Flux core wire?

Mine's a Miller. Was something around $90 at the welding supply place. It seems to work well. The problem with the cheapies is the response time on the lens. If you're only doing a couple welds you'll never notice you're getting exposure. Weld all day and blister your eyeballs. The prices at the supply houses are usually in line with what you see online and you can check them out. Lincoln and others offer similar helmets in that range.
