COMMAND KEYBOARD (FIG-V)
Choice of welding mode (2)
- NORMAL (2T) : standard welding 2T
- NORMAL (4T) : standard welding 4T
- SPOT : spot function, with adjustment of the spot diameter
Wire speed adjustment (4) Adjustment wire speed potentiometer.
The speed varies from 1 to 20m/minute.
SPOT adjusting potentiometer (5) : To adjust the welding time of a
point, the size of the point and the time between each point.
Manual mode (1)
In manual mode, the wire speed is determinated by the user by
adjusting the potentiometer (2).
Synergic mode (3)
Position the potentiometer (4) in the centre of the zone «OPTIMAL
SYNERGIC »
In this mode, the device determines the optimal wire speed accor-
ding to 3 parameters:
- Voltage
- Wire diameter
- Wire type
It is still possible to adjust the wire speed +/- with the potentiome-
ter (4).
«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).
In manual mode only , this function displays accurately the wire speed setting.
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.
