•
Press and hold down rotary switch 'E2' for a few
seconds, or the icon
changes as shown below.
E1
•
Turn one of the rotary switches and select the icon
for the MMA welding process; to confirm, press
'E2'. Alternatively, tap the icon on the screen.
•
Turn one of the rotary switches and select the
welding polarity; to confirm, press 'E2'. Alternatively,
tap the icon on the screen.
•
Other parameters can be set by selecting the
SETTINGS icon.
•
To manage the programs and jobs, refer to the
sections that follow.
•
The settings are confirmed by selecting the HOME
icon; following confirmation the main screen

•
Arcforce: percentage increase in welding current in
the case of short circuits; helps to prevent the
shutdown of the electric arc.
•
Arcforce V: minimum voltage threshold (Volt) that
activates Arcforce. It is useful for special electrodes
to reduce sticking.
•
Dynamics: adjusts the current according to the
position of the electrode.
•
VRD: the time in seconds after which the generator
reduces the output voltage to Vdc, making the work
environment safer.
