The welding time of plastic terminals should not exceed much.

Five seconds. According to the query of terminal crimping process specification, the corresponding power supply iron should be selected according to the bare wire diameter when welding cold terminals, and the welding time of each contact should not exceed 5 seconds. Be careful not to let the flux enter the insulation, so as not to reduce the insulation resistance of the product, so the welding time of the plastic terminal should not exceed 5 seconds. Plastic welding refers to the connection method that the contact surfaces of two plastic parts are melted at the same time by heating, thus combining them into a whole.
