Work coil:

The work coil consists of a water-cooled induction coil that is powered by a radio frequency generator. A copper induction coil is wrapped two or three times around the ICP torch and has water flowing through it for cooling purposes. The lines of force generated through the magnetic field and are directed along the axis of the solenoid inside the tube and take the form of an ellipse on the outside.

Argon gas supply:  The conventional argon plasma torch uses between 13 and 20 liters of argon per minute, majorly to ensure in which the outer quartz glass tubing adjacent to the plasma is adequately cooled. Like a high consumption of argon gas is met by installing a liquid argon supply Dewar flask rather than relying on conventional compressed gas cylinders.
