How to fix overtemperature on Thermal Arc ULTRA FLEX 350?
If your Thermal Arc Welding System is showing an overtemperature error, it could be due to several reasons: * Exceeding the duty cycle rating. * Excessively high ambient temperature. * Blocked airflow. * Fan failure. To resolve this, reset the machine by briefly turning off the main power switch.
What to do if Thermal Arc ULTRA FLEX 350 shows over/under voltage of the AC line?
If your Thermal Arc Welding System indicates an over/under voltage of the AC line, it means the input AC voltage is either too high or too low. To address this, check the AC line voltage and reset the machine by turning the main power switch off and then back on.
