this function influences the size of the „ball“at the end of welding wire and so the qualityof further lighting-up the arc. It is requiredto adjust parameters of combustion so thatthe ball at the end of wire was as small aspossible. Parameters differ according to differentwelding materials.ADJUSTMENT OF SOFT STARTThis function enables when suitably adjustedlighting-up of the arch without anyproblems and no unnecessary spatter and„movement“ of the welding torch. Weldingwire is after pressing the button of the weldingtorch shifted at a small approachingspeed adjusted by potentiometer SOFTSTART (picture 4). At the time of the contactof welding wire and material, arc islighted-up and there is an automatic switch-ing to the shift value adjusted with the potentiometeron panel inside of the wirefeeder (picture 1, position 5) – so calledSOFT START.Picture 42. Adjust the PROCESS switch (pos.6 and7 pict. 1) to the most suitable positionaccording to the type of welding to becarried out.3. Turn on the welder by selecting pos. 1on the supply switch (pos. 1 pict. 1).MaintenanceWarning: Before carrying out any inspectionof the inside of the generator, disconnectthe system from the supply.SPARE PARTSOriginal spare parts have been specially designedfor our equipment. The use of nonoriginalspare parts may cause variations inperformance or reduce the foreseen level ofsafety.We decline all responsibility for the use ofnon-original spare parts.THE GENERATORAs these systems are completely static, proceedas follows:• Periodic removal of accumulated dirtand dust from the inside of the generator,using compressed air. Do not aimthe air jet directly onto the electricalcomponents, in order to avoid damagingthem.• Make periodical inspections in order toindividuate worn cables or loose connectionsthat are the cause of overheating.• Periodical revision inspection of themachines has to be done once in a halfof year by an authorised staff in accordwith CSN 331500, 1990 and CSN056030, 1993.and the whole weld against the effects ofsurrounding atmosphere (pic. 3).ADJUSTMENT OF WELDING PARA-METERS OF VOLTAGE AND SPEEDWIREAdjustment of main welding parameters ofwelding voltage and speed of wire shift iscarried out with a potenciometer of wirespeed (picture A position 1) and a voltageswitch (picture 1 position 1). You shall alwaysallocate speed of wire shift to adjustedvoltage (switch position 1-20). Adjusted parametersdepend on used protective gas,wire diameter, applied wire type, size andposition of a weld etc. Reference setting ofwire speed and switch positions can befound in page 43 - 48.For instance:Welding machine KIT 255, used protectivegas MIX (82% Argon and 18% CO 2 ) andused wire diameter 0,8mm can be found in achart (program No). Adjusted values will bethen – Switch position A1 and adjustedspeed of wire shift will be 2 m/min.MACHINES PROCESSOR ANDSYNERGICSetting speed of wire shiftPress button SET until you switch on LEDdiode marked in the picture.ther a potenciometer or a remote controlUP/DOWN can be used. During welding(turning the potenciometer).NOTE 2: Bottom display shows speed ofwire shift only if red LED diode is on SET-TING and LED diode m/min.ADJUSTMENT OF OTHER WELDINGPARAMETERSControlling electronics of machines Processorand Synergic enables adjustment of thefollowing welding parameters:• Time duration of gas fore-blow 0-5 sec.(time of protective gas fore-blow beforethe beginning of welding process).• Time of start of wire shift speed (functionSOFTSTART) 0-5 sec. (time ofstart from minimum shift speed up tovalue of adjusted welding wire speed).• Speed of wire shift m/min (speed ofwire shift during welding).• Time of switching off interval of weldingvoltage on arc opposite wire shift:„burning out“ of wire towards the torchtop.• Time of gas afterblow after finishingwelding process 0-5 sec.Setting gas fore-blowPress button SET until you switch on LEDdiode marked in the picture.Prior to weldingIMPORTANT: before switching on thewelder, check once again that the voltageand frequency of the power network correspondto the rating plate.1. Adjust the welding voltage using theswitch (pos. 2,4 pict. 1) and weldingcurrent/wire speed using the panel potentiometer(pos. 5 pict. 1).WIRE FEEDGreat attention has to be paid to the feedingmechanism, especially to the sheaves andthe space around them. During the wirefeeding, copper coating peels off and smallfillings fall off, which are either broughtinto the spring or pollute the inner space offeeding mechanism. Regularly remove andstore up dirt and dust from the inner part ofwire store and feeding mechanism.Use the potenciometer to set up requiredvalue of shift speed within range 0,5-20m/min.NOTE 1: Speed of wire shift can also beadjusted and changed during welding. Ei-Use the potenciometer to set up requiredvalue of gas fore-blow time within range0-5 sec.ADJUSTMENT OF THE START OFWIRE SPEED – THE FUNCTIONSOFT-START- 40 -- 33 -
