Tig Welding - Cebora TRI STAR MIG 1635/M Manual De Instrucciones

To confirm the desired function, simply hold down the
button V for 3 seconds. The abbreviation shown on the
display N will begin flashing; after a few seconds, a sound
will confirm that it has been saved.
6 INSTALLATION
The welding machine must be installed by skilled person-
nel. All connections must be made in full compliance with
current safety laws.
6.1 PLACEMENT
Position the equipment in an area that ensures good sta-
bility, efficient ventilation so as to prevent metal dust (i.e.,
from grinding) from entering.
7 START-UP FOR MIG WELDING WITH GAS.
Mount the plug on the power cord, being especially care-
fully to connect the yellow/green conductor to the earth
pole. Make sure that the supply voltage corresponds to
the rated voltage of the welding machine. Size the pro-
tective fuses based on the data listed on the technical
specifications plate.
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 E, and connect the power terminal leaving
the torch to the positive pole (socket H).
Connect the 2-pin connector leaving the torch to the
socket F.
Connect the power plug of the earth cable to the socket
G and the earth clamp t the workpiece. Make sure that
the groove of the rollers matches the wire diameter used.
To replace if necessary (Fig. 3):
BN
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 BN 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
10
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.
7.1 WELDING.
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 feed-
er compartment.
Use the button V to select the LED D (PROG), turning the
knob I to set the program number indicated in the instruc-
tions.
Briefly press the button V until the LED C (thickness)
lights, turning the knob I shows the thickness of the sup-
port material you used on the display M.
The machine is ready to weld.
7.2 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 cable leaving the torch to the negative
pole (socket G).
Connect the earth cable to the positive pole (socket H).
Select a program suited for flux-cored wire.
7.3 WELDING WITH COVERED ELECTRODES.
It is recommended that you remove the MIG torch
before welding.
Use the button V to select the LED D (PROG). Turn the
knob I until the display M shows the abbreviation MMA.
Briefly press the button V to select the LED A (Ampere),
the display M shows the set current while the display N
shows the open-circuit voltage.
Fig. 3
Shut off the welding machine.
The electrode clamp must normally be connected to the
socket H (positive polarity), and the earth cable to the
negative polarity, socket G.
VERY IMPORTANT: Connect the terminal of the ground-
ing 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.
In any case, observe the polarity shown by the electrode
manufacturer.
Always remember to shut off the machine and remove
the electrode from the clamp after welding.

7.4 TIG WELDING

Shut off the welding machine, remove the MIG torch and
mount the desired model of TIG torch.
Connect the mass cable connector to the positive pole (+)
of the welding machine, and the clamp to the workpiece
as close as possible to the welding point.
