Hello, I have a torchmate 2 with a hypertherm 85. I finally had time to put the machine together and start doing all the tests. I started to do a line test ( and even a small part I made) and the machine will do the cordinates of the part just fine, However the plasma torch looses its arc after a period of time. I say time, because it will do the full line ( in torchmates line test) at a high speed, but as the speed slows down for each line the length of each line does as well. On the part I drew, it cut the holes (4 of them) and then cut about a inch and a half of the perimeter, then lost its arch. The air blowing out of the torch continued until the machine stopped.
