EN2.5.7 accessory drawerIn the accessory drawer in the cover part of the unit are by delivery the plastic guide tubesneeded for welding of aluminium and stainless steels. In the drawer are also the screw and theinsulation bushings needed for locking of rotation of the wire feeder Kempoweld WIRE 400.2.5.8 adjustment for wire feedThe wire feed is adjusted from the potentiometer on the control panel of the wire feeder unitKempoweld WIRE 400. The adjustment has been described in the operation instructions of thewire feeder unit.2.6 VOlt / ampere metering unit msd-1For the mounting of the MSD-1 remove the cover plate on the front panel of the unit.The connector of flat cable fastened to the cover plate is connected to the correspondingconnector of the MSD-1. From the metering unit you can with lever switch select momentarydisplay for either voltage or current. By open circuit only voltage value is displayed, becausethere is no welding current present.The voltage value is the voltage between the unit´s welding connectors or terminal voltage.The value of the open circuit voltage has not very much importance for the welding, so thatthe display of the metering unit is adjusted according to the welding situation. The displayof the open circuit voltage differs 2 – 3 V from the true voltage. During welding the terminalvoltage is varying and the arc voltage differs from the terminal voltage due to cable etc. losses.Accuracy of voltage true value in respect to real value is ±4,0 %, ±0,2 V by welding valuesaccording to the norm.Accuracy of current true value in respect to real value is ±2,5 %, ±2 A.The metering unit does not show wire feed values.The MSD-1 does not need any calibration in the Kempoweld power source.The switch positions: V = voltage display, A = current display.2.7 COOling unitKempoweld 3200W power source has inbuilt cooling unit.2.7.1 installation of coolingThe cooling unit is connected to the gun by means of water hoses, which are mounted to thewire feeder unit. The interconnection cable contains also the water hoses, which are mountedto the gun through the wire feeder unit without any extension parts. See operation instructionfor Kempoweld WIRE feeders.Before connection check that in the hoses are no dirt, metal powder, rubber waste etc. Theconnectors for hoses and cooling unit are marked with red or blue identification rings orspots. Blue is colour for water supplied from cooling unit to gun and red is colour for waterreturning back from gun to cooling unit.The cooling unit´s tank is filled with 40 % antifreeze according to British Standard BS3151. Ifthe circumstances do not require frost resistance, you can use a more dilute mixture, or someother mixture, of which you have good experriences.Tank volume is ca. 3 litres, volume of gun and interconnection cable is 0.3 – 1.5 litres. Filling ofhoses takes 5 s – 3 min time. Check the return flow to the tank. Before filling check that tank,cooling water, pouring tank etc. are clean, and that there is no metal powder, waste etc.10Kempoweld 3200, 3200W / © Kemppi Oy / 1117
