Warning
Failure to follow all welding safety precautions, including the use of personal protective equipment, could result in serious injury or property damage. Only technicians who have completed Tesla’s approved welding training are authorized to weld structural components on Tesla vehicles.

Warning
To maintain vehicle crash integrity, use only approved welding wire and an approved GMA welder to perform GMA welding on Tesla vehicles. Refer to Approved Gas Metal Arc (GMA) Welders and Welding Wire for information on approved GMA welders and welding wire.

CAUTION
Do not weld on a Tesla vehicle before performing the Vehicle HV Disablement Procedure (refer to the vehicle-specific Service Manual for more information on the Vehicle HV Disablement Procedure). Welding on a Tesla vehicle with an energized high or low voltage system might damage vehicle components.

Note
Before GMA welding, a test weld using material of the same gauge and type should be performed to make sure that the welding equipment settings produce a satisfactory joint.
