Summary
1. Components
1)
Power source
S L G - □□□ HF
Inverter air plasma cutting power source SLG-200HF
、
SLG-300HF
、
SLG-400HF
，
is a constant current power source. All
outside cable connect terminal same. This power source can communicate with CNC controller through RS-485. The plasma
cutting system can only control by the ON/OFF switch on the machine.
2)
Arc initiator
Plasma arc initiator QFK-E1 is used for the HF pulse start, then cause guide arc,when the guide arc reach the workpiece,
it will cause main arc.Another function for the arc initiator is to receive the control signal from power source, to replace
plasma preflow gas and cutting flow gas.The arc initiator must work together with the plasma power source
3)
Torch : Torch HYC-400B transfer the current to workpiece through arc to get metal cutting.
