Did you happen to see this topic:
Although it is not the model you are speaking of, one member, @alexincali was having good success with the YesWelder Cut-55ds until it recently burned up.
I don’t have any experience with the YesWelder plasma cutter. I had chimed in on the other thread to say I was happy with the welder I got from YesWelder but cautioned another member that I was concerned about the lack of documentation with that welder and suggested a similar situation would probably exist with the plasma cutter.
Edit: I am sure you know this but just to be sure…YesWelder Cut 65DS comes in two versions: Non-HF start and regular. You would not be successful with the regular one.
