Fronius TC2000 Torch Cleaner Operation

The Fronius TC2000 is not a conventional torch cleaner like the Tregaskiss TT4A that uses air pressure and a cutting bit to clean a torch nozzle. The TC2000 is powered by 120VAC, and it uses a magnetic field to pull welding slag out of the torch nozzle by energizing a capacitor that is discharged through an internal coil.

When power is applied to the unit, the over-temperature and fill level indicators will flash yellow even though the unit might not actually be over-temperature, and the fill level might be full.

For the overtemperature and fill level indicators to behave normally with everything wired correctly, the capacitor needs to be energized. This is accomplished by outputting 24v to the “high – quick stop” signal in the cleaner. The capacitor requires 50 seconds of charging time to reach the maximum magnetic flux density required for a full cleaning process. However, the system allows you to perform a cleaning cycle after a minimum of 20 seconds of charging time. Once the controller receives the ready signal, outputting 24v to the “high – cleaning start” signal will discharge the capacitor, creating the magnetic field to pull slag from the nozzle. To keep the capacitor in a constantly charged state between clean cycles, users can either add logic in the ladder so the high – quick stop signal is turned on with controller power or add logic in job structure. Although ladder logic would be a more practical solution than job structure.

Here is a standard wiring diagram, and a short video of the operation https://www.youtube.com/watch?v=cPe3fxZaP3E

If the overtemperature and fill indicators continue exhibiting errors while the high – quick start bit is high, consult the manual for troubleshooting tips.
