MODIFICATION OF FACTORY SETTINGS
The product manages the burn back and post gas. In manual mode, it is possible to adjust factory settings through the hidden menu.
Enter the hidden mode by pressing the «MODE» button (2) for 3 seconds.
Move through the different functions with the «MODE» button (2).
F06: Burn back adjustment. This function enables to avoid the wire to stick to the contact tip at the end of your weld. The adjustment
range of this product is between -10ms to 70ms with the buttons TYPE (-) and WIRE(+).
F07 : Post gaz adjustment Adjustment on how long the gas protects the welding pool at the end of the weld. The adjustment range
is between 0ms to 950ms with the buttons TYPE (-) and WIRE(+).
EXPERT SETTING (STANDARD EN 1090)
In order to comply with EN1090, the product supports WPS (Welding Procedure Specification) and helps to achieve WPQR (Welding
Procedure Qualification Record). It is possible to calibrate the voltage, the current and the wire speed of the product. Warning: the
calibration must be done by GYS or its qualified distributor. Required equipment : Dummy load (ref: 060135), tachometer (ref:
053953), voltmeter and ammeter (ref: 053984).
1/ Voltage and current calibration:
The functions F00 (voltage) and F01 (current) are adjustable through the hidden menu. These functions are available by pressing the
«MODE» button for 3 seconds. The setting range varies from -20% to +20%, by 1% step.
2/ Wire speed calibration:
WARNING: To display the wire speed, a calibration is required for each welding configuration.
The functions F02 (internal motor) and F05 (sparated wire feeder) are adjustable through the hidden menu (you can access it by
pressing the MODE button for 3 seconds) The setting range varies from -20% to +20%, in 1% increments.
To exit hidden menus, move through the different functions with the MODE button until you see «END».
«SYNERGIC» MODE (FIG-V)
With this function, there is no need to adjust the wire speed.
• Put the wire speed potentiometer (4) in the middle of the« Optimal synergic » zone. • Select:
-The wire type (3)
-The wire diameter (3)
-The power (switch on the front panel), to select the right position in accordance with the thickness of the part to weld, please refer
to the table «Synergic mode» (fig. VI). From this combination, the device determines the optimal wire speed and the device is ready
to weld. It is also possible to adjust the wire speed if necessary by adjusting the potentiometer (4) + or – manually. A memory of
the latest welding configurations is made and is recalled each time the machine is switched on or each time a trigger of one of the
torches is pressed.
ADVICE AND THERMAL PROTECTION
• The product must not be carried by its handles, torch supports or the upper panel but by the underside of the product. The gas
bottle must not be attached to the product during movement.
• Respect the basic rules of welding.
• Ensure the ventilation holes of the device are not blocked to allow adequate air circulation.
• Leave the device connected after welding to allow cooling.
• Thermal protection: The light turns on and the cooling duration is a couple of minutes influenced by the ambient temperature
DUTY CYCLE AND WORKING ENVIRONMENT
The post describes has an output characteristic of type « constant tension ». Its duty ratio according to EN60974-1 standard is indi-
cated in the following table :
x/60974-1 @ 40°C
Promig 350-4S DUO et G DV
Note: The warming test was done at room temperature and the duty cycle at 40°C were determinated by simulation.
• These are Class A devices. They are designed to be used in an industrial or professional environment. In a different environment,
it can be difficult to ensure electromagnetic compatibility due to conducted disturbances as well as radiation. This equipment must
be used and stored in a place protected from dust, acid, gas or any other corrosive substance.
• The Promig comply with IEC 61000-3-12, provided that the power of the short-circuit Ssc is equal to or greater than 3.9MVA at
the interface between the machine and the mains power network. It is the responsibility of the installer or user of the equipment to
ensure if necessary by consulting the operator of the mains electricity, that the equipment is only connected to a power supply where
the power of short-circuit ssc is equal to or greater than 3.9MVA.
