NERTAMATIC 450 AC/DC -5
NERTAMATIC 450 is a source for supplying power to TIG or
plasma welding torches from the mains.
3-phase power
supply + ground 230 V 400 V 415 440 V
Maximum intensity 54.9 A 32.2 A 31 A 29.8 A
Fuse size 60A 40A 40A 40A
Section of the power
supply cable 10mm² / phase 6mm² / phase 6mm² / phase 6mm² / phase
This power source is a power supply where the intensity is imposed at all times. The
system stability relies on an electronic current regulation system that can react at the speed
of the arc.
It is cooled by a forced ventilation system. Filters placed on the air inlets extend the life
of the components of the power source when it is used in dusty environments.
The cooling air is taken in through openings in the side panels and the upper front door
and then transferred to the rear by means of a fan.
NERTAMATIC 450 has several auxiliary power supply systems, which are alternative low-
voltage sources that power the cycle box, the AVC, the wire feeding funcion, the BRT, some
movements etc.
It offers an internal visualisation of its operating status and a galvanised insulated interface
for dialogue with the “outside”.

2 – INSTALLATION
A) UNPACKING - HANDLING
1) Unpacking 2) Handling
Cut the box straps. You can now install the power supply either :
Remove the cover plate and protective cover
(cardboard). - with a fork lift truck or a pallet truck,
Disunite the power supply from the pallet (8 mm
nuts). - or using the 2 slinging rings intended for that purpose with a crane or a lifting bridge.
Operator's protection:
Helmet - Gloves - Safety
shoes

3) Location of the current source (power source):
For optimised operation and a longer life, the
power source location should be selected
carefully. The device should not be installed in
places exposed to humidity, high temperature
or corrosive fumes. Leave clearance of 500
mm around the sides and rear of the unit.
Make sure that the fan openings are not
blocked. Air enters into the machine through
the front and the sides.

2 – INSTALLATION
-8 NERTAMATIC 450 AC/DC
B) CONNECTION
The installation is wired for a 400V mains
voltage.
If the power supply voltage is 230V, 415V or 440V, the
transformers inside the power source must be rewired
accordingly.
Primary cable Primary + auxiliary wiring
CONNECTING NERTAMATIC 450
Remove the right side panel (10 mm key).
Wire the main transformer and the auxiliaries by means of terminal plates
PAB1, PAB2 and PAB3, depending on the local supply voltage. The unit is
supplied wired for 440V. DO NOT FORGET THE AUXILIARY WIRING
(PAB3).
Connect the power supply cable to the terminal plate (right-hand side of
the contactor).

4 - MAINTENANCE
A - SERVICING
So that the machine continues to provide good service for as long as possible, a certain minimum of care and
maintenance is necessary
The frequency of this maintenance work is given on the basis of the production of one work station per day.
Maintenance should be more frequent if production is greater.
Your maintenance department may photocopy these pages so that it can follow up maintenance dates and
operations (tick as appropriate)
every 40 hours
- Check if the air filters are dirty, clean them or change them.
NOTE: use a vacuum nozzle to clean the power source
