My torch comes on for 2-3 seconds and machine stops! Cup light solid ! Turn off then back on and same thing!

Hope this will be Helpful .

Unfortunately it could be in either. All you can tell is that the signal wires from the button are working, Time to pull out the ohmmeter and do some testing. Test that the two parts of the nozzle actually contact before power is applied. They separate and arc to start. If they don't contact before the alarm will be set. Then verify both conductors from the nozzle parts have continuity to the torch connector. These are the tests you do with an ohmmeter with power off. If the torch parts do not make contact, it is probably a mechanical problem withthe trigger. Cable continuity can be broken at flexure points.

I have a miller spectrum 1251 for sale. We moved to a different shop that doesn't have three phase, but the machine has only been used a couple of times. You can reach me at 660-229-0171 if you are interested.

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.

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.

If you do not have the manual, you can download it for ftee here:http://www.millerwelds.com/service/ownersmanuals.php?modelThings to check would be make sure the fuel solenoid is functional, and wired to the ignition switch correctly. Also check to make sure idle speed is set correctly. If you can keep it running operating the throttle linkage manually when switched over to run/idle, the linkage itself may not be the correct length or the idle speed is out of adjustment.Also check for loose wiring to the ignition circuit or bent kill contact.It might also be some dirt in the carb bowl or low float level. Float should sit level with air horn inverted and just the weight of the float on the inlet needle valve.

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:

1. Check the power source to ensure it is providing the correct voltage and amperage.
2. Check the power cord to ensure it is properly connected and not damaged.
3. Check the ground clamp to ensure it is properly connected and not damaged.
4. Check the welding cables to ensure they are properly connected and not damaged.
5. 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.
6. Check the wire feeder to ensure that it is properly adjusted and functioning correctly.
7. Check the circuit breaker or fuses to ensure they are not tripped or blown.
8. 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.

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.

one of your PC boards may have come loose. Maybe worth popping off your cover and checking it out for yourself, see if any of the boards are loose. Is the unit mounted on rubber? If not that can help keep it from shaking itself apart. Best to you

switch from tig welding to mig by switching your current from AC to DC for mig. change from your tig gun to your mig gun. turn water flow off. proper ground and weld away.
