Fronius CMT 4000 Advanced User Manual

NOTE!
External enabling of the spatter-free ignition option is possible from firmware ver-
sion OFFICIAL UST V2.70.1 (power source) upwards. At present, this option only
supports aluminium wires of diameters:
▶
0.8 mm / 1.0 mm / 1.2 mm / 1.6 mm
▶
USA: 0.9 mm (0.035 in.) / 1.2 mm (0.045 in) / 1.6 mm (1/16 in.)
NOTE!
Not all of the stored welding programs support the SFI function.
SFI is automatically deactivated on changing to a welding program that does not support
the SFI function.
SFI must be re-activated on changing back to a program that supports the SFI function.
More information about whether a welding program supports SFI can be found on the
sticker with the program chart on the power source.
The SFI function is set in the Process setup menu (Fdc parameter).
SynchroPulse
option
The SynchroPulse option is recommended for welding aluminium alloys where you want
to give the weld seams a rippled appearance. This effect is achieved by having the weld-
ing power alternate between two operating points.
The two operating points result from the welding output being changed - positively and
negatively - by an adjustable dFd value that can be set in the Setup menu (welding
power offset: 0.0 - 2.0 m/min or 0.0 - 78.74 ipm).
Additional parameters for SynchroPulse:
- Frequency F for alternating between operating points (set in the Setup menu)
- Arc length correction for the lower operating point (set using the arc length correc-
tion parameter on the control panel)
- Arc length correction for the higher operating point (set in the Setup menu, para-
meter Al.2)
In order to activate SynchroPulse, you must (as a minimum) change the value of the
parameter F (frequency) in the Process setup menu from OFF to between 0.5 and 5 Hz.
System requirements:
- Firmware version on the power source: OFFICIAL UST V2.60.4
- Firmware version on the wire-feed unit: OFFICIAL SR 1 V1.40.15
NOTE!
External enabling of the SynchroPulse option is possible from firmware version
OFFICIAL UST V2.70.1 (power source) upwards. Only Fronius push-pull wire-feed
unit systems are supported.
NOTE!
As long as the Standard manual welding process is selected, the SynchroPulse
option is not supported.
