The lifting cylinder of the conductive copper block assembly slides up and down to drive the sliding of the conductive copper block and the output row of the conductive copper block assembly. The clamping movement of the clamp cylinder assembly of the clamp assembly clamps and connects the output copper block of the external high-frequency power supply, the conductive copper block of the conductive copper block assembly and the clamp conductive copper block of the clamp assembly. Through the perfect cooperation of the lifting cylinder of the conductive copper block assembly and the clamp cylinder assembly of the clamp assembly, the electric energy is stably and reliably transmitted to the fin edge of the special-shaped fin tube and the surface area of ​​the steel pipe at the fin bonding point.

[0035] In the welding machine output mechanism for special-shaped fin tubes, the fixture conductive copper block 203 of the fixture assembly contacts the output copper block of the external high-frequency power supply. When the fixture cylinder assembly 201 of the fixture assembly works, the fixture conductive copper block 203 of the fixture assembly is clamped to the output copper block of the external high-frequency power supply. The output row 107 of the conductive copper block of the conductive copper block assembly contacts the welding area of ​​the external special-shaped fin tube.
