Duty cycle
The duty cycle refers to the time as a percentage of a ten-minute period that you can weld at a
certain load without overloading.
Enclosure class
The IP code indicates enclosure class, i.e. the degree of protection against penetration by solid
objects and 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.

5.1 Placing
Place the machine so that there is nothing to prevent the cooling air from passing
through it (air being drawn into the machine through a grill on the back).
5.2 Lifting instructions
5.3 Mains power supply
• Check that the welding power source is connected for the available mains power
supply before connecting it to the mains.
• The mains cable is connected to the connection block XT1 (using terminals L1,
L2 and L3) and PE-terminal.
• Make sure that the connection blocks XT1 and XT2 are correctly wired for the
mains voltage used. (When delivered welding power source is wired for the
mains voltage 3x400-415V, 50Hz).
• Connect the mains cable to the mains power supply according to the relevant
regulations and install appropriate fuses in the main fuse box.

6 OPERATION
General safety regulations for the handling of the equipment can be found on
page 36. Read through before you start using the equipment!
6.1 Start-up
• Start the welding power source by setting the mains switch to position “I”. The
white lamp will light up and the fan will be started.
• Set the welding current, using the crank on the front. The selected welding
current is shown by the dial. Follow the instructions on the electrode package for
the recommended welding current.
• Connect welding and return cables to the terminals marked + and - on the front
of the power source. Polarity reversal is carried out by changing over the welding
and return cable connections. Connect return cable to the work piece.
• The power source is now ready for welding.
6.2 Overload protection
The thermostat prevents overheating of the welding power source. The yellow LED
lights up in case of overheating. Resetting takes place automatically as soon as the
power source has cooled down.
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.

GB
7.1 Inspection and cleaning
Normally it is sufficient to blow the welding power source clean regularly using dry
compressed air at reduced pressure. In dusty and dirty environment the welding power
source should be cleaned at shorter intervals.
Where necessary, lubricate the chain and sprocket using heat-resistant grease. When
required, the gliding surfaces of the leakage cores can also be smeared with a thin
coating of this grease.
8 FAULT TRACING
Try these recommended checks and inspections before sending for an authorised
service technician.
Type of fault Measure
No arc. • Make sure the mains switch is on.
• Check that the welding and return
cables are properly connected.
• Make sure the welding current setting is
correct.
The welding current is interrupted in the
course of welding.
• Check if the thermal cut-out has tripped
(the yellow indicating led on the front
panel is on).
• Check the mains power supply fuses.
The thermal cut-out trips frequently. • Check that the ratings of the welding
power source have not been exceeded
(overload of the power source).
Poor welding result. • Check that the welding and return
cables are properly connected.
• Make sure the welding current setting is
correct.
• Check that the correct electrodes are
being used.
