5.12.3 MMA welding data display
To the left and right of the LCD display on the control there are 2 “arrow keys” on each side for selecting
the welding parameter to be displayed. The
button is used to scroll through the parameters from the
bottom upwards and the
button is used to scroll downwards from the top.
As soon as changes have been made to the settings after welding (display on hold values), the display
switches back to the nominal values.
Figure 5-49
Four welding parameters can be selected in the MMA welding process:
Welding current and electrode diameter (left-hand side) and welding voltage and JOB no. (right-hand
side).
The parameters can be displayed before (nominal values), during (actual values) welding.
