I am a professional who has been working with metal for nearly 5 decades, cutting ,welding and fabricating. I must admit, I was a little skeptical at first but after putting it through the paces, I became more and more confident in this machine. It does everything that the big name machines do at 1/5th the price, actually in my opinion it does it better than most of them. if you are looking for a portable compact plasma cutter or even if you need one to have in your shop, do not hesitate to buy this machine, you will not be disappointed. I have zero complaints so far. This unit far exceeds any expectations I have for a 50 amp plasma cutter.
