Press type spot welders replace the pivoting rocker arm with a straight linear electrode stroke – the upper electrode moves directly down onto the workpiece in a true vertical press motion. This linear action generates higher, more uniformly distributed electrode force compared to a rocker arm, and maintains that force consistently regardless of stack-up thickness variation. The result is superior weld quality on heavier gauge materials, multi-layer assemblies, and applications where electrode force consistency is critical to achieving a sound weld nugget. Available in AC and MFDC.
