When I purchased this plasma cutter, I figured the heaviest metal I would be cutting would be 1/2: with a bit of 3/4" now and then.
The smaller machine would have had a lesser duty cycle, I tend to forget about time when I'm working and have no regard for duty cycles.
To avoid burning out the machine went for the larger 70 amp machine that is capable of doing a severance cut of 1 1/4" giving me 100 percent duty cycle cutting the metals I cut most often.
Yes it's Chinese, bought from a fellow off of ebay direct from China, uses the Panisonic P80 torch and consumables are cheap compared to name brand equipment.
Had a few problems with the machine which I figured out and likely know more about it than the guy that sells them. All were easy fixes.
Owned it for 2 years now and work it to death,sometimes my back is so sore that I just walk away from it leaving it outside in the weather rain or shine.
Using the machine to recover brass and stainless steel valves is a snap, to give you an idea some pictures.
