The connections of the FU 11 are shown on page 4.
Cablings between different power sources and the FU are described in the operation instructions of the MULTISYSTEM power sources. The cablings of the FU 11 are carried out in the same way like in the FU 10, 20 and 30 wire
feeder units.
The FU 11 can be mounted to the MULTISYSTEM trolleys in the same way like the FU 10, 20 and 30 wire feeder
units. The FU 11 can be installed to boom using the metal lift hook (3135870), which is mounted to the plastic
handle.
Wire feeder unit must be mounted to boom in such a way that its chassis is galvanic separated both from
swing arm and boom.
Suspension angle of wire feeder unit can be changed by moving fixing point in handle.
Installation
Accessories corresponding to wire diameter
The wire feed rolls are available with plain groove, knurled
groove and with U groove for different purposes.
Feed rolls with plain groove:
Universal feed roll for welding of all kinds of wires.
Feed rolls with knurled groove:
Special feed roll for cored wires and steel wires.
Feed rolls with U groove:
Special feed roll for aluminium wires.
The wire feed rolls have two grooves for different filler
wire diameters. Correct wire groove is selected by moving selecting washer (28) from one side to another in feed roll.
Feed rolls and wire guide tubes of wire feeder unit have colour codes in order to make identification easier (see
table on page 5).
In delivery the the FU 11 is equipped with red feed rolls with plain groove and with orange wire guide tubes for
welding filler wires of 0.9-1.2mm (0.035", 0.045" and 0.052").

9907 / 1923590 / 19
For very heavy welding with 1.0-1.2 mm filler wires we recommend you to use the following feed rolls with ball
bearing, where there are deviating from other feed rolls two similar grooves:
3138650 red, with plain groove, for 1.0 mm wires
3137390 orange, with plain groove, for 1.2 mm wires
3137380 orange, with knurled groove, for 1.2 mm wires
Mounting of MIG welding gun
In order to ensure trouble-free welding check in operation instructions of gun used by you that wire guide tube and
contact tip of gun are according to manufacturers recommendation suitable to be used for wire feed diameter and
type in question. Too tight a wire guide tube might cause for wire feeder unit a bigger stress than normally as well as
disturbances in wire feed.
Screw snap connector of gun tight that there wont come any voltage losses on connecting surface.
Loose connection will heat gun and wire feeder unit.
When you are using liquid-cooled gun, mount cooling liquid hoses in such a way that the ones with the red code
always are connected to the corresponding red counter-connectors and the blue ones correspondingly to the blue
counter-connectors.
Mounting and locking of wire reel
English
LOCKED OPEN
Check that in filler wire reel are no parts sticking out, which could e.g. chafe against chassis of the wire feeder
unit. Dragging parts might expose chassis of wire feeder unit under voltage.
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 re-
main to outside position and will lock the reel.
Automatic wire feed to gun
Automatic wire feed makes change of wire reel more rapid. In reel change the pressure of feed rolls need not to be
released and filler wire goes automatically to correct wire line.
Make sure that groove of feed roll match the diameter of
welding wire used. Feed roll groove is selected by moving the groove selecting washer (28).
Release the wire end from reel and cut off the bent
28 28
Straighten about 20 cm of the wire and see that the end of it has no sharp edges (file off if necessary). A sharp
edge may damage the wire guide tube and contact tip of the welding gun.
Draw a bit of loose wire from wire reel. Feed wire through back liner to feed rolls. Dont release pressure of feed
rolls!
Press the gun switch and feed a bit wire until wire goes through feed rolls to gun. See that 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, Fc, Ss: 0,6...0,8mm, Al: 0,8...1,0 mm). Then it might be
possible that you must open feed rolls and feed wire manually through feed rolls.
length. Be careful that the wire does not spill from the
reel to sides!
Adjustment of pressure
Adjust the pressure of feed rolls with the control screw so that the wire is fed into the wire guide tube evenly and
allows a little braking when coming out from the contact tip without slipping at the feed rolls.
Excessive pressure causes flattening of the filler wire and damage to the coating. It also causes undue wear
of the feed rolls as well as friction.
Adjustment of tightness of reel brake
41
20 / 1923590 / 9907
Brake force is adjusted through hole in locking device of reel
hub by screwing the control screw (41) with screwdriver.
Adjust brake force as so big that the wire is not allowed to
become too loose on the reel so that it would spill from the
reel when the rotation of the reel stops. Need for brake force
is increased with increase of wire feed speed. Since the
brake loads for its part the motor, you shouldnt keep it unnecessarily tight.
Ground cable
Fasten earthing press of ground cable carefully, preferably direct to welding piece. Contact surface of press always
should be as large as possible.
Clean the fastening surface from paint and rust!
Use in your MIG equipment 70mm2 copper-cables. Thinner cross-sectional areas might cause overheating
of connectors and insulations.
Make sure that the welding gun in your use is designed for max. welding current needed by you!
Never use a damaged welding gun!
Shielding gas
As MIG shielding gas is used carbon dioxide, mixed gases and argon. Shielding gas flow rate is defined by welding
current size.
Gas flow regulator
Gas flow regulator should be suitable for shielding gas used by you. The regulator being in your use might be
different from the one in picture, however, following general instructions are valid for all pressure regulators.
Before mounting of flow regulator
Step aside, open cylinder valve (51) somewhat for a
51
moment, in this way you can blow out any dirt that may
be in the valve of bottle.
Screw press regulation screw (52) of regulator outwards
so long that no spring pressure can be felt (screw is
turning freely).
Close needle valve (53) if there is one in regulator
Connect regulator onto valve of bottle
Tighten connecting nut (54) preferably with a wrench.
Put hose spindle (55) of regulator with jacket nuts (56)
onto gas hose, connection should be ensured with hose
clamp (57)
Connect hose onto regulator and machine, tighten jacket
nuts.

Open valve of bottle slowly
Pressure meter (P1) shows pressure of bottle. Never use up all the gas in the bottle, send the bottle for filling up
when bottle pressure still is 2bar.
Open needle valve if there is one in regulator
Screw regulation screw (52) inwards until hose pressure meter (P2) shows flow (or pressure) required. By
regulation of flow amount the machine has to be in operation and the gun switch should be pressed on at the
same time.
Close valve of bottle always after having stopped welding
If the machine will be unused for a longer time, you should also unscrew pressure regulation screw (52).
Gas bottle
The gas bottle may explode if it falls!
Always fasten gas bottle tightly in vertical position, to wall stand or bottle cart, specially designed for it!
For safety reasons always remove gas bottle from transport stand of machine before lifting or car transport of
machine!

The burn back time is adjusted between
0,05 - 0,5s.
You must possibly adjust the burn back
time among others then when you go
over to welding of different filler wire
types, for example when you go over from steel welding
to aluminium welding. The burn back time is adjusted as
such that the filler wire doesn´t stick to weld piece or
burn fastened to contact tip at the end of welding.

Service, operation disturbances
The amount of use and the working environment should be taken into consideration when planning the frequency of
maintenance of the FU 11. Careful use and preventive maintenance will help to ensure trouble-free operation.
The following maintenance operations should be carried out at least every six months:
Check:
The wear of the grooves of the feed rolls. Excessive wear of grooves causes
problems in wire feed.
The wear of the wire guide tubes of the wire feeder unit. Badly worn feed rolls and
wire guide tubes should be discarded.
The wire guide tube in the gun should be set as near the feed rolls as possible, but
not touching them and the wire must follow a straight line from the end of the tube
to the groove of the feed roll.
Reel brake adjustment.
