1
Move the mains switch to the "I" position: all the indicators on the control
panel will briefly light up
2
Press the "Process" button to select the MMA welding process:
The welding voltage is applied to the welding socket with a three second time
lag.
If the MMA welding process is selected, any cooling unit present is automat-
ically deactivated. It is not possible to switch it on.
NOTE!
Under certain circumstances, it may not be possible to change welding
parameters that have been set on a system component (such as remote con-
trol or wirefeeder) from the control panel of the power source.
3
Press the "Parameter selection" button to select the amperage parameter.
4
Use the adjusting dial to set the desired amperage.
The amperage value is displayed in the left-hand digital display.
All welding parameter set values that have been set using the adjusting dial
remain stored until the next time they are changed. This applies even if the
power source was switched off and on again in the interim.
5
Start welding
To display the actual welding current during welding:
-
Press the "Parameter selection" button to select the welding current para-
meter
-
The actual welding current is shown on the digital display during welding.
Corrections dur-
ing welding
To obtain the best possible welding results, the arc-force dynamic parameter will
sometimes need to be adjusted.
1
Press the "Parameter selection" button to select the arc-force dynamic para-
meter
2
Use the adjusting dial to set the desired arc-force dynamic value
The welding parameter value is shown in the digital display located above it.
Influence of the short-circuiting dynamic at the instant of droplet transfer:
- = hard, stable arc
0 = neutral arc
+ = soft, low-spatter arc
