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.
There is a bimetalic strip and a magnet that can get stuck in the closed position.
Tapping the iron on the end of the bit can release it otherwise a new element will be required.

Try straightening out the cables. Also, Clean and tighten all weld connections (see Section 9-1). Check for and remove anything blocking fan.
To check if there is a signal from the switch on the gun, depress the switch and the wire should start to move out. If it does, the main board has a fault, if it doesn't, it may be a faulty switch.
If your Lincoln Ranger 250 gas welder is running but not striking an arc, there could be a few potential issues causing this problem. Here are some steps you can take to troubleshoot the issue:
1. Check the welding leads and connections: Ensure that the welding leads are securely connected to both the welder and the workpiece. Make sure the connections are tight and free from corrosion or damage.
2. Check the electrode/ground clamp connections: Inspect the electrode holder and ground clamp connections for any loose or damaged parts. Ensure that the electrode holder is securely gripping the welding electrode.
3. Check the welding electrode: Examine the welding electrode for any signs of damage or wear. Replace the electrode if it appears worn out, as it may not strike an arc effectively.
4. Check the power source: Verify that the power source to the welder is adequate. Ensure that the welder is receiving the correct voltage and that the power source is providing sufficient power.
5. Check the welding settings: Review the welding settings on the welder to ensure they are appropriate for the type and thickness of the metal you are working on. Adjust the settings if necessary.
6. Check the welding environment: Make sure you are operating in a clean and well-ventilated area. Remove any contaminants or debris from the workpiece and ensure good contact between the workpiece and the ground clamp.
7. Check the welder's internal components: If the above steps do not resolve the issue, it may be necessary to inspect the internal components of the welder. This requires expertise and should be performed by a qualified technician. Contact a professional repair service or the manufacturer for assistance.
Remember, safety is crucial when working with welding equipment. Always follow proper safety precautions and wear appropriate protective gear, such as welding gloves and a welding helmet, to protect yourself from potential hazards.

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 the wire feed on your Hobart 251 MIG welder won't stop when you turn it on, there could be a few possible causes. Here are a few things to check:
Check the trigger on the MIG gun: Make sure that the trigger on the MIG gun is not stuck or damaged. If the trigger is stuck in the "on" position, it will cause the wire to continuously feed.
Check the wire feed motor: The wire feed motor could be faulty or jammed, causing the wire to feed continuously. Try disconnecting the wire feed motor from the welder and see if the wire still feeds. If it does not, then the motor is likely the problem.
Check the wire spool: Make sure that the wire spool is installed correctly and is not jammed or tangled. If the wire is not feeding smoothly from the spool, it could cause the wire to feed continuously.
Check the wire feed control settings: Ensure that the wire feed control settings are set correctly. If the wire feed speed is set too high, it could cause the wire to feed continuously.
If none of these solutions resolve the issue, it may be best to contact a qualified technician or the manufacturer for further assistance.
