Introduction to the Mid-Frequency Spot Welding Machine Transformer

The transformer of the mid-frequency spot welding machine is likely familiar to everyone. The resistance welding transformer is a device that outputs low voltage and high current. It generally has an adjustable magnetic core, large leakage flux, and steep external characteristics. By using a switching device on the primary side of the transformer, the number of turns of the primary winding of the resistance welding transformer can be changed to adjust its secondary voltage, thereby regulating the output (welding) current to meet certain welding process requirements. It typically has an adjustable magnetic core, large leakage flux, and steep external characteristics.

The secondary winding of the mid-frequency spot welding machine transformer has only one or two turns. Usually, only the number of turns of the primary winding can be changed to adjust the welding current. This not only complicates manufacturing but also reduces the reliability of the transformer. A microcomputer cross-flow controller can adjust the welding current, so it replaces the switching of primary winding turns to adjust power.

The primary winding is made of flat copper wire wound into a coil shape, while the secondary winding generally consists of one turn and is made of multiple pieces of copper plates or copper tubes connected in parallel. Each piece has cooling water pipes welded to the outer edge for cooling purposes. When copper tubes are used for the secondary winding, they also serve as water pipes for cooling.

The arrangement of the primary winding is to sandwich one primary winding component on each side of each secondary winding component to form a combination unit. The number of combination units required for a resistance welding transformer depends on the capacity and structural requirements of the transformer and is arranged according to design calculations.
