Whos face is half cold and half hot after welding with an ordinary mask It's like being slapped in the face by a skewer grill This full-face auto-darkening mask dims when exposed to sparks, blocking you from strong light, sparks, and facial heat.

It can also be disassembled and cleaned, breathable and not stuffy - it can be used not only for welding, but also for cutting metal and polishing, and can also protect your face. You wont suffer any trouble by buying one for yourself. Its ten times more practical than giving a thermos cup as a gift to your friend/dad who loves to do welding work in the New Year. He wears a mask and has fun for a long time
