Manual Mode - GYS HEAVYMIG 350-4 Manuel D'utilisation

«MANUAL » MODE
To set your device, proceed as follows:
- Choose the welding voltage using the 2 power switches according to the thickness to weld.
- Adjust the wire speed using the potentiometer (12).
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.
IMPORTANT : Make sure the product is not connected to the power supply before any intervention

EXPERT SETTING (ACCORDING TO STANDARD EN 1090)
In order to meet the EN 1090 standard, it is possible to calibrate the voltage, the current and the wire speed of this
product. Warning: the calibration must be done by JBDC or the distributor where they have a qualified maintenance
department using the correct equipment: resistive load (ref: 060135), tachometer (ref: 053953), voltmeter and amme-
ter (ref: 053984).
1/ Calibration of voltage and current (FIG-5):
The potentiometers P4 (voltage) and P5 (current) are adjustable directly on the electronic board.
2/ Calibration of the wire speed (FIG-4):
To access this mode, you need to press key (1) for 3 seconds. Then, press key (1) 3 times to display «Fc3». Now, you
can calibrate your wire speed to more or less 10% by step of 1% with keys (5) and (7). To exit this mode, press key
(1), the display shows «END».
HIDDEN MODE PARAMETERS (FIG-4) :
The hidden mode allows you to set the following parameters:
- Gouging mode (only for HEAVYMIG 450 GR / 450 WS) «Fc0»
- Selection of the wire speed potentiometer (only for HEAVYMIG 350 GR / 450 GR / 450 WS) «Fc1»
- Metal Selection «Fc2»
- Calibration of the wire speed (see above: expert settings) «Fc3»
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 HEAVYMIG 450 GR / 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 ».

HEAVYMIG 350-4 / 350 GR / 450 GR / 450 WS
When in manual this function displays the wire speed setting on display (10).
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 pro-
tect it.
