8 GB 2 INTRODUCTION 2.1 General LAF 1250 is a remote--controlled 3--phase welding power source designed for high--efficiency mechanical gas metal arc welding (MIG/MAG) or sub arc welding (AW). It is always to be used in combination with EAB s control box A2--A6 Process Controller (PEH). LAF is fan--cooled and monitored by a thermal overload protection. When the protection enters into action a yellow indicating lamp on the front panel goes on and is reset automatically as soon as the temperature has gone down to an acceptable level. The welding power source and the control unit are linked together over a 2--wire bus enabling precision control of the welding process. All welding parameter settings for the power source can be made by the operator on the front panel of the control unit. The operation of the power source is completely controlled and monitored by this unit. Even the start and stop qualities can be set by way of the control unit. The preset welding current parameters can also be monitored in the course of welding. For more detailed information regarding the settings and the working mode of the welding power source, please refer to the instruction manual for the A2--A6 Process Controller. 2.2 Technical data Voltage Permissible load at: LAF /415/500 V, 3µ50 Hz 400/440/550 V, 3µ60 Hz 100 % duty cycle 1250 A/ 44 V etting range MIG/MAG AW No -load voltage No -load power 60 A/ 17 V A/ 44 V 40 A/ 22 V A / 44 V 51 V 220 W Effiency 0,87 Power factor 0,92 Weight 490 kg Dimensions L x W x H 774 x 598 x 1430 Class of enclosure IP 23 Class of application 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. fja3d1ea

9 GB 3 INTALLATION 3.1 General The installation must be executed by a professional. 3.2 Unpacking and erection WARNING - TIPPING RIK! Fasten the equipment -- particularly if the ground is uneven or sloping. Place the welding power source on a level foundation. Make sure there is nothing to prevent the cooling. Lifting instructions 3.3 Connections On delivery the welding power source is connected for 400 V. For other supply voltage, switch over to the desired voltage on the main transformer and the control transformer according to the connection instructions on page 108. Make sure the mains cable has the right sectional area and fuse it with an adequate fuse according to applicable local directions (see table on page 42). Connect the earth cable to the screw marked. Tighten the cable support (1). Connect the mains cable to the main terminal blocks L1, L2 and L3. Connect the control cable between the LAF welding power source and the control unit to the 28--pole contact (2) inside the welding power source. Connect 1 pin socket measure cable (4). Connect a suitable welding and return cable to the contacts (3) marked + and - on the front of the power source. fja3i1ea

11 GB 4 OPERATION 4.1 General General safety regulations for the handling of the equipment can be found on page 38. Read through before you start using the equipment! 4.2 Controls The front panel contains: 1. Main switch, breaking the incoming mains voltage for the welding power source. 2. Indicating lamp (white), showing that the main switch is activated. 3. Indicating lamp (yellow), showing that the thermal protection has entered into action due to overheating in the transformer. The lamp is reset when the temperature has gone down to an acceptable level. 4. Pushbutton, for the resetting of automatic fuse FU2 for 42 V supply voltage. 4.3 tart -up Connect the return cable to the work piece. et the main switch (1) to position I. The white indicating lamp (2) goes on and the fan starts. et the welding parameters and start welding by way of the control box (see instruction manual xxx for A2--A6 Process Controller). fja3o1ea

12 GB 5 MAINTENANCE 5.1 General 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. 5.2 Cleaning Clean the welding power source as necessary.
