GYS Magys 350-4 Betriebsanleitung Seite 13

MODIFICATION OF THE ORIGINAL PARAMETERS (FIG-4):
The device controls the arcing speed, the burn back and the post gaz. These parameters are set up in the factory,
but it is possible to modify them directly on the circuit board. Attention: this intervention must be done by a
qualified electrician.

HIDDEN MODE PARAMETERS (FIG-4) :
The hidden mode allows you to set the following parameters:
- Gouging mode (only for Magys 350 GR and 450 WS)
- Selection of the wire speed potentiometer (only for Magys 350 GR and 450 WS)
- Metal Selection
To enter this mode, press and hold button 1 for 3 sec. The machine will display « Fc0 », « OFF ». Press button 1
again to enter Gouging mode.
Gouging mode: (only for Magys 350 GR and 450 WS) (Fc0)
The top screen will display « Arc », « Air » and the bottom screen « OFF ».
To activate the power generator, push button 5. The display will show « Arc », « Air », « On ».
ATTENTION: once the power generator is activated, the output current is available on the unit. Do not put the torch
on the floor or in contact with any metallic part. Always wear protective clothing.
To deactivate the power generator push button 5. To leave Gouging mode and hidden mode, push button 1 and the
screen will display « END ».
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: (only for the Magys 350 GR/450 WS) (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
potentiometers 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.
P1: Set up the arcing speed to have a smooth start in order to avoid any spatter with the
first short circuit.
P2: Set up the Burn back to avoid the sticking of the wire on the contact tube.
P3: The setting up of the Post gas will regulate the time of gas used after the welding to
protect it.
P4-P5: DO NOT TOUCH
