Adjusting para-
meters for cor-
rection
1
Press the Parameter selection button to select the parameter you wish to correct
2
Use the adjusting dial to set the selected parameter to the desired value. The para-
meter value is displayed in the digital display located above it.
HotStart function
To obtain optimum welding results, it will sometimes be necessary to adjust the HotStart
function.
Benefits
-
Improved ignition, even when using electrodes with poor ignition properties
-
Better fusion of the base material during start-up phase, meaning fewer cold-shut
defects
-
Largely prevents slag inclusions
See the "Setup menu: level 2" section for details on setting the available welding para-
meters.

Function:
during the specified hot-current time (Hti),
the welding current is increased to a cer-
tain value. This value (HCU) is higher than
the selected welding current (I
H
).
SoftStart function
The SoftStart function is intended for basic electrodes. Ignition takes place at a low weld-
ing current. Once the arc is stable, the welding current continues to rise until it reaches
the welding current command value.
