Application classefication
These welding power sources conform to the requirements of IEC 974--1.
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 I NSTALLATION
The in stallatio n must b e executed by a professional.
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
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.
IMPORTANT
S Place the welding power source in a suitable place and make sure the welding
rectifier is not covered or set--up so that cooling is prevented.
S Make sure the welding rectifier is connected to the correct mains voltage.
Earth according to applicable directives.
S Connect the power supply lead using the appropriate fuse in conformance with
local regulations.
Power supply lead complies to Swedish electrical regulations.

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!
7 MAINTENANCE
Note:
All warranty undertakings given b y the supplier cease to apply if the customer
attempts to rectify any faults on the machine during the warranty period.
The power source should be regularly blown clean using dry compressed air at
reduced pressure. More frequently in dirty environments.
Otherwise the air inlet/outlet may become blocked and cause overheating.
7.1 Topping up coolant
Mix: 50 % water 50 % glycol
8 ORDERING OF SPARE PAR TS
Spare parts are ordered through your nearest ESAB representative, see back cover.
When ordering spare parts, please state machine type and number as well as desig -
nation and spare part number as shown in the spare parts list.
