Important!
In order to avoid destruction of plugs
and cables, good electric contact is
required when connecting earth cable
and welding torch to the machine.
Connection of shielding gas
The shielding gas hose is fitted to the back panel of
the power source (3) and is connected to a gas supply
with a pressure reducton to 2-6 bar (with a gas
adjustment kit mounted). A gas cylinder can be
mounted on the bottle carrier on the back of the trolley.
Adjustment of wire brake
The wire brake must ensure that the wire reel brakes
sufficiently quickly when welding stops. The required
brake force is depending on the weight of the wire reel
and the maximum wire feed speed. A brake torque of
1.5-2.0 Nm will be satisfactory for most applications.
Adjustment:
- Dismount the control knob by
placing a thin screw driver behind
the knob and thereafter pull it out
- Adjust the wire
fastening or loosening the self-
locking nut on the axle of the wire
hub
- Remount the knob by pressing it
back into the groove
Connection of a cooling unit
Fastened the module under the power source. Mount
the 4-poled plug (9) in the corresponding socket in the
power source (10). Mount the flow hose in the quick
connection marked with blue and the return hose in
the quick connection marked with red. The cooling
liquid level can be seen in the inspection cover frame
(13).
Filling of cooling liquid
The cooling unit can be filled up with cooling liquid
through the outer filler neck (14).

The following parts must be used when changing the
Flex 3000 C from an air-cooled into a water-cooled
machine:
Cooling unit
Loading of MigaCARD
The delivered MigaCARD should be placed in the
MigaCARD reader in the wire panel (description of
wire panel page 23). The LED will be switched on
when the card is placed correctly and loading of the
machine software and the welding programs is
started.
It is recommendable to remove the card form the
MigaCARD reader if the card is editable. If the card
remains in the MigaCARD reader, all user settings will
be overwritten to standard setting when the machine is
restarted.
Important!
The machine cannot weld at delivery. Data at
MigaCARD must be loaded in the machine before
use.
Trolley with automatic mains voltage transition
(Special equipment)
The machine can be delivered with a trolley with a
unit, which automatically adjust the actual mains
voltage on the working area. With this transition unit
the machine can be connected to 3*230V, 3*400V,
3*440V, and 3*500V.
The auto-transformer has a
mains switch (16), which can
connect and disconnect the
mains supply. Moreover, the
unit has a standby function.
The auto-transformer enters
sleeping mode and the supply
voltage is disconnected to the
welding unit, when the auto-
transformer has not been used
for 40 minutes.
The autotransformer can be switched on again by
pressing the key pad (17) on the auto-transformer unit.
The standby function can be permantly disconnected
by a technician when requested.
