The casting apparatus has a case defining a casting chamber having an open front provided with a door, and a crucible locatable in the chamber for containing metal loads to be cast. An electrode extends through a wall of the chamber and is connectable to a power source for the formation of an electric arc between the electrode and the load in the crucible. A coupling connects the inside of the chamber to a source of pressurized inert gas or to a vacuum pump. A tubular element for containing a mold is removably accommodatable in the chamber at an opening, which is connected to the atmosphere by a vent valve. A fluid-activated jack is provided for tilting the case for pouring molten metal, from the crucible to the mold contained in the tubular element.
