I would like help from people who actually have used BOTH helmets for tig, and can describe me, or even better put pics or videos of the actual view while tig welding. I read that for some people the A50 does not work for low amperage tig, while I saw one video of someone using it for aluminum tig with no problems. Will appreciate your input regarding quality of view, tint of light, and which one looks more natural. Also, description of the difference in view on the A50 with the amber vs clear lenses. Thanks.
