Gouging process:
- Turn the voltage switch to maximum,
- Open the cylinder valve or compressed air network,
- Contact between the electrode and the metal piece will create a circuit. The intense heat will melt the workpiece and
air will pass through the arc quickly enough to blow the molten material away.
- Conversely to the MMA process, the work is done by pushing the arc.
The visible length of the electrode must between 100 and 150 mm.
The torch is connected to the back of the generator, on the + terminal for steel and stainless steel electrodes. For copper
electrodes you can use any terminal. For Nickel electrodes connect the electrode holder to the – terminal. The earth
clamp is connected to the other terminal.
Always follow the instructions as indicated on the electrode packaging.
Protective clothing should always be worn when gouging!
Selection of the wire speed:
(Fc1)
Wire speed can be adjusted using wire feeder potentiometer or generator
potentiometer. Only one potentiometer can be active at a time.
On this type of equipment with separate wire feeder, 2 wire speed potentio-
meters are available. You can choose to use between both but they can't be
activated at the same time.
To enter into « Selection of the wire speed potentiometer » mode push button
1 for 3 seconds and then press the same button again. The top screen will
display « Fc1 » and the bottom one:
-
« Out » for the separate wire feeder potentiometer
-
« In » for the generator potentiometer.
To choose between Out and In, press button 5. Press button 1 to leave this
mode and enter another mode.
Metal selection (Fc2)
This mode will allow you to select or de-select a specified combination of 3 types of metal (Fe CO², FeCrNi ArCO²,
Aluminium). To enter this mode, follow the instruction to enter hidden mode and press button 1 twice. The screen will
display « Fc2 ». In order to choose the combination of metal (8 selections available), press button 5 until you reach the
combination required. The « Manual » position can't be deactivated.
To leave the hidden mode press button 1, the screen will display« END ».
MAINTENANCE
• Maintenance should only be carried out by a qualified person.
• Ensure the machine is unplugged, and that the ventilator inside has stopped before carrying out maintenance work.
(DANGER High Voltage and Currents).
• It is recommended removing the steel cover 2 or 3 times a year to remove any excess dust. Take this opportunity to
have the electrical connections checked by a qualified person with an insulated tool.
• Regularly check the condition of the power supply cord. If damaged, it will need to be replaced by the manufacturer,
its after sales service or a qualified person.
• Before each use, check the state of welding cables of the torch and earth clamp (The conductive metal should not be
exposed).
• Calibration: Check once a year the good calibration of the tools calculating welding current and voltage. Consult the
maintenance plan of the welding unit.
