Connection of welding torch
With the machine disconnected from the
supply, connect welding torch into EURO
connector and tighten well the cap nut.
Welding torch and earth cable should be as
short as possible, close to each other and
positioned at the floor level or close to it.
WELDING PART
The part to be welded must always be
connected to earth in order to reduce elec-
tromagnetic emission. Much attention must
be afforded so that the earth connection of
the part to be welded does not increase the
risk of accident to the user or the risk of
damage to other electric equipment.
Connection of the welding wire
and adjustment of gas flow
Before connecting the welding wire, it is
necessary to check the wire feed rolls if they
correspond to the profile of roll groove.
When using the steel welding wire, it is
necessary to use the roll with V-shaped roll
groove. A list of rolls can be found IN „Spare
parts of wire feeders and List of rolls.“
CHANGING OF WIRE FEED ROLL
Rolls are two-grooved. These grooves are
designed for two different diameter of the
wire (e.g. 0.6 and 0,8 mm).
•
lift the holding-down mechanism
•
screw out the locking plastic screw
and take out the roll
•
if there is a suitable groove on the
roll, turn the roll and put it back on
the shaft and secure it with a plastic
locking screw
CONNECTION OF WELDING
WIRE
•
take off the side cover of wire con
tainer put on the wire spool onto the
holder into the container
•
tighten the slotted nut so that the
roller slowed down, but it could turn
freely. If the slotted nut was tight-
ened too much, it slows turning of
the roller of wire down and it’s dif-
ficult for feeding mechanism, which
may make wire slipping in the roll
and bad feeding
•
secure the nut with a split pin cut
off the end of the wire fastened to
the edge of the roller and lead it into
the inlet guide, then through the roll
of feed into the draw-in tube 10 cm
at least
•
check if the wire leads through the
right feed groove
•
tilt the holding-down roll down and
return the holding-down mechanism
into the vertical level
•
adjust the nut pressure of thrust to
secure the wire feed without prob-
-25 -
lems and deformation by too much
thrust
•
dismount the gas tip of welding torch
•
unscrew the flow drawing tip
•
connect the socket plug into the
network
•
turn on the main switch (press the
button of the torch. The welding fire
•
is lead into the torch. The speed of
the leading-in must be adjusted with
the potentiometer with the speed of
the wire feed
•
after the run of wire from the torch,
screw the flow drawing tie and gas
tube
•
before welding use separating spray
in the space of gas tube and flow
drawing tie. In that way you prevent
adherence of metal spatter and pro-
long the life of gas tube.
CHANGES WHEN USING ALLU-
MINIUM WIRE
For welding with aluminium wire it is
necessary to use a special roll with
„U“ profile (chapter spare parts of wire
feed and list of sheaves on pg 14). In
order to avoid problems with „ruffle“ of
wire, it is necessary to use wire in diame-
ter min. 1.0 mm from alloys AIMg3 or
AIMg5. Wires from alloys A199.5 or
AlSi5 are too soft and can easily cause
problems with feed. For welding of
aluminium it is necessary to equip the
torch with teflone bovden and special
flow drawing tie. As shielding atmos-
phere it is necessary to use pure Argon.
ADJUSTMENT OF WELDING PA-
RA-METERS OF VOLTAGE AND
SPEED WIRE
Adjustment of main welding parameters
of welding voltage and speed of wire
shift is carried out with a potentiometer
of wire speed (picture A position 1) and a
voltage switch (picture 1 position 1).
You shall always allocate speed of wire
shift to adjusted voltage (switch position
1-10). Adjusted parameters depend on
used protective gas, wire diameter, ap-
plied wire type, size and position of a
weld etc.
For instance:
Welding machine KIT 2, 3, 315W, used
protective gas MIX (82% Argon and
18% CO
2
) and used wire diameter
0,8mm can be found in a chart (program
No). Adjusted values will be then –
Switch position A1 and adjusted speed of
wire shift will be 2,3 m/min.
MACHINES PROCESSOR
Setting speed of wire shift
Press button SET until you switch on
LED diode marked in the picture.
Use the potentiometer to set up required
value of shift speed within range
0,5-20
m/min
.
NOTE 1:
Speed of wire shift
can
also be
adjusted and changed during welding.
Either a potentiometer or a remote con-
trol UP/DOWN can be used. During
welding (turning the potentiometer).
NOTE 2:
Bottom display shows speed of
wire shift only if red LED diode is on
SETTING and LED diode m/min.
