Operation principle
Functions and components:
This is the block diagram of an AC TIG -power source with active power factor
correction. A power source based on this principle can be loaded in TIG -process with
230 A current by a duty cycle of 40 % (1~ 230 Vac / 16 A slow fuse).
Primary- and secondary inverter control
Error code Description
Err 3 Over/Undervoltage
Err 4 Overheating
Err 6 Internal fault, secondary voltage over the limit.
Err 8 Maximum overheat time, machine doesn’t cool down fast enough. Only machine
shutdown and restart removes error.
Err 61 Water cooled gun connected but no water cooler in the system.
Cooler Cooler error:
- Cooling liquid over- / under pressure state
- Overheated alarm
BuS Err Communication between panel and power source isn’t possible
Err rSt System error, machine makes reset itself.
