Castolin Eutectic CastoTIG, Operating Manual / Spare Parts List

A list of all the available parameters may be found in the section headed: “The control
panel”.
Select the desired parameters with the parameter selection buttons (8) and (9), and alter
them with the adjusting dial (7).
Important! All parameter command values that have been set by means of the adjusting
dial (7) will remain stored until the next time they are changed. This is true even if the
power source is switched off and on again in the meantime.
The cap-shaping function can be activated by pulling the torch trigger back. Preconditi-
on: The TIG-AC welding process must have been selected.
The cap-shaping function ensures that the
optimum shape of electrode tip is formed
automatically during the welding start-up.
A separate cap-shaping operation on a
test workpiece is no longer necessary.
Important! No further cap-shaping is
needed at the next welding start-up. After
the cap-shaping function has been perfor-
med once, it is deactivated for every
subsequent welding start-up.
Note! The cap-shaping function is not necessary if there is already a sufficient-
ly large cap at the tip of the tungsten electrode.

For an optimised ignition sequence where the TIG-AC welding process has been se-
lected, the CastoTIG 1702 / 2202 AC/DC power source takes account of the diameter of
the electrode. It also takes account of the electrode’s actual temperature, computed with
reference to the preceding welding and weld-off times.
When using any other TIG welding torch:
-Press the gas-
test button (14)
-Set the desired shielding- gas flow rate
Important! The test gas-flow lasts for a maximum of 30 seconds. Press the button again
to abort the procedure.
