Note
1. In synergic mode, you can rotate the knob counter-clockwise to reduce the voltage and rotate it
clockwise to increase the voltage within the range of 30 V ± 9 V.
2. In synergic mode, the welding voltage must be finely tuned according to the plate thickness.
Manual
The welding current and welding voltage are adjusted independently. The procedure is as
follows:
1. Press the Manual button on the control panel.
2. Rotate the current adjusting knob to adjust the current and the voltage adjusting knob to
adjust the voltage.
3.4.7 Arc Dynamic
Arc dynamic is used to set the arc hardness. The procedure is as follows:
1. Press the Arc dynamic button on the control panel.
2. Use the knob to adjust the arc hardness.
3. Figure 3-16 shows the control panel where the parameters have been set.
Figure 3-16 Setting arc dynamic
Note:
Arc hardness can be adjust within the range of -9 to +9. Rotating the knob clockwise increases
the hardness, while rotating the knob counter-clockwise reduces the hardness. Table 3-2 and
Figure 3-17 describe the arc dynamic.
