AP5K-B is the pneumatic double-independence pressure-adjustable double-pulse AC integral precision spot welding machine with double welding spots. Its advantages can be described as follows:

1)      Control power supply: with integral design, the welding head is small in size and easy to be installed and adjusted.

2)      The double-pulse current output can effectively enhance the welding quality, particularly suitable to welding clad materials.

3)      The half-wave control can shorten the welding time, effectively reduce the thermal impact on the work pieces and avoid discoloring and deforming.

4)      The automatic mains voltage compensation can keep the welding quality from being influenced by the fluctuation of the mains voltage.

5)      The digital setting for the welding parameters is precise and can be easily adjusted.

6)      Ten-set welding procedure record brings facilitations in production and application.

7)      The precise welding pressure following mechanism can be used for adjusting the welding pressure accurately and guarantee consistency of the welding.

8)      The height of the welding head and the maximum stroke range can be adjusted so as to meet requirements of different work pieces.
