P-7 error in miller co2 welding machine
The P-7 error in your Miller XMT 304 CC/CV welding machine indicates that the input voltage is too high, causing the unit to automatically shut down. However, operation will resume when the voltage falls within the acceptable upper range limit (which is 15% above the applicable input voltage). Here are some steps you can take to troubleshoot and address this issue:
Check Input Voltage: Verify that the input voltage is within the specified range for your machine. If it exceeds the acceptable limit, consider adjusting the power source or using a different power supply.
Inspect Bleeder Resistors: The P-7 error is often related to the side output board, particularly the bleeder resistors. Ensure that these components are functioning correctly. If any of them are faulty, replace them.
Examine IGBTs: Inspect the IGBTs (Insulated Gate Bipolar Transistors) on the side board. Even if they appear fine, remove the output board and verify the protection diodes on it. Sometimes, an IGBT may have a damaged base that isn't immediately obvious.
Be Cautious: When working on the machine, be extremely careful. There are high voltages (around 325 volts) stored in the large capacitors, which can be fatal if mishandled. Always wear appropriate protective gear and follow safety precautions. The complexity of the device may require expert assistance.
I have a Miller Synco Wave 350 DX TIG/arc welder but my Remote 14 is not reading my pedal. I checked the pedal and its good. I turned welder off unplugged the pedal, turned welder back on.
Based on the information provided, it seems that there may be an issue with the Remote 14 connection on the Miller Synco Wave 350 DX TIG/arc welder. Here are some steps that can be taken to troubleshoot the issue:
1. Check the Remote 14 connection: Make sure that the Remote 14 connector is securely plugged into the welder. If it is loose or not fully connected, this could cause issues with the pedal not being recognized.
2. Check the pedal connection: Ensure that the pedal is properly connected to the Remote 14 connector. If it is not plugged in all the way or if there is any damage to the cable, this could cause issues with the pedal not being recognized.
3. Check for error codes: The Miller Synco Wave 350 DX TIG/arc welder has a built-in diagnostic system that can display error codes if there is an issue with the machine. Check to see if any error codes are displayed and refer to the user manual for troubleshooting steps.
4. Contact Miller customer support: If none of these steps resolve the issue, it may be necessary to contact Miller customer support for further assistance.
In summary, if your Remote 14 is not reading your pedal on your Miller Synco Wave 350 DX TIG/arc welder, you should check the connections, look for error codes, and contact customer support if necessary.
My Miller Dynasty 300 isn't putting out any current to stick weld?
The issue you're experiencing with your Miller Dynasty 300 not putting out any current to stick weld could be caused by a few different things. Here are some things you can try to fix the problem:
- Check the power source to ensure it is providing the correct voltage and amperage.
- Check the power cord to ensure it is properly connected and not damaged.
- Check the ground clamp to ensure it is properly connected and not damaged.
- Check the welding cables to ensure they are properly connected and not damaged.
- Check the contact tips to ensure they are not worn or damaged, and that the correct size is being used for the wire being used.
- Check the wire feeder to ensure that it is properly adjusted and functioning correctly.
- Check the circuit breaker or fuses to ensure they are not tripped or blown.
- If the above steps do not resolve the issue, it may be best to take the welder to a professional technician or contact the manufacturer for further assistance or service.
It is important to note that, the above steps are general troubleshooting steps, and the actual problem can be caused by different things, so it is best to consult a service manual for your specific Miller Dynasty 300 welder or contact the manufacturer for more detailed and accurate information.
Miller 22G high idle issues
The toroid transformer (looks like a donut) has wires, and connectors which feed a small voltage to the idle module. Since works with grinder, I'd look for corroded connections including rusty grounds. It takes one volt ac to idle mod to trigger.
