Air pressure, air flow rate, air purity.we all keep hearing about this.and I find that over 50% of plasma system user don't seem to believe what we say.moisture or oil in the air will damage consumables in the first few seconds of use. The best starting point is to follow the recommendations in the Hypertherm manual.there are cut charts for FineCut consumables as well as 40, 60, 80 and 100 Amp shielded consumables.each set has its sweet spot for cut quality.ĥ. Matching the consumables and power level to the material and thickness is key to best cut quality. If you use the FineCut consumables at 35 Amps on 3/16".expect slower speeds and minimal taper. What consumable sets / power levels are you using for each particular material and thickness? If you operate at 100 Amps on 3/16" material.expect very high cutting speeds and a lot of taper. On what materials are you seeing the taper? Is the taper uniform around the perimeter of the cut.or does it change?ĥ. Please provide details about the machine and THC.machine motion, torch to work distance and pierce height and pierce delay times are definitely top ten suspects when cut edge angularity is an issue.Ĥ. Assuming it is on a machine.is there a THC (torch height control system)?ģ. Is the 1650 mounted on a machine.or hand held?Ģ. You have not provided much detail regarding "tapered cuts".so let me ask a few questions:ġ. In general.there is not normally an electrical problem that causes cut quality issues.
