I haven't seen one up close, but when I was at Norco getting a tank of gas a couple of months ago I asked them, and they said they have been around a couple of years and are basically cheap junk from China. It's essentially a MIG welder with a laser instead of electric current, electric current works fine, why change. The other new laser use on the market is rust removers. You can get stuff from Temu for $100.00, or industrial stuff for $10,000.00 and up, nothing in between. The $10,000.00 stuff works very well by the way.
