Why does the WTC Welding System circuit breaker trip on power-up?
C
Christopher ShawAug 16, 2025
If the circuit breaker trips on power-up, it could be due to several reasons. The SHUNT TRIP output on the I/O might be active; if so, check if the primary transformer cables are grounded or if the SCR is breaking over at a low potential or is shorted. Another cause could be a faulty inverter, in which case you should replace the inverter assembly. Finally, the circuit breaker itself might be faulty, requiring replacement.

Dr. Shelly McbrideAug 18, 2025
If the WTC Welding System circuit breaker trips while welding, it could be because the magnetic trip on the circuit breaker is set too low. Adjusting the circuit breaker’s magnetic trip threshold may resolve this. Alternatively, the SHUNT TRIP output on the I/O module might be active when the SCR is not shorted, in which case replacement is necessary.

Why doesn't the WTC MedWeld 5000 control initiate a weld schedule?
J
Joel SmithAug 21, 2025
If the WTC Welding System control does not initiate a weld schedule, it could be due to a couple of reasons. First, the control might not be receiving BINARY SELECT inputs. Check the device supplying the inputs, the timer module, and the input supply voltage to the timer module, and also check the I/O Status Display at the DEP. Second, the control may have detected a fault condition. Check the DEP-100S to determine which fault condition was detected, clear the fault(s), and re-initiate.

What to do if the WTC Welding System control is not responding to DEP-100S?

If the WTC Welding System control is not responding to the DEP-100S, check the connection between the timer unit and DEP-100S. If networking, check for improper or loose wiring at the MedLAN connection, ensuring the wiring is secure and proper. If problems persist, the timer, DEP-100S, or Network Power Pack may be faulty and require replacement.

Why is the WTC MedWeld 5000 processor not in Run Mode?

simonstephanieAug 28, 2025
If the WTC Welding System processor is not in Run Mode, even though all processor LEDs are functioning normally, it could be due to an improper mode selection. Verify the processor mode selected and, if it is in Program or Test mode, return to Run Mode. Another cause could be that the line power is out of range. Check the jumper setting on the power supply to ensure it matches the input voltage. Also, check for bad connectors or improper seating of the power connector by removing power and inspecting the power supply and processor connections. You can also try the existing power supply in a test chassis and replace the power supply if it's unsuccessful.

What causes the WTC MedWeld 5000 Welding System timer to not communicate?
C
Corey WilsonAug 30, 2025
If the WTC Welding System timer cannot communicate and the CPU Fault LED on the processor is on, it could be due to bad connectors or improper seating of the timer unit in the chassis. Remove power, inspect the timer unit connections, and then cycle power. Another possible cause is incompatible timer firmware. Verify compatibility and correct as needed. If compatibility is unknown, consult your WTC representative for assistance.

How to troubleshoot inadequate power to the WTC Welding System processor?
D
Dennis BraySep 2, 2025
If there is inadequate or no power to the processor of the WTC Welding System (and all LEDs are off), first verify that line power has been connected to the power supply. Next, check the fuse and replace it if it is blown. If the power to the processor has been cycled too fast, remove power to the processor for a minimum of two minutes, then restore power. Finally, the power supply could be defective and need replacement.

Joseph BurtonSep 5, 2025
If there is inadequate or no power to the timer unit of your WTC Welding System but the power supply LED is on, it could be due to several reasons. First, check for bad connectors or improper seating of the power supply and/or timer unit in the chassis by removing power and inspecting the connections. Second, check the fuse on the power supply and replace it if blown. Third, verify that line power is connected to the power supply. Finally, check the jumper setting to verify that it matches the input voltage.

Gwendolyn GutierrezSep 9, 2025
If the WTC Welding System controller is inoperable, but no major CPU faults are detected, it could be due to defective I/O devices or I/O wiring. Test the inputs and outputs, according to the I/O Troubleshooting section.

Why am I experiencing loss of RAM memory in my WTC Welding System?

If you are experiencing loss of RAM memory in your WTC Welding System (and the Batt LED is on), it is likely that the battery on the timer unit is low or dead. Replace the battery on the timer.
