Rated 2 out of 5 by 1reviewer.
Rated 2 out of 5 by I purchased the 9400i miller and was seriously disapointed. the lens was ok didnt care for the green but thats just prefrence i guess. It can get heavy when you lift the lens to grind The inner grinding lens will scratch very very easily. dont not wipe it with anything other then the cloth they sell for it. It also cost 9 dollors to replace. every lens cover get smoked out fast when welding with stick or mig. Its a very awsome looking helmet but realistcly its only good for tig or some really clean welding enviorments. December 7, 2012
