My 12 year old son is excited to learn about welding. So excited, that at Christmas he bought me an auto darkening helmet. A couple of months ago we went to a neighbor's who had a good stick welder and we practiced welding together. The new helmet wouldn't stay up when we were inspecting the welds. So we kept tightening the knobs on the sides. After a couple of times, one of the knobs broke off. It was plastic and cheesy. The auto-darkening part worked okay. Just the plastic helmet part seemed lame. We took it back to the farm store where my son bought it and got a refund. We looked at the other ones and they all had plastic knob stuff on the sides. We drove to oxarc yesterday to look at the proper stuff only to find that they were closed. Then it occured to me that it would be better to talk to you guys than talk to a sales man. Is there a brand I should be looking for? Are they all plastic these days? Any advice?
