Advanced settings (MMA welding)
To enable the greatest possible breadth of applications, the following parameters can be adjusted
or optimised for the welding task.
5.6.1
Arcforce correction (welding characteristics)
Note for "PICO CEL machines":
The arcforce characteristic for cellulose electrodes "
" has been optimised at the factory
for the "Thyssen Cell70 electrode" which requires relatively strong arcforcing. The experience has
now demonstrated numerous times that the factory-set arcforcing is too strong for a "light"
electrode, such as those from Böhler, and therefore had to be adjusted downwards to between -3
and -4.
Every 4 arcforce characteristics can also be optimised individually for the relevant electrode types
and their welding properties, in addition to the selecting the electrode type.

more arcforce – harder arc

Example:
You are using a rutile/basic electrode type and set "
" accordingly on the machine
control. When welding the electrode type, you specify a hard or aggressive arc. You should now
change the arcforce setting in the direction of "less arcforce – softer arc" until the required result
is achieved.
