Digital welder

The digital welding machine is a microprocessor controlled by a microprocessor. Using DSP, ARM and other embedded microprocessors to control the welding machine, operation, welding current, welding voltage regulation, vibration time, delay time, energy, power are all processed by the microprocessor. The whole process of welding is all working in the visual mode. It is convenient and quick to debug the workpiece, and supports the data export function, which perfectly solves the trouble of debugging in the next use and the data uniformity.

This machine adopts square column dovetail groove design to reduce backlash and make the machine more stable. Control time accuracy of up to 0.001 seconds, can be added to machines for special purposes.
