I've said it in 50 different welding threads -- if you can't see -- you can't weld. Period. You have to be able to see what you're doing. But then again -- I'm kind of an equipment kind of guy.... the right stuff for the right job.
There's 4 different helmets - used for different things... A couple of them (the ones hanging on the TIG machine - are capable of lower settings -- so I can TIG at very low amperage and still see...
One of the helmets on the MIG machine is set up more for sheet metal tacks if I don't just want to close my eyes.
