Please remove the welding head, such as iron welding head or aluminum welding head, and test separately whether the current value of the vibrator can be adjusted to the lowest point (the current value must be less than 1), if the current value of the vibrator can be adjusted to the lowest point, it means There is a problem with the welding head. If the current value of the vibrator is still high, please install a normal vibrator and do a cross test on the electronic box to confirm that it is the electronic box, the vibrator or the welding head. If you have any questions, please feel free to call and contact the technical staff for inquiries.
