- TWIN MIG Function
in double synergic mig for EXTERNAL WIRE FEEDER for Multi Plus series ma -
chines.
To select TWIN MODE, in the following procedure.
Press switch MODE (SW5) untill on led twice.
For change the double pulse frequency parameters press the SELECT (SW6) button
untill led of requency set led twice flashing. The display show value of frequency.
You can change the value by (sw1) and - (sw2).
The double pulse frequency can be set from 0,5Hz to 4,0Hz.
In the TWIN mode the balance is fic at 50%, and two levels of current are fixed preset.
“TWIN SPECIAL MODE ” FUNCTION : SPC
To select TWIN SPECAL MODE, in the following procedure.
Press switch MODE (SW5) untill on led twice (frequency value mode).
Change value of frequency by + button (sw2) untill display show “SPC” .
Now it is possible modify frequency, balance and level, for modify this parameter enter
in the thecnical parameter mode.
To enter in the thecnical parameter mode by press 3 seconds the SELECT (SW6)
button.
