Indications that a replacement is necessary are: cracked or broken lenses, slow or uneven auto-darkening function, pitting or helmet shell damage that can be seen, headgear degradation, or if the helmet is over 5-7 years old and used on a daily basis. Are cheaper welding helmets safe to use? Cheap helmets can provide very little protection but must at least meet minimum safety requirements (ANSI Z87.1 and EN379). Professional welders must be persuaded to invest more in quality helmets for better protection, comfort, and longer durability in the long run.
