Kemppi GTH3 XFA Helmet Parts

Beta 90 XFA Helmet Parts FAQs

Answers on springs, hatch parts, lenses, headgear, sweatbands and magnifiers for a powered-air welding helmet, and how to be sure you order the right part.

How do I identify the right spare part for my helmet?icon-minus-redicon-plus-red

Use the helmet type shown on the shell or labels together with the spare parts list in the manual. Welding-equipment makers list each wear part with an item number, a part number and a quantity, so you can quote the exact number when you order.

Do not choose by looks alone. In one maker's quick guide, items that look alike in two helmet ranges, such as the headband and outside protection plate, have different part numbers. If the old part carries a number, note it, and keep the manual to hand.

How do I change a protection plate without damaging the filter?icon-minus-redicon-plus-red

The method depends on the helmet, so follow your manual. In one welding-equipment maker's manual for a comparable helmet, the outer plate is reached by releasing the filter holder, and the inner plate is lifted out by flexing it with a fingernail in the recess.

Avoid tools and avoid touching the filter surface. Handle the filter by its edges. Clean the sensors while the helmet is open, and never refit the filter without both inner and outer plates. Replace a damaged plate immediately rather than carry on.

Why should I inspect the helmet before every use?icon-minus-redicon-plus-red

Makers say so, and respiratory protective equipment must be thoroughly inspected before each use. A welding-equipment maker's manual says to inspect the helmet before each use and replace damaged or worn parts.

Check lenses, filter, headgear, covers and any moving parts. Welding radiation can cause arc eye, an injury to the front of the eye that typically shows up hours afterwards, so a damaged lens or a gap is not worth the risk. Report defects and follow the maker's maintenance schedule.

Can I use parts from a similar helmet range?icon-minus-redicon-plus-red

Not unless your manual says so. A welding-equipment maker's manual says only that maker's own parts and accessories should be used with its protective equipment, and warns of serious harm to health if this is ignored.

Ranges that look alike often have different part numbers, sizes or fittings, so a part that appears to fit may not seat or seal as designed. Check the part number against your own helmet's parts list. If you cannot find it, ask our team to help you identify it.

How do I choose the right shade for a replacement filter?icon-minus-redicon-plus-red

Shade depends on the welding process and the current, and the manual's chart gives the recommended levels. A welding-equipment maker's manual says shade levels are set according to the welding process, so check your chart rather than guessing.

A variable-shade auto-darkening filter lets you set the level, while a fixed-shade lens has one number only. Make sure any replacement covers the range and the filter size your helmet takes. If your work spans several processes, a variable filter is usually more flexible.

How should I store the helmet and look after the filter battery?icon-minus-redicon-plus-red

Store the filter dry and out of extreme heat. A welding-equipment maker's manual for a comparable helmet gives a storage range and says prolonged heat may shorten the battery life. It suggests keeping the solar cells in the dark, for example filter face down, so that the filter powers down.

Replace the battery when the low-battery light flashes. Battery type and storage limits differ by model, so follow your own manual.
