Traditional copper wire butt welding machines generally use contactors to control the size of the current. The upper contacts of the contactor connect and break the copper strips below, and they often need to be pressed to connect. We often hear the sound of "bah-bah-bah-bah", the leaves are noisy, and the service life is limited, usually about 5,000 times.

Pressure welding is a welding method that must apply pressure to the weldment during the welding process. The copper wire butt welding machine belongs to the resistance welding machine category, and resistance welding must also be pressurized to weld.

The choice of manual copper wire butt welding machine is determined based on the common copper specifications and actual frequency of use of wire and cable companies, wire drawing, and non-ferrous metal manufacturers. Generally, the butt is made before and during drawing, while drawing is to pull the whole circle and the whole roll, and the frequency of needing to be connected is not high.

The three major parameters of the copper wire butt welding machine include welding current, welding time and upsetting force. Some have a ramp-up time (the current rises steadily, designed to suppress splashing)

After welding copper wires, aluminum wires, iron wires, and steel wires with a multi-functional copper wire butt welding machine, there are many ways to check whether the joints are good or not. Joints of different grades and materials have different quality inspection standards.

There are many types of copper wire butt welding machines, from manual, manual CNC, pneumatic to programmed pneumatic casting transformer. Each one is more complex than the other, more advanced and precise than the other, and the price is also increasing step by step.

The power of copper wire butt welding machines ranges from small to large. The diameter or cross-sectional area of the copper wire is mainly used to determine the corresponding power of the butt welding machine. There are also manual and pneumatic, and more complicated ones are ordinary and programmed. Depending on the transformer, the difference is also relatively large.

Before using the multi-function butt welding machine, you must first keep the welding end faces of the two workpieces at least 3-5mm identical in shape and size to ensure consistent heating and plastic deformation of the workpieces.

Multifunctional butt welding machines have high production efficiency. Even manual butt welding machines are 3-5 times faster than manual welding machines, let alone automatic butt welding machines, so they are widely used.
