Changes when using aluminium wire
For welding with aluminium wire it is necessary to use a special roll with „U“
profile. In order to avoid problems with „ruffle“ of wire, it is necessary to
use wire in diameter 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 atmosphere it is necessary
to use pure Argon.
Adjustment of gas flow
Electric arc and welding pool must be perfectly protected by gas. Too little
amount of gas cannot create necessary protective atmosphere and on the
contrary, too big amount of gas entrains air into electric arc, which makes
the weld imperfectly protected.
Proceed as follows:
• fix the gas tube with the filter on the gas input on the back side of the
machine (pic. 2A/b, pos. 20)
• if you use gas carbon dioxide, it is suitable to plug in gas heating (during
the flow less than 6 litres/min the heating is not necessary)
• plug in the cable of heating into the socket (pic. 2A/b, pos. 21) on the
machine and into the connector at cylinder pressure regulator, polarity is
not important
• press GAS TEST button - turn adjustment screw on the bottom side of
pressure valve until flow indicator shows required flow, then release the
button
• if the machine was not used for a longer time, or after entire change of
welding torch, it is recommended to blow ways by fresh gas before you
start welding
Adjustment of welding parameters
machines STANDARD
Adjustment of main welding parameters of welding voltage and speed of
wire shift is carried out with a potentiometer of wire speed (pic. 1A/b, pos.
11) and a voltage switch (pic. 1A/b, pos. 3, 6). you shall always allocate spe
-
ed of wire shift to adjusted voltage (switch position 1-40).

1 - both potentiometers switched off - function switched off, normal welding
2 - left potentiometer active / Right Off - Set the spot time
3 - both potentiometers active - set the pulse time
machines PROCESSOR/SYNERGIC
Setting of main welding parameters - welding voltage and wire feed spe
-
ed - is done by a potentiometer (pic. 4 b/C, pos. 1) and a voltage switch
(pic. 1A/b/C, pos. 3, 4). The wire speed is always assigned to the set voltage
(switch position 1-40).
Setting speed of wire shift
Press button SET until you switch on lED marked in the picture.
Use the potentiometer to set up required value of shift speed within range
1-20 m/min
The welding torch and the grounding cable should be as short as possible,
close to each other and located at or near floor level.

Welding part
The part to be welded must always be connected to earth in order to re
-
duce electromagnetic 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.
Changing of wire feed roll
Rolls are two-grooved. These grooves are designed for two different diame
-
ter of the wire (e.g. 0.8 and 1.0 mm).
• lift the holding-down mechanism
• screw out the locking plastic screw and take out the roll
• if there is not a suitable groove on the roll, turn or replace 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 machine
• put on the wire spool onto the holder (pic. 3, pos. 25)
• cut off the end of the wire fastened to the edge of the roller and lead it
into the loading bowden (pic. 3, pos. 27), then through the roll of feed
into the loading tube (pic. 3, pos. 28) 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 pro
-
blems and deformation by too much thrust
• adjust the welding wire coil brake so that the coil turns freely when the
feed mechanism is switched off. Too tightened brake greatly straps the
feed mechanism and wire may slip in the pulleys and misfeed. The brake
adjusting screw is located under the plastic screw of the bobbin holder
(pic. 5).
• dismount the gas tip of welding torch
• unscrew the flow drawing tip
• connect the socket plug into the network
• turn on the main switch into pos. 1
• press the wire feed button on the control panel
• after the run of wire from the torch, screw the flow drawing tie and gas
tube
• connect the protective gas to the gas valve (pic. 2b, pos. 22)
• before welding use anti-spatter 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
