Even after being de-energized, they must be handled with care, because they may contain high levels of voltage, putting human life at risk. Therefore, always discharge and short circuit the capacitor terminals before handling it. This rule is also valid for all components and devices that have some electrical connection to the capacitors.
A: The danger of fire results from the effects of this intense heat upon your work and in the form of sparks and molten metals created by the arc. Q: What should you do prior to welding to avoid the hazard of fire and explosion? A: Before you start welding, inspect the work area in which you will be welding.
Therefore, they must only be applied in non-critical environments or additional mounting measures must be applied (e.g.: metal encapsulation) to ensure the safety of people, installations and prevention of fire. Motor Run capacitors may be fixed by means of fixing screw, plastic or metal clamps.
Coldman wrote: An electric motor consists of copper wire windings, you're not going to damage that with welding. Some single phase motors can have a start capacitor inside the terminal box. I don't think you are going to hurt that one either but you can always disconnect one leg while you weld to be sure.
No restrictions. No restrictions. Mounting in metallic housing When the capacitors are mounted in a metallic housing with clamps, it must not prevent or hinder the expansion of the housing. Therefore, the minimum distance between the first expandable groove and the clamp is 5 mm.
Permanent motor capacitors generally do not require discharge resistors, since the discharge of the capacitor is done via the motor windings. However, it must always be analyzed if the discharge time is sufficient, for instance, in case of single-phase motors with instantaneous reversal.

AC Capacitors
Do not perform any type of weld on the capacitor terminals, under the risk of causing deterioration of the sealing materials and disabling the capacitor safety system. Capacitors must not be used in corrosive environments, especially in the presence of hydrochloric gas, hydrogen sulfide, acids, organic solvents or similar substances.
