Yesterday, a Giga Press at Tesla's Fremont factory caught fire, which was quickly extinguished. No Tesla personnel or fire brigade was injured. The cause of the fire hints that the Giga Press can be repaired shortly and return to full operation.
On March 11, at 4:27 PM, Fremont firefighters answered a call to Tesla's Fremont factory. At the scene of the incident, "the deep-seated fire was contained to a vehicle manufacturing stamping machine" was reported. Video from the scene showed white smoke coming from Giga Press.

A hydraulic system uses pressurised fluid to drive machinery. Most hydraulic fluids are combustible and a compromised hydraulic system, in combination with an ignition source, can lead to a fire. This is exactly what happened: the hydraulic fluid hit the molten aluminum, which was very hot.
According to people familiar with this type of fire in casting machines, their consequences can be eliminated in a few days and boil down to cleaning the sand used to extinguish this fire, cleaning and replacing parts, if necessary. Judging by the video, which shows that the workers are in close proximity to Giga Press, and the statement of the firemen, this was a frivolous fire. Thus, the giant machine is expected to return to operation shortly.
