EN3.6 autOmatiC wire Feed tO gunAutomatic wire feed makes change of wire reel more rapid. In reel change the pressure of feedrolls need not to be released and filler wire goes automatically to correct wire line.• Make sure that groove of feed roll matches the diameter of welding wire used. Feed rollgroove is selected by moving the groove selecting washer. Also the selector plate forchanging the feed roll groove has to be moved similarly. (see tables on pages 6 and 7).Groove selecting washer• Release the wire end from reel and cut off the bent length. Be careful that the wire doesnot spill from the reel to sides!• Straighten about 20 cm of the wire and see that the end of it has no sharp edges (fileoff if necessary). A sharp edge may damage the wire guide tube and contact tip of thewelding gun.• Draw a bit of loose wire from wire reel. Feed wire through back liner to feed rolls. Don´trelease pressure of feed rolls!• Press the gun switch and feed a bit wire until wire goes through feed rolls to gun. Seethat wire is in grooves of both feed roll pairs!• Press still the gun switch until wire has come through contact tip.Automatic feed may sometimes fail with thin wires (Fe, Ss: 0.6 ... 0.8 mm, Al, Fc: 0.8 ... 1.0 mm).Then it might be possible that you must open feed rolls and feed wire manually through feedrolls.adjustment of pressureAdjust the pressure of feed rolls with the control screw (20) so that the wire is fed into the wireguide tube evenly and allows a little braking when coming out from the contact tip withoutslipping at the feed rolls.NOTE! Excessive pressure causes flattening of the filler wire and damage to the coating. It alsocauses undue wear of the feed rolls as well as friction.3.7 adjustment OF tightness OF wire reel braKeBrake force is adjusted through hole in locking device of reel hub by screwing the controlscrew with screwdriver.Adjust brake force as so big that the wire cannot spill from the reel when the rotation of thereel stops. Need for brake force is increased with increase of the wire feed speed.Since the brake loads for its part the motor, you shouldn´t keep it unnecessarily tight.Adjustment screw10Kempomat 2500, 3200, 4200 / © Kemppi Oy / 1117
