Keep your head out of the fumes.
Use ventilation, extraction at the arc, or both, to take fumes and gases away from your breathing zone
and the general area.
ARC RAYS - Can injure eyes and burn skin.
Protect your eyes and body. Use the correct welding screen and filter lens and wear protective
clothing.
Protect bystanders with suitable screens or curtains.
FIRE HAZARD
Sparks (spatter) can cause fire. Make sure therefore that there are no inflammable materials nearby.
NOISE - Excessive noise can damage hearing
Protect your ears. Use earmuffs or other hearing protection.
Warn bystanders of the risk.
MALFUNCTION - Call for expert assistance in the event of malfunction.
PROTECT YOURSELF AND OTHERS!

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 or cut at
a certain load without overloading. The duty cycle is valid for 40°C.
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.
Mains supply, Ssc min
Minimum short circuit power on the network in accordance with IEC 61000-3-12
4 INSTALLATION
The installation must be executed by a professional.
Note
Mains supply requirements
High power equipment may, due to the primary current drawn from the mains supply, influence the
power quality of the grid. Therefore connection restrictions or requirements regarding the
maximum permissible mains impedance or the required minimum supply capacity at the interface
point to the public grid may apply for some types of equipment (see technical data). In this case it
is the responsibility of the installer or user of the equipment to ensure, by consultation with the
distrubution network operator if necessary, that the equipment may be connected.

5.3 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.
5.4 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.
6 MAINTENANCE
Regular maintenance is important for safe, reliable operation.
CAUTION
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.
Only those persons who have appropriate electrical knowledge (authorized
personnel) may remove the safety plates.
6.1 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.
