Practical answers on choosing, using and looking after welding and weld-and-grind helmets, including flip-up and air-ready styles.
There is no single interval. Replace the clear outer cover lens whenever it is cracked, deeply scratched, pitted by spatter or too dirty to clean with a soft cloth. A damaged cover lens makes the arc harder to see and, on an auto-darkening helmet, can interfere with the sensors.Cover lenses are normally specific to the helmet, so check the manual or markings for the correct part. Replacing a cover lens is far less involved than replacing the filter itself, so it is worth checking it regularly and changing it early.
Shade depends on the process and the current: a higher current gives a brighter arc and needs a darker shade. Published shade charts are only a guide, and different charts give slightly different numbers, so start from the chart in your helmet manual and adjust to what you can comfortably see.If you are unsure, begin with the darker shade rather than the lighter one, and never go lighter than the maker recommends for the process. Low-current TIG, plasma cutting and heavy-current MIG or stick can all call for quite different settings. Our team can help you match a helmet to your work.
Arc eye is an injury to the front surface of the eye caused by the ultraviolet radiation from welding. The eye usually becomes painful and red a few hours after exposure, and it often feels gritty. Most cases are temporary, but other parts of the eye can also be damaged by welding radiation.The usual cause is striking an arc before the helmet is in place, or being exposed to someone else's arc. If you suspect arc eye, stop work and get medical advice. Always lower the helmet or check the filter is dark before you strike the arc.
Yes. Anyone close to an arc, including helpers, assistants and passers-by, can be exposed to harmful radiation and may develop arc eye. The risk depends on how close they are and how long they are exposed, and there is no distance that is simply safe. People working near the arc need protection suited to the work, such as filtered eyewear with side protection, as set out in your risk assessment.Where possible, screen off the welding area with screens or curtains made for welding, and keep unprotected people well away from the arc. A helmet protects only the person wearing it.
