There are various methods for connecting soft copper wires, including bolted connection, twisted connection, crimping, welding, parallel connection, series connection, and hybrid connection. The specific methods are as follows:

Bolting method. Fix the two soft copper wires with copper clamps, place them in the copper tube, tap with a hammer to make the copper tube tightly fit, and then use wire pliers to press the metal rod on the copper tube and fix the copper wire.

Twist joint method. Wrap two soft copper wires together, with a length of 8-10 times the wire diameter. Cut off the wrapped part and smoothly insert it into the electrical interface.

Crimping method. Clamp the soft copper wire with a copper sleeve and insert it into a crimper. Press the crimper's crimping head downwards to make the wire barrel shaped, and reinforce it with a copper clamp.

Welding method. Clean the surface of the soft copper wire, use solder wire to weld the copper wires together, and pay attention to controlling the welding time.

Parallel docking method. Peel off the outer skin of the flexible wire, expose the inner core, twist the corresponding colored wires together, and wrap the connecting parts with insulating tape.
