1. A welding system comprising:
a main module having an external casing;
the casing having an inlet port for the connection to an external electric power source;
an electric generator housed within the casing and configured to adapt the electrical characteristics of the electric power received at the inlet port to a first type of welding;
the casing having at least an outlet port in electrical communication with the adapted electrical power;
an electronic controller housed within the casing and configured to control the functionality of said electric generator;
a welding torch;
an electrical conductor operative to connect the welding torch electrically to the outlet port;
wherein said welding torch includes an electronic means including a data medium in which identification data of said welding torch are stored;
wherein said electronic controller of said main module being configured, when said welding torch is connected to said outlet port, to detect said identification data from said electronic means if the welding torch is compatible with the main module, to enable the use of said welding torch; and
wherein said welding torch comprises an NFC reader configured to detect the identification data of a joint stored in an RFID tag applied near said joint, a microprocessor being configured to send said identification data to said electronic controller when said welding torch is connected to said main module, said electronic controller being configured to set the operating parameters of said electric generator of said main module based on the type of joint to be welded.
