MACHINE PROGRAMME

NAVIGATOR 2500/3000 is a line of welding machines,
especially designed for welding in e.g. the sheet metal
and tube industries.
There are several versions of the machine: MMA, TIG
DC and TIG AC/DC. DC stands for welding with direct
current. AC stands for welding with alternating current.
All versions are designed for welding with coated
electrodes and are equipped with antifreeze, adjust-
able arc power and hot-start. Moreover, the machine
can be used for pulse welding with the possibility of
setting of pulse time, pause time and base amp.
In TIG welding the following functions are included:
- adjustable slope up and slope-down
- adjustable gas pre-flow and gas post-flow time
- adjustable start Amp and stop Amp
- adjustable reduced current
- choice of 2-times-, 4-times- and spot welding
- LIFTIG
- HF-TIG
- connection and disconnection of pilot arc
- AC-balance
- AC welding frequency
- digital display
- current control from the TIG torch handle
- remote control facility (option)
- programming of up to ten welding settings
In LIFTIG ignition the TIG arc is ignited after making
contact between the workpiece and the tungsten
electrode, after which the trigger is activated and the
arc established by lifting the electrode away from the
workpiece.
In HF-TIG ignition the TIG arc is ignited without con-
tact. A high-frequency (HF) impulse initiates the arc
when the trigger is activated.
Transportation equipment
The MIGATRONIC programme includes a transport
trolley which can be used for all versions.
Welding hoses
The machine can be equipped with TIG welding
hoses, electrode holders and return current cables
from the MIGATRONIC programme. If an adjustable
TIG torch is used, the welding current can be adjusted
from the torch.
External adjustment (option)
Remote control and foot control units can be delivered
to NAVIGATOR 2500/ 3000.
Torch cooling module (option)
An integrated torch cooling module can be delivered
which enables use of watercooled TIG welding torches
from the MIGATRONIC programme.

Configuration
MIGATRONIC disclaims all responsibility for damaged
cables and other damages related to welding with
undersized welding
measured by welding specifications e.g. in relation to
permissible load.
Important!
In order to avoid damage to plugs
and cables, good electric contact is
required when connecting the work
return cable and welding torch to the
machine.
Warning
Connection to generators can damage the welding
machine.
When connected to a welding machine, generators
can produce large voltage pulses, which can damage
the welding machine. Use only frequency and voltage
stable generators of the asynchronous type.
Defects on the welding machine arisen due to
connection of a generator are not included in the
guarantee.
Mains connection
NAVIGATOR 2500/3000 is designed for connection to
the mains voltage mentioned on the type plate. After
the mains plug has been connected to the mains cable
(6) the machine is ready for use. Please note that all
cable connections must be made by authorised and
qualified staff. Switch on and off the machine by
means of the breaker on the rear of the machine (5).
Gas connection
Connect the machine to the gas system by means of a
gas flow control.
