Functions of Di-electric Fluid:

• It should act as an insulator until the required breakdown voltage attained.
• It should act as a conductor, once the breakdown voltages are reached.
• It should clean the spark gap by carrying away the molten metal.
• It should de-ionize the spark gap rapidly after the discharge has occurred.
• It should cool the tool, work piece and the spark region
