Squeeze Time

Controlling the electrode force is a critical part of successful resistance welding. Repeatable weld force provides for consistent welds. For this reason, all AMADA WELD TECH weld heads include a standard force-firing feature that initiates the power supply when a preset electrode force is reached. In addition to force firing, a sufficient amount of squeeze time, typically 150 milliseconds (9 cycles @ 60 Hz.), is required to allow the weld head to settle prior to the application of weld current.
