Milt, the HF units claim up to 1/8 material for the 110 unit and 3/16 material for the 220 unit. Even if those are exagerated claims, I would think that 18 or 20 ga mild auto body steel would not be too much for them. What am I missing? You squeeze the material between two tongs, introduce a current, the metal melts together, the current shuts off and you are done. I doubt the cheap units have much to adjust, but once you get it set-up, I don't know why you say they won't work.
