1. we saw your video, but need more information to identify the problem:
(1). what is the work volt during cutting?
(2). After plasma stop cutting, if you press the remote “↓down” button, can it keep going to cut?
(3). does the plasma always stop fire at the sample point of the drawing?
2. By the way, can you confirm the plasma you use is hypertherm max200?
and did you replace any parts of the plasma recently?
if yes, please tell us what parts you replaced recently.
