Tig 3000i AC/DC
Operating temperature -- 1 0 t o + 4 0 ˚C
Constant A--weighted sound pressure <70 dB
Dimensions lxwxh 652 x 412 x 423 mm
Weight 42 kg
Insulation class transformer H
Enclosure class IP 23C
Application class
*) The minimum current during AC welding depends on the alloy used for the aluminium plates and
their surface cleanliness.
Duty cycle
The duty cycle refers to the time as a percentage of a ten--minute period that you can weld at a cer-
tain load without overloading.
Enclosure class
The IP code indicates the enclosure class, i. e. the degree of protection against penetration by solid
objects or water. Equipment marked IP23 is designed for indoor and outdoor use.
Application class
The symbol indicates that the power source is designed for use in areas with increased
electrical hazard.
5 INSTALLATION
The installation must be executed by a professional.
WARNING!
This product is intended for industrial use. In a domestic environment this product may cause radio
interference. It is the user’s responsibility to take adequate precautions.
5.1 Lifting instruction
5.2 Location

5.3 Mains power supply
Check that the welding power source is connected to the
correct mains power supply voltage, and that it is protected by
the correct fuse size. A protective earth connection must be
made in accordance with regulations.

Note! The mains cable areas and fuse sizes as shown above are in accordance with Swedish
regulations. Use the welding power source in accordance with the relevant national regulations.
Note! The welding power source is designed for connection to a 230 / 400 volt
system with four conductors.
If the power source is to be used in countries with a higher supply voltage, the power
source must be connected via a safety transformer.

6.3 Fan control
The power source has a time control that means that the fans continue to run for 6.5
minutes after welding has stopped, and the unit switches to energy--saving mode.
The fans start again when welding restarts.
The fans run at reduced speed for welding currents up to 110 A, and at full speed for
higher currents.
6.4 Overheating protection
The welding power source has overheating protection that operates if the
temperature becomes too high. When this occurs the welding current is interrupted
and a fault code is displayed on the control panel.
The overheating protection resets automatically when the temperature has fallen.

7 MAINTENANCE
Regular maintenance is important for safe, reliable operation.
Note!
All guarantee undertakings from the supplier cease to apply if the customer himself
attempts any work in the product during the guarantee period in order to rectify any
faults.
Maintenance must be executed by a professional.
Only those persons who have appropriate electrical knowledge (authorized
personnel) may remove the safety plates.
7.1 Inspection and cleaning
Power source
Check regularly that the welding power source is not clogged with dirt.
How often and which cleaning methods apply depend on: the welding process, arc
times, placement, and the surrounding environment. It is normally sufficient to blow
down the power source with dry compressed air (reduced pressure) once a year.
Clogged or blocked air inlets and outlets otherwise result in overheating.
Welding torch
The welding torch’s wear parts should be cleaned and replaced at regular intervals in
order to achieve trouble--free welding.
8 FAULT--TRACING
Try these recommended checks and inspections before sending for an authorised
service technician.
Type of fault Corrective action
No arc. SCheck that the mains power supply switch is turned on.
SCheck that the welding current supply and return cables are
correctly connected.
SCheck that the correct current value is set.
The welding current is
interrupted during welding.
SCheck whether the overheating protection has operated (fault
code E6 is displayed on the control panel).
SCheck the mains power supply fuses.
The overheating protection trips
frequently.
SMake sure that you are not exceeding the rated data for the
welding power source (i.e. that the unit is not being
overloaded).
Poor welding performance. SCheck that the welding current supply and return cables are
correctly connected.
SCheck that the correct current value is set.
SCheck that the correct electrodes are being used.
SCheck the mains power supply fuses.
