Beta 90 with FA Pressure Flow Parts FAQs

Spare parts for an air-fed welding helmet used with a pressure flow supplied-air set: how to identify the right part, what wears and how to look after it.

How do I work out which spare part fits my air-fed helmet?

Start with the old part and the equipment itself. Look for the part number or marking on the worn item, then check the data plate or label on the helmet and the supplied-air unit and compare them with the parts list in the manual. Helmets from the same maker often come in several versions, so a part that looks the same may not fit.

If the old part has no readable marking, note the helmet type, the air-supply set it is used with, and the measurements of the part. Our team can help you match it, but the manual and data plate are the most reliable guide.

What do the pressure flow parts in an air-fed helmet system do?

In a supplied-air system, the control set and belt parts manage how the air from the supply reaches the hose and helmet. Parts in this group usually include the belt that carries the unit on the body, the control or regulating fittings, and small items that wear or get damaged in a workshop.

The exact arrangement depends on the maker and the version, so check the parts list in the manual to see what a set contains and whether the belt can be replaced on its own. Never alter or adapt the air-supply parts in any way the manual does not describe.

What should I check on the helmet and air set before each use?

The HSE says respiratory protective equipment must be thoroughly inspected before each use, and that records of regular examinations, maintenance and repairs should be kept for reusable equipment. In practice that means looking over the helmet, head cover, seals, hose, belt and connections for damage, wear, cracks or loose fittings, and checking the air flow in the way the maker's manual describes.

If anything is damaged, or the flow check is not passed, do not weld in the helmet until the fault is put right. The user's risk assessment and the maker's instructions set how often more detailed examination is needed.

How do I choose the right filter lens shade?

Shade depends on the welding process, the current used and how bright the arc is. The standard for welding filters sets out recommended shade numbers for each process and current range, and the maker's chart for your helmet is the best reference. Charts usually allow one shade either side of the listed number to suit the job and your eyesight, so go a shade darker if the glare is uncomfortable.

Do not go lighter than the lowest shade the chart or the maker permits, because too light a shade can let harmful radiation reach the eyes. Do not choose a shade just for visibility without checking the chart. If you are unsure for a particular job, check it against your risk assessment or ask your supervisor.
