I have a new bulltear table using a hypertherm 45. My torch is trying to cut way too high. I have it set to pierce at .15 and cut at .06. I am trying to cut 1/4 material and it cuts the first couple inches fine then raises up higher and won't cut all the way through. I am new to this and can't figure it out. THC is on. Cutting 45 ipm. Preset volts 137. It does this on other thickness of metal too. The volts are staying pretty close to the 137 and the torch is moving up and down during the cut so I think the THC is working. Any suggestions on where to start looking?
Thanks
