Connection of electrode holder for MMA electrode
welding
The electrode holder lead and the return lead are
connected to the positive (13) and negative (14) poles
respectively for most applications. The actual choice of
polarity is recommended on the electrode packet.
Connection of a cooling unit
Fastened the module under the power source. Mount the
4-poled plug (27) in the corresponding socket in the
power source (20). Mount the flow hose on the water
cooled torch in the quick connection marked with blue (3)
and the return hose in the quick connection marked with
red (4). The cooling liquid level can be seen in the
inspection cover frame (26).
Note: O-ring on the stopper to the filler neck must be
removed before starting up of the cooling unit.
Filling with cooling liquid
Cooling liquid can be filled into the torch cooling unit by
opening the cover (23), pulling out the water tank and
dismounting the screw plug (24). The drain plug for filling
up (31) should be loosened.
The cooling unit should be filled up at maximum. In case
of problems when starting up, the drain plug (30) should
be opened. Close the drain plug when the system has
been drained.
Refillment of cooling liquid should be carried out behind
the front cover (23) (pull out the drawer in order to make
the filler neck accessible).
Connecting the remote control
A remote control can be connected to the machine by
screwing the plug onto the 8-pole plug (15). The plug is
fixed by screwing on the cap.
Fitting of overlay foil
It is recommended to install the included overlay foil and
inset card after basic setting of the machine. The working
plans chosen by the manufacturer are printed on the front
of the inset card.
In case of changes in the choice of working plans, their
main parametres can be added to the reverse side of the
inset card.
Overlay foil is designed to partially cover the secondary
settings on the XMI boxes 76113650 and 76113655.
Diagram no. 61113665 is used for
the electronic control units:
- 76113650 software version from 1.03
- 76113655 software version from 3.01
Diagram no. 61113728 is used for
the electronic control units:
- 76113659 software version from 1.00
Diagram no. 61113721 is used for
the electronic control units:
- 76113658 software version from 1.00
The overlay foil is fastened under the top screws for the
electronic control unit (fig. 3 page 95). If required, the foil
can also be fastened with tape along the bottom edge
(remove the paper strip). After installation of the overlay
foil there is no access to parametre curve and change of
the secondary functions. However, the most frequently
used functions during operation can still be operated in a
If change of the secondary parametres is
normal way.
required, the overlay foil can be removed and fitted
again after setting.
Trolley with Automatic
voltage transformation module
FLEX MFA 400
Description of the automatic
voltage transformation module
Trolley for 2 bottles and equipped with an automatic
voltage transformation module enables connection with
the power source to the following mains voltages: 230-
400-440-500V.
The module automatically measures the mains voltage
and makes the necessary voltage transformation to
supply the power source. The module has a mains switch
(8). If the power down mode is enabled on the control
PCB (13) the module will automatically activate power
down after 40 min. without use of the welding power
source. When pushing the control knob (7) on the front,
the module will power up again. (Circuit diagram page
97).
We recommend use of the slope down function during
welding with large currents. Otherwise, transients that
decouple the machine may arise when the machine is
equipped with automatic change of voltage and
connected to 230V.
