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. Lifting instructions The power supply should be lifted by means of its lifting eye. The handle is only intended for pulling it along the ground. Connect the power supply lead using the appropriate fuse in conformance with local regulations. Cable areas acc. to Swedish regulations. Make sure the welding rectifier is not covered or positioned so that cooling is obstructed

9 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 voltage. 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 machine 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 regularly 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 S Disconnect the welding power source from the mains current supply. 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. ba11kyl a

10 WARNING! 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. 8 ORDERING OF SPARE PARTS LAX 320/320I/380/380W/380I/380WI is designed and tested in accordance with the EN (IEC ) international standard.
