I have a Hypertherm 1000 (on a Dynatorch table), running alot of 14 ga material with Hypertherms finecut 220329 40A nozzles (silver). I have heard that the Thermacut consumables last longer than the Hypertherms, but there is no direct cross reference for this number. Any experience or comments with Thermacut?
I also have some of the Hypertherm regular 40A nozzles (copper), but have not used them for cutting 14ga yet. They are certainly heavier built than the finecut nozzles, but I don't know how well they will do with fine cuts...
Also, regarding electrodes - do you run them until they fail, or is there some point where you switch them out before failure? How do you decide when to switch?
