looks like it should do the job. It's marketed mainly for cutting metal roofing panels. That's what mine was marketed as, and they work great for both. I'll suggest something, before you buy that one though. If you have a metal dealer in the area, that sells metal building panels, call and see if they have one in stock and what they get for it. Although it was almost 5 years ago now, I didn't pay anywhere near $80 for mine, it was about the cost of the harbor freight one. Maybe I just got a good deal on oneIn my book, cutting one piece of HC is worth it. Although I'm currently using tin snips...wahh
ohh look, Harbor Freight has HD metal shears for $47. @PapaChaz would these work on the HC or welding wire?
