Weld work at the vehicle frame should remain limited to absolutely necessary exceptions.

Before performing weld works at the vehicle, it is required to disconnect the car battery. If cables are damaged which are routed not openly with the battery being disconnected, short-circuits may lead to severe damages.

When performing electric welding works, the earth terminal of the welding set must be directly connected to the vehicle part to be welded. Otherwise, the high current and the occurring high voltage peaks may damage the mechanical and electronic vehicle parts.

Only inert gas should be used for welding.

In exceptional cases, also well drained stick electrodes - 2.5 mm - with lime-basic coating may be used.

If additional brackets, etc. are welded, it is only permitted to weld in the so-called neutral zone. Plug welding is always the preferred method. Avoid weld joints running diagonally to the frame.

Note: The corrosion-inhibiting coating on the side rails is damaged in the welding area as a result of the thermal stress developing during welding. For this reason, this coating has to be suitably repaired.
