i have a lincon flip right now and i hate it..the lens is to small and dark..i got a 10 shade in it and i cant see anything...i looked at the atos at hf tools but they only go down to 9..i welded with a 6 or 7 one time and it was great...also used a cheater flip one time and that was great as well..any help here??
. Although it's just personal preference. A guy at work has a 13. Ya can't see a damn thing out of it, and another guy has a 10 but he will use other people old protective lenses ,turning it into about a 18. Just all depends.
