A variety of options exist for overcoming the basic, but frustrating hurdle of a malfunctioning control panel that prevents you from initiating critical projects.
First and foremost, determine whether power is properly sent to the ultrasonic welding equipment. Faulty or underpowered supplies often prevent devices from being turned on in the first place, thereby making control panels impossible to operate. Another potential problem: the outlet may lack sufficient wattage.
Once you've verified that your welding equipment is properly powered, consider resetting the internal software that the control panel relies on to operate the user interface. Software varies significantly between models, but specific steps can typically be found within each unit's operations manual.
If you ultimately opt to reset the equipment's software, expect all settings to revert to their factory defaults. As such, this option is best avoided if you've configured equipment in a way that could require in-depth recalibration in the event of altered settings.
If, upon resetting your machine's software, you still struggle to use the control panel, the screen itself could be burned out or otherwise faulty, thereby necessitating a swift replacement.
