Difference between Medium Frequency Spot Welding Machine and Energy Storage Spot Welding Machine

Different Operating Principles:

Medium Frequency Spot Welding Machine: Abbreviated as MF, it utilizes medium frequency inversion technology to convert input AC into DC and output it for welding.

Energy Storage Spot Welding Machine: It charges capacitors with rectified AC power and releases energy through capacitors for instantaneous discharge, resulting in concentrated energy.

Different Application Ranges:

MF Spot Welding Machine: Outputs DC current with stable and almost splash-free welding due to its controllable welding time, suitable for various types of sheet metal welding, spot welding, and projection welding, making it widely applicable.

Energy Storage Spot Welding Machine: Known for its high current in a short time, it completes welding before heat spreads to the workpiece, leaving minimal traces on the surface. Ideal for workpieces with high surface requirements, but not suitable for welding thick workpieces due to uncontrollable welding time, better suited for spot and seam welding.

Different Welding Current Waveforms:

MF Spot Welding Machine: Generates a DC square wave for welding.

Energy Storage Spot Welding Machine: Produces a sharp pulse waveform.

Different Current Control Methods:

MF Spot Welding Machine: Allows precise control and adjustment of current magnitude and welding time.

Energy Storage Spot Welding Machine: Enables control of welding current magnitude but has limited or uncontrollable discharge time.

Moreover, the welding capabilities and directions of the two types of spot welding machines differ. Comparatively, the MF spot welding machine has a wider welding range, capable of spot welding, projection welding, and seam welding, suitable for welding fine and large-sized parts. On the other hand, the energy storage spot welding machine excels in welding fine parts and projections, especially in scenarios requiring high current.
