Dynamic Pierce works by receiving plasma’s Dynamic Pierce signal
( Kjellberg plasma has this signal) or plasma’s arc feedback signal.
After IHS, THC controls plasma start arc, and it lifts torch up when arc
strikes. It is to protect the torch tip and electrode; consumables can
work longer in this way.
G. Manual Operation
Many functions can be Manually operated on Operation Panel of
XPTHC-100, such as, set Auto/Manual mode of THC, manually control torch
Up and Down, IHS test, Arc Start test…..etc.
H. Arc Voltage Divide
Isolation Voltage Divide, the Voltage Divide ratio is 100:1/50:1. Once
Isolation Voltage Divide function damaged, user can also use Non-isolation
Voltage Divide on our voltage divider.
1.6 Work process
1.6.1 work with IHS,
When CNC send out Arc Start Signal(IHS enabled), THC starts with IHS, then send
Arc Start Signal to plasma, after plasma start, THC delay lead in arc voltage from
plasma( set pierce delay time), THC send Arc Feedback(arc ok) Signal to CNC to
start Cut after arc voltage lead in. If THC is on Auto Model, and CNC Auto Control
enabled, then cutting is under THC Auto control.
1.6.2 work without IHS
When CNC send out Arc Start Signal (IHS disabled), THC starts without IHS, lifts
torch to the set height (set via button SET-IHS), then send Arc Start Signal to
plasma, after plasma start, THC delay lead in arc voltage from plasma ( set pierce
delay time), THC send Arc Feedback(arc ok) Signal to CNC to start Cut after arc
voltage lead in. If THC is on Auto Model, and CNC Auto Control enabled, then
cutting is under THC Auto control.
We don’t recommend work without IHS
