EN2.5 OperatiOn and use OF COntrOlsSee the page for Kempoweld PANELS and COOLING UNIT.2.5.1 main switch (s1)In zero position all control and welding current circuits of the equipment are dead (withoutvoltage). In position I the control circuits of the machine become live (get voltage). Theprimary and welding circuits are dead, if the welding mode has not been started with the guntrigger.NOTE! Always switch on and switch off the machine from the main switch. Never use the mainsplug for switching on or switching off the units and equipment!2.5.2 adjustment of welding voltage,table of adjustments, switch positions:coarse control fine control open circuit voltage1 / 4 1 / 10 – 10 / 10 15.5 – 18.2 V2 / 4 1 / 10 – 10 / 10 18.6 – 22.5 V3 / 4 1 / 10 – 10 / 10 23.1 – 29.3 V4 / 4 1 / 10 – 10 / 10 30.4 – 41.6 VThe welding voltage is adjusted with two turn switches. The S2 is the 4-step switch for coarsecontrol, where voltage value of each step can be fine-adjusted with the 10-step switch S3.2.5.3 pilot lampspilot lamps of the machine report about electric function:The green pilot lamp H1 indicating that the machine is ready for operation is always lit, whenthe machine is connected to mains voltage and the main switch is on position I.The yellow pilot lamp H2 is lit, when thermal protection of the welding circuit has releaseddue to overheating. The protection releases if the power source is continuously loaded overrated values or the cooling air circulation has been obstructed.2.5.4 Control fuse (F1)On the rear plate of the power source the fuse (F1) 8 A delayed is the short-circuit protection.Use the fuse size and type according to markings. Damage caused by a wrong type fuse is notcovered by the guarantee. If the fuse is blowing again, send the unit to service.2.5.5 adjustment for arc roughnessArc roughness is adjusted by connecting the return current cable to the applicable one of thetwo dix-connectors on the front plate.The connector marked with shorter symbol gives a rougher arc, which is used for weldingof thin sheets and ferrous metals by 0.6 – 1.0 mm wires and especially with CO² shieldinggas. The connector marked with longer symbol is suitable for thicker wires and especially foraluminium and stainless materials. The most suitable roughness is, however, most dependenton the welding case. You will find the best position by testing the different positions.2.5.6 Operation of cooling fanThe cooling fan on the rear plate of the Kempoweld 3200 equipment is started and stoppedaccording to use. The cooling fan is controlled by the gun trigger and control circuits. Thecooling fan is started after ca. 15 s after weld start and stopped after ca. 10 min after weld endor release of the overheat protection.NOTE! Do not switch off the unit with the main switch before the cooling fan has automaticallystopped. By open circuit the cooling fan does not get started.9Kempoweld 3200, 3200W / © Kemppi Oy / 1117
