Common causes are a clogged filter, a flat or worn battery, a kinked or damaged breathing hose, or a poorly seated filter. Do not go back to welding until the fault is fixed and the flow has been checked as the manual describes.
