INSTALLATION OF wELDING GUNMake sure the gun wire conduit and the contact tip match the manufacturer’s recommendationsfor the type and diameter of wire you use. Too small a conduit may overload the wire feed deviceand impede the wire feeding. Tighten the gun’s quick connector to eliminate voltage loss. A loosejoint will heat up the gun and wire heater.Never use defected gun.2.7. MOUNTING AND LOCkING OF wIRE REEL– Release locking nails of wire reel hub by turning locking knob a quarter round.– Mount the reel at its place. Note rotating direction of reel!– Lock the reel with locking knob, locking nails of hub remain to outside position and willlock the reel..2.8. 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.– Release the wire end from reel and cut off the bent length. Be careful that the wire does notspill from the reel to sides!– Straighten about 20 cm of the wire and see that the end of it has no sharp edges (file off ifnecessary). A sharp edge may damage the wire guide tube and contact tip of the weldinggun.– Draw a bit of loose wire from wire reel. Feed wire through back liner to feed rolls. Do notrelease pressure of feed rolls!– Press the gun switch and feed a bit wire until wire goes through feed rolls to gun. See thatwire 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, Fc, Ss: 0,6...0,8 mm, Al: 0,8...1,0 mm). Inthat case you might have to open feed rolls and feed wire manually through feed rolls.Note! Check that the wire or wire reel does not touch the equipment body, there isa danger of short circuit!2.9. ADjUSTMENT OF PRESSUREAdjust the pressure of the feed rolls with the control screw so that the wire is fed into the wireguide tube evenly and allows a little braking when emerging from the contact tip, without slippingon the feed rolls.Excessive pressure will cause the filler wire to flatten and damage its coating, as wellas undue wear and tear of the feed rolls and friction damage.LOCKED OPEN
