Tig Welding - Elettro MULTIWELD 186 SYNERGIC Manuel D'instructions

Keep the key F pressed for more than 3 seconds, with the
knob J choose the program to be deleted by displaying it on
the display I, with the knob K position yourself on dEL (display
H) and keep the key F pressed for more than 3 seconds to
confirm.
5.2.3 Updating the stored programmes
Keep the key F pressed for more than 3 seconds, with the
knob J choose the program to be updated, by displaying it on
the display I, select rCL on the display H with the knob K and
confirm by keeping the key F pressed for more than 3
seconds. At this point it is possible to amend all the recalled
welding parameters which can be saved following the
procedure described in point 5.2.1.
5.2.4 Recalling the stored programmes
Press briefly the key F once, with the knob J choose the
number of the program to be recalled displayed on the display
H, wait for 3 seconds until the welding values appear. The
LED A, B, D and E will flash, indicating that it is not possible to
amend the parameters displayed on the displays I and H.
It is also possible to display, but not amend, the parameters
relating to the service functions by keeping the key C pressed
for more than 3 seconds.
To exit the service functions displaying modality, briefly press
the C key.
To exit the memorised program and return in the working
modality, briefly press the key F twice.
6 START-UP
Make sure that the supply voltage corresponds to the rated
voltage of the welding machine.
Size the protective fuses based on the data listed on the
technical specifications plate.
6.1 MIG WELDING WITH GAS.
Connect the gas hose of the welding machine al pressure
regulator of the cylinder.
Mount the MIG torch supplied with the welding machine on the
fitting G, and connect its power terminal coming out from
fairlead N to the positive pole socket L.
Connect the earth cable to the socket M and the earth clamp
to the workpiece. Make sure that the groove of the rollers
matches the wire diameter used.
To replace if necessary: open the side door, mount the wire
coil and slip the wire into the feeder and torch sheath, block
the wire press rollers with the knob and adjust the pressure.
Turn on the machine.
Remove the gas nozzle and unscrew the contact tip (located
on the end of the torch). Press the torch trigger until the wire
protrudes.
CAUTION: keep your face away from the gun tube
assembly while the wire is coming out.
Tighten the contact tip and replace the gas nozzle.
Open the reducer of the cylinder and adjust the gas flow to 8 –
10 l/min.
Select the PROG number based on the wire diameter to be
used, the type and quality of the material, and the type of gas,
using the instructions located inside the wire feeder
compartment.
Use the button C to select the LED A (P), turning the knob K
to set the program number indicated in the instructions.
Briefly press the button C until the LED B (thickness) lights,
turning the knob K shows the thickness of the support material
you used on the display H.
The machine is ready to weld.
6.2 MIG WELDING WITHOUT GAS
The actions to prepare the machine for welding are the same
as those described previously, but for this type of welding
proceed as follows:
Mount a coil of flux-cored wire for welding without gas.
Connect the power terminal of the torch coming out from
fairlead N to the negative pole socket M.
Connect the earth cable to the socket L and the earth clamp to
the workpiece.
Select the program suited for flux-cored wire.
6.3 WELDING WITH COVERED ELECTRODES.
It is recommended that you remove the MIG torch before
welding.
Use the button C to select the LED A (P). Turn the knob K
until the display H shows the abbreviation MMA.
Briefly press the button C to select the LED E (Ampere), the
display H shows the set current while the display I shows the
open-circuit voltage.
Shut off the welding machine.
The electrode clamp must (Save for different indication by the
producer of the electrodes) be connected to the socket L
(positive polarity), and the earth cable to the negative polarity,
socket M.
VERY IMPORTANT: Connect the terminal of the earth cable
to the workpiece, making sure that contact is good to ensure
smooth equipment operation and avoid voltage dips with the
workpiece.
Turn on the welding machine.
Do not touch the electrode clamp and the earth clamp
simultaneously.
Always remember to shut off the machine and remove the
electrode from the clamp after welding.

6.4 TIG WELDING

Shut off the welding machine, remove the MIG torch and
mount the TIG torch code 535718.
Connect the power terminal of the torch coming out from
fairlead N to the negative pole socket M.
Connect the earth cable connector to the positive pole socket ,
and the earth clamp to the workpiece as close as possible to
the welding point.
Turn on the machine using the switch O.
Use the button C to select the LED A (P). Turn the knob K
until the display H shows the abbreviation TIG.
To select welding functions, access the sub-menu keeping the
key C pressed for at least 3 seconds.
Connect the gas hose to the outlet of the pressure regulator of
an ARGON cylinder.
Press the torch trigger and adjust the gas flow.
Use a 2% thorium-covered tungsten electrode (red strip),
diameter 1.6 ( 1/16" ).
Adjust the welding current using the knob K.
Strike the arc by contact using a firm, rapid stroke.
Remember to shut off the machine and close the gas cylinder
valve when you have finished welding.
7 MAINTENANCE
Periodically make sure that the welding machine and all
connections are in good condition to ensure operator safety.
After making a repair, be careful to arrange the wiring in such
a way that the parts connected to the power supply are safely
insulated from the parts connected to the welding circuit. Do
not allow wires to come into contact with moving parts or
those that heat up during operation. Mount the clamps as on
the original machine to prevent, if a conductor accidentally
breaks or becomes disconnected, a connection from occurring
between power supply and the welding circuits.
