i have a relatively new maxpro 200, it sat idle for 6 months or so, now i installed a new cnc machine and planned to use it. The torch is fitted with 200 amps consumables for mild steel cutting. Plasma and shield gas is set to AIR AIR. There are no errors whats so ever but the the plasma struggles to even cut 6mm mild steel. Feed rate is kept at 1000mm/min and still it can hardly pierce the piece. All consumables are new and part numbers checked. After just cutting a 50x50mm piece it managed to burn the nozzle, while cutting i would hear some spluttering sounds from the torch. Any ideas?
