Flux core wire?

Thats a nice one. True color eh? Interesting......

Yes, it doesn't have that heavy tinted color when you are welding.
Everything has it's normal color when it's in welding mode, and then in grinder mode it's like a light pair of sunglasses. (not actually clear)

It also has the solar battery charging system, but obviously it's not so much solar as it is UV charged from welding more than literal solar.
Seems to me anyway.:D
