PRACTICAL ADVICE
-
If the air contains moisture and/or oil is good to use a dryer filter to prevent excessive oxidation, consumption and damaging of
parts of the torch.
- Impurities in the air cause the oxidation of the electrode and nozzle, and may make more difficult the striking of the pilot arc.
If this condition occurs clean the terminal electrode and the inside of the nozzle-end with sandpaper
-
Ensure that the new electrode and the nozzle are about to be mounted are well cleaned and degreased.
To avoid damaging the torch always use genuine parts FIMER.
THE OPERATIONS REQUIRING ACCESS INSIDE THE MACHINE MUST BE EXECUTED AFTER DISCONNECT THE
POWER PLUG FROM THE OUTLET!
TECHNICAL DATA
The inverter is a special oscillating circuit that, supplied by an input continuous voltage, provides an output AC voltage having the
frequency required. Increasing the frequency, achieves multiple benefits:
-
Use of power transformers, small and light;
- High Bandwidth of the output cutting current, resulting in a current always appropriate to the process;
-
Eliminate the annoying hum of common electromechanical equipment.
