205 MMA Synergy
Allows you to set the best arc dynamics, selecting the
type of electrode used:
1 Standard (Basic/Rutile)
2 Cellulose
3 Steel
4 Aluminium
5 Cast iron
Default standard (1)
Selecting the correct arc dynamics enables maximum
benefit to be derived from the power source to achieve
the best possible welding performances.
Perfect weldability of the electrode used is not guaran-
teed (weldability depends on the quality of the consum-
ables and their preservation, the operating and welding
conditions, the numerous possible applications, etc.).
312 Arc detachment voltage
Allows you to set the voltage value at which the electric
arc switch-off is forced.
It permits improved management of the various operating
conditions that occur. In the spot welding phase, for exam-
ple, a low arc detachment voltage reduces re-striking of
the arc when moving the electrode away from the piece,
reducing spatter, burning and oxidisation of the piece.
If using electrodes that require high voltages, you are
advised to set a high threshold to prevent arc extinction
during welding.
Never set an arc detachment voltage higher than
the no-load voltage of the power source.
Parameter set in Volts (V).
Minimum 0V, Maximum 99.9V, Default 57V
500 Allows the selection of the required graphic interface:
Allows access to the higher set-up levels:
USER: user
SERV: service
vaBW: vaBW
551 Lock/unlock
Allows the locking of the panel controls and the inser-
tion of a protection code (consult the "Lock/unlock"
section).
601 Regulation step
Allows the regulation of a parameter with a step that can
be personalised by the operator.
Minimum 1, Maximum Imax, Default 1
602 External parameter CH1
Allows the management of external parameter 1 (mini-
mum value).
603 External parameter CH1
Allows the management of external parameter 1 (maxi-
mum value).
751 Current reading
Allow the real value of the welding current to be dis-
played.
Allows the welding current display method to be set.
752 Voltage reading
Allows the real value of the welding voltage to be dis-
played.
Allows the welding voltage display method to be set.
851 ARC-AIR enabling
On=ARC-AIR, Off=MMA
24
852 TIG DC LIFT START enabling
On=Active, Off=No active
854 Grinding enabling
Off = no active
0÷80V= grinding power supply
903 Program cancellation
Select the required program by rotating the encoder 1.
Delete the selected program by pressing button-encoder 2.
3.3 Lock/unlock
Allows all the settings to be locked from the control panel with
a security password.
"LOCK"
Enter set-up by pressing the encoder key for at least 5 seconds.
Select the required parameter (551).
Activate the regulation of the selected parameter by pressing the
encoder button.
Set a numerical code (password) by rotating the encoder.
Confirm the change made by pressing the encoder button.
"UNLOCK"
The carrying out of any operation on a locked control panel
causes a special screen to appear.
Access the panel functionalities by rotating the encoder and
entering the correct password.
3.4 Alarm codes
E01, E02 Temperature alarm
It is advisable not to switch off the equip-
ment while the alarm is on; the internal fan
will thus keep operating and will help to
cool the overheated parts.
E08 Blocked motor alarm
E10 Power module alarm
E13 Communication alarm
E19 System configuration alarm
E20 Memory fault alarm
E21 Data loss alarm
E40 System power supply alarm
E43 Coolant shortage alarm
E48 Wire out alarm
