I have A whitney Advantage with a hsp 130 hypertherm palsma , i've had it for 5 yrs . not had to many problems . Good machine . But about a week ago on 30 amp the machine would not fire . The wire that runs from torch head tothe machine was arking everywhere . on 80amp and 130 machine fires normal . replaced the wire with wire that isn't the 3oo dollar wire that hypretherm sells . It fires every once in a while then a blue spark that looks like a welder without ground is what it does when it dosen't . anyone esle had this problem ? I've replaced the 30amp board , like i said the wire i've ordered but it will here wednesday .(300 dollar wire)
