Application classification
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 the welding power source.
Enclosure class
The IP code indicates the enclosure class, i. e. the degree of protection against penetration by solid
objects or water. Equipment marked IP 23 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.
The power supply should be lifted by means of its lifting
eye. The handle is only intended for pulling it along the
ground.
Lifting instructions
Connect the power supply lead using the appropriate fuse in conformance with local
regulations.
Cable areas acc. to Swedish regulations. Make sure the welding r ectifier is not cov-
ered or positioned so that cooling is obstructed.

A thermal cut--out prevents overheating. Resetting takes place automatically when
the power source has cooled.
The power sources can be equipped with instruments to display the current and vol -
tage. The instruments have a hold function and can be calibrated.
7 MAINTENANCE
Note:
All warranty undertakings given by the supplier cease to apply if the customer
attempts to rectify any faults on the m achine during the warranty period.
Only those persons who have appropriate electrical knowledge (authorised
personnel) may remove the safety plates to connect or carry out service,
maintenance or repair work on welding equipment.
Cleaning
Check r egularly that the power source is free from dirt.
How often, and to what extent, cleaning should be carried out depends on the
welding process, arc time, disposition and the surrounding environment. It will
normally suffice to blow the power source clean using compressed air (reduced
pressure) once a year.
If the power source is very dirty, brushing and vacuuming are recommended.
S Disconnect the welding power source from the mains current supply.
S Remove the adapter from the socket. Lock the socket to prevent unauthorised
connection.
At fixed installations, the safety switch should be set to the off position. Lock
the switch.
S Remove the power source’s safety plates for best access.
After cleaning, all safety plates must be mounted before you connect the power
source to the mains supply.
7.1 Topping up coolant
We recommend a 50/50 % mixture of water and ethylene glycol.

There is a risk of tipping if the wire feed cabinet is fitted with a counterbalance arm. Secure the
equipment, especially if used on an uneven or sloping surface.
Limit the angle of rotation of the wire feed cabinet using the straps supplied.
When moving the equipment, do NOT pull on the torch.
WARNING!
