104 Transfer Lost
Arc transferred to metal for at least 50 ms. then went out.
Causesfor104code:
• Cutdemandsetmuchlowerthanrecommendedfortorchparts,i.e.100Aconsumablesintorchbutcut
current set for 30 or 50A (or zero). Current may be too low to keep arc on.
• Torchstandofftoohighforcuttingprocessbeingused.
• PlasmagasowtoolowduetoaleaksomewherebetweentheplasmaregulatorortheDPC3000andthe
torch. Check for leaks.
• Remoteanalogcurrentcontrolswitchessetwrong.

then cut demand will be zero, pilot will be weak, depending on torch height it may still transfer but
will immediately go out.
o IfremoteanalogcurrentcontrolisnotbeingusedbuteitherSW11issettothedownpositionorSW8-2
