TELWIN 802837 Tribe Automatic Welding Mask MMA/Mig-Mag/Tig, 0.1 V, Black

AVOID. There are NO settings on this, NO way to change the battery, and NO way to test that it's even working, or even that the battery has charge, without striking an arc and risking permanent damage to your eyesight. Whoever designed this thing must be literally crazy. It seems like the kind of cheap, poorly thought-out junk that some Chinese sellers are offering, but at twice the price of those ones. I looked all around it in bewilderment for a while, thinking I must be missing something. Then I tried testing it with the infrared from a remote control -- it did NOTHING. Might as well be a piece of dumb plastic, for all I can tell. Requested a refund at that point.Look to the SIP helmets instead -- they have test buttons, settings for darkness level, etc.
