We have cut perforated material a lot here in the shop. There are a few conditions though. It has to be done in manual mode, otherwise when the cutting arc moves from pilot to transfer arc the voltage reading will change dramatically causing the height control to respond. The second is that the plasma cutter has to be in the Perforated material cutting mode in order to maintain the pilot arc across the gap and as soon as it senses the material it activates the cutting arc again. The last is the cutting speed, if it's too fast the arc may not transfer in time to sever the material.
