Argon gas from a cylinder with a flow regulator must be used for this gas. The torch must be connected directly to the
regulator. The equipment does not have an electrovalve to control the gas flow, so the use of a torch with a knob is
recommended for regulation and interruption of gas flow. It is recommended to adjust a gas flow of 10 to 20 l / m or 21
to 0 CFH. The arc starting mode in TIG is LIFT ARC, which means that to start the arc it is necessary to join the tungsten
electrode against the workpiece, hold it for a few moments and separate it, as shown in the following images:
