time ranges from 0.3 to 5 seconds.
8. SLd (Slop Down).
Possibility of adjusting from 0 to 10 seconds.
Defines the current slope down time from the welding
value to the arc shutdown
9. PrF (Pre-gas). Active in all MIG and TIG processes.
The adjustment may range from 0 to 10 seconds.
10. PoF (post-gas). Active in all MIG and TIG processes.
The adjustment may range from 0 to 30 seconds.
11. Acc (Soft Start). Active in all MIG processes. The
adjustment may range from 0 to 100%. It is the wire
speed, expressed as a percentage of the speed set for
the welding, before the wire touches the workpiece.
This adjustment is important in order to always achieve
good starts.
Manufacturer setting " Au" automatic.
The value can be changed using the knob L. If, once
changed, you wish to return to the original settings,
press the key E until the message "Au" reappears on
the display N.
12. BB (burn back). Active in all MIG processes. The
adjustment may range from 0 to 100%. Serves to adjust
the length of the wire leaving the contact tip after weld-
ing.
The higher the number, the more the wire burns.
Manufacturer setting " Au" automatic.
13. L (impedance). Active in all MIG processes. The
adjustment may range from -9.9 to +9.9. Zero is the
manufacturer's setting. If the number is negative the
impedance falls and the arc becomes harder; if it
increases the arc becomes softer.
14. ITO. (inching time out). Active in all MIG processes.
The purpose is to stop the welding machine if the wire
flows from the torch after starting with no passage of
current.
The wire output from the torch is adjustable from 5 to 50
centimeters using the knob L. Once the function has
been recalled it can be enabled(On) or off (Off).
15. H2O (Cooling unit). Active in all MIG and TIG
processes. Turning the knob L selects the type of opera-
tion: OFF = off, On C = always on, On A = automatic
start-up. When the machine starts, the unit is running.
If the torch trigger is not pressed, it shuts off after 15
seconds.
When the torch button is pressed, the unit begins oper-
ating, and shuts off 3 minutes after the button itself is
released.
If the coolant pressure is too low, the power source
delivers no current and the display O will show the mes-
sage H2O, flashing.
16. Fac. (factory). The purpose is to return the welding
machine to the original settings provided by the manu-
facturer.
With the function selected, the display N shows, noP =
returns the welding machine to the originally supplied
settings without affecting the saved programs, Prg =
deletes all saved programs, and ALL = returns the weld-
ing machine to its originally supplied settings.
To confirm the desired function simply press the button
E for 5 seconds. The abbreviation shown on the display
N will begin to flash, and after a few seconds a sound
will confirm that it has been saved.
4 INSTALLATION
The welding machine must be installed by skilled person-
nel. All connections must be made in full compliance with
current safety laws.
4.1 PLACEMENT
The weight of the welding machine is 110 Kg, thus for lift-
ing see Fig. 3
Fig. 3
Position the equipment in an area that ensures good sta-
bility, efficient ventilation so as to prevent metal dust (i.e.,
from grinding) from entering.
4.2 SETUP
Position the wire feeder on the power source.
Connect the wire feeder to the power source via the con-
nection art. 1178 or 1178-20, using the plate provided to
fasten it on the trolley shelf.
NOTE: avoid coiling the connection to reduce to a mini-
mum the inductive effects that could affect the results in
sinergyc MIG/MAG welding.
Mount the plug on the power cord, being especially care-
fully to connect the yellow/green conductor to the earth
pole.
Make sure that the supply voltage corresponds to the
rated voltage of the welding machine.
Size the protective fuses based on the data listed on the
