I have recently noticed that when I change my consumables (30Amp consumables) I have to slow my speed down from 130ipm to 120ipm and increase the amps from 25-29 to cut 2.0mm 14Gauge mild steel.
When I was seconds earlier cutting it with a used electrodes / nozzle and lower amps and faster speed. Can anyone tell me what is going on? (All genuine Hypertherm Consumables used)
This normally happens untill I am halfway through my electrode life and then I can speed up 10ipm and turn the amps down.
I am confused......
