Welding Tools - Answered Questions & Fixed Issues

Louis D Biasi You resurrected a 12 year old unanswered question which will now stick on the Homepage, 'Unsolved' despite being answered. It is always better to make a squeaky fresh, clean question of your own. The area where you posted is the 'Additional Information' information are so perhaps the OP can take his apart for you, but where the trigger connects should be pretty straight forward. Electrical schematics are available. Here are some manuals https://www.manualslib.com/brand/mishto/welding-system.html But is appears to also go by the name of 'Rossi'. Better manual here https://www.manualslib.com/products/Rossi-Welders-Weld-Mig220bz-3941072.html ..

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 the same problem with the Mighty Mig...Did you find these resistor values?

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.

It looks like Hobart made 3 different versions of the 10,000. If you go to their website and enter the model # (and serial #), you can download the exact owners manual with complete parts listing (according to their site). The website is: http://www.hobartwelders.com/service/owners-manuals

The part should be available from them..or with the part number, you can google it and see what is out there in the secondary market.

Hope this helps

Never heard of a 'Wing machine'?

Question edited for clarity. If it was running before with no problems, I switch or controller is unlikely to have suddenly failed. The most likely answer is the the mouse wiring repair has caused the fault, bad connection missed connection, misplaced connection.
