Tig Welding; Remote Controls - Cebora 3.300.782/C Bedienungsanleitung

- select the mma procedure by pressing the button A:
lEd B lit.
- adjust the current based on the diameter of the electrode,
the welding position and the type of joint to be made.
- Always remember to shut off the machine and remove
the electrode from the clamp after welding.

TIG WELDING

by selecting tIG ac welding mode
aluminium, aluminium alloys, brass and magnesium, while
selecting tIG dc
iron and copper.
this welding machine is suitable for welding stainless steel,
iron, or copper using the tIG procedure.
connect the earth cable connector to the positive pole (+) of
the welding machine, and the clamp to the workpiece as
close as possible to the welding point, making sure there is
good electrical contact.
connect the power connector of the tIG torch to the nega-
tive pole (-) of the welding machine.
connect the torch connector to the welding machine con-
nector AE.
connect the torch gas hose fitting to the fitting AD on the
machine, and the gas hose from the cylinder pressure regu-
lator to the gas fitting AG on the rear panel.
Turn on the machine.
do not touch live parts and output terminals while the machi-
ne is powered.
the first time the machine is turned on, select the process
and mode using the push-buttons A and E, and the welding
parameters by means of the key P and the knob AA as
described in paragraph 3.2.
the type and diameter of the electrode to be used must be
selected according to table a:

the flow of inert gas must be set to a value (in liters per
minute) approximately 6 times the diameter of the electrode.
If you are using gas-lens type accessories, the gas through-
put may be reduced to approximately 3 times the diameter
of the electrode. the diameter of the ceramic nozzle must be
4 to 6 times the diameter of the electrode.
use d.I.N. 10 protective glasses for up to 75a, and d.I.N. 11
from 75a up.

4 REMOTE CONTROLS

the following remote controls may be connected to adjust
the welding current for this welding machine:
art. 193 foot control (used in tIG welding)
art (1268) tIG torch with potentiometer.
art (1266) tIG up/doWN torch.
art 1192+art 187 (used in mma welding)
art. 1180 connection to simultaneously connect the torch
and the pedal control.
art. 193 may be used in any tIG welding mode with this
accessory.
Remote controls that include a potentiometer regulate
the welding current from the minimum to the maximum
current set via the knob AA.
Remote controls with UP/DOWN logic regulate the wel-
ding current from the minimum to the maximum.
