All welding parameter set values remain stored until the next time they are changed.
This applies even if the power source is switched off and on again in the meantime.
Start welding
To display the actual welding current during welding:
-
Press the "Parameter selection" button to select the welding current parameter
- The actual welding current is shown in the digital display during welding.
Corrections dur-
ing welding To obtain the best possible welding results, the dynamic welding parameter will sometimes
need to be adjusted.
Press the "Parameter selection" button to select the dynamic welding parameter
Use the adjusting dial to set the desired dynamic value
The welding parameter value is shown in the digital display located above it.
Dynamic
for influencing the short-circuiting dynamic at the moment of droplet transfer
0 harder, more stable arc
100 soft, low-spatter arc
HotStart function To obtain optimum welding results, it will sometimes be necessary to adjust the HotStart
function.
Advantages
- Improved ignition, even when using electrodes with poor ignition properties
- Better fusion of the base metal in the start-up phase, meaning fewer cold-shut defects
- Largely prevents slag inclusions
For details on setting the available welding parameters, please refer to "Setup parame-
ters", "Setup menu - level 2".

: Main current = set welding current
How it works
During the specified hot-current time (Hti),
the welding current is increased to a certain
value. This value (HCU) is higher than the
selected welding current (I
H
).
Anti-stick func-
tion As the arc becomes shorter, the welding voltage may drop so far that the rod electrode will
tend to "stick". This may also cause "burn-out" of the rod electrode.
