3.4 WELDING BY TIG PROCEDURE.
In TIG welding we must only use straight polarity, placing the welding torch in the negative pole. In addition, in
the installation, we must place a gas bottle O, (normally Argon), which we will connect to the machine through
pressure regulator N as seen in the figure below.

In TIG welding it is possible to set the following parameters related to the current:
