«MANUAL» MODE (FIG-V)
To set the machine, proceed as follows:
• Choose the welding voltage using the 2*7 positions switch (depending on the product)
Example: position A-1 to weld 1 mm steel metal sheet with ø0.8mm wire.
- Adjust the wire speed with the potentiometer(2).
Advice:
The wire speed adjustment is often determinated « based on sound »: the arc must be stable and have a minimal crackling. If
the speed is too low, the arc is not continuous. If the speed is too high, the arc crackles and the wire pushes back the torch.
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(+).
F08: In manual and synergic mode, Squeeze time adjustment. Adjustment of the wire speed before current detection: The adjust-
ment range is between 50 and 120£ 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: 060418), tachometer, 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.
RISK OF BLESSING RELATED TO MOBILE COMPONENTS
The wire feeders contain moving parts that may catch hand, hair, clothes or tools which can lead to injuries! Take extra
care.
• Do not place your hand on mobile/pivoting/wire feeding parts of the machine!
• Make sure that all panels remain closed when in use !
Do not wear gloves when setting up the wire and changing the wire reel.
