turn switch 10, select TIG and press
confirm.
Inert gas welding with an infusible Tungsten
electrode (TIG: Tungsten Inert Gas) for
short, is a welding procedure whereby the
heat is produced by an arc that strikes
between a tungsten electrode (which is not
consumable) and the workpiece. The
welding is carried out by fusing the edges of
the workpiece or by adding other filler
material using specific types of rod to create
a joint. The torch is ignited by touching the
workpiece with the electrode and then lifting.
The TIG procedure can be adapted to any
work position and can also be applied to
very thin sheets of metal (0,2-0,3 mm). The
TIG procedure is distinguished by the ease
with which the arc can be controlled, a
powerful and concentrated thermal source
and the simple manner in which the filler
material can be controlled. This makes the
TIG procedure particularly suitable for
precision welding on a wide variety of
thicknesses, in difficult positions and on
pipes which require full penetration. The TIG
procedure can be used on various types of
metals, such as, ferrous materials, alloys,
nickel, copper, titanium, magnesium.
During welding, potentiometer 9 in fig. 1, for
example, regulates the welding current.
The correct connection of the torch and
earth cable is shown in the following table:
