«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.
