It sounds like there may be a problem with the internal circuitry of your Lincoln 100 welder. Given that the welder is tripping the breaker and dimming the lights in the garage, there may be a significant amount of current passing through a fault in the machine's electrical system.

I would recommend that you do not attempt to operate the welder until the issue has been resolved. Welding equipment can be dangerous if not properly maintained and operated, and it's important to take safety precautions to avoid injury or damage to your property.

Since you've already inspected the inside of the welder and didn't find anything obvious, it may be best to take it to a qualified repair technician. They will have the expertise and equipment to diagnose and fix any problems with the machine's electrical system.

Alternatively, you can contact the manufacturer's customer service for guidance or recommendations on qualified repair technicians in your area. They may also be able to provide additional troubleshooting steps to help diagnose the issue.

In any case, safety should always be your top priority when working with electrical equipment.

Question edited for a lot more clarity, 'make model (what it is)' in the correct order. The thing about Speech to Text, is that you MUST go back through it and add punctuation or it all runs into one sentence. I did that for you as well into what I think you thought you were saying! This is an antique from the early 1950s. There is a picture of the inside wiring here https://weldingweb.com/vbb/threads/703256-Old-Marquette-Welder-wiring-question Manual for a Model 60 and 60C https://www.ebay.com/itm/115540831572 More here https://www.google.com/search?q=Marquette++Model+64+Farm+Welder+wiring+diagram ..

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.

Magnetic reed switch near output is probably bad. Look for coil behind front panel, there is a small glass tube inside, with 2 small wires.

Overheating can cause damage to the internal components of a welder, including the wire feed motor, transformer, and electronic components. It's possible that the high setting on your Campbell Hausfeld WF2050 welder has been damaged due to the overheating. You may need to check the high setting circuitry to see if there are any visible signs of damage, such as melted wires or burnt components. If you're not familiar with electrical components, it may be best to have a qualified technician or electrician check the welder for you. Alternatively, it's also possible that the wire feed motor may have been damaged during the overheating. A damaged wire feed motor can cause the wire to feed improperly, which can affect the quality of the weld. You may need to check the wire feed motor to see if it's functioning properly. In any case, it's important to address the overheating issue to prevent further damage to your welder. Make sure that the welder is being used in a well-ventilated area and that the cooling fan is working properly. Additionally, make sure that the welder is not being overloaded by using the appropriate amperage setting for the job.

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:

1. 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.
2. 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.
3. 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.
4. 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.

If the wire feeder is not working, it's possible that one or more of the wires you reconnected are not in the correct position or may have come loose. Double check to make sure all the wires are securely attached and in the correct order. It's also possible that the wire feeder motor itself may be faulty or damaged, especially if it was not working properly before you opened it up. You could try testing the motor with a multimeter to see if it is getting power and functioning correctly. Finally, make sure that the wire spool is loaded correctly and that the tension on the wire is set properly. If the wire is not feeding correctly, it could be due to a problem with the spool or tension.

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.

If it's a Perkins engine, odds are that you need a rebuild kit for the governor or a new governor to maintain the idle. It's a fairly common issue and repair.

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

'this welder'. The one that only you know what it is?

for welding cars or similar thickness steel use it on number1 setting speed 6-7 and practise max and min should be used when you want a bit more power A gose onto number 2 and then 3 these are amp settings and are for thickness of steel to be weled your welder can weld up to 8mm of plate steel on setting 3 max i use 0.9mm gasless flux cored wire great for working out doors the wind tends to blow gas away on standard wire yours is easly converted to gasless as so was mine

My welder will only run above full at full line it dies why

Hi, please for damaged wires, check that a technician has blown out dust from the rear portion of your welder after dust has been removed and double check that you've cleaned the exterior within the last 2 months. Thank you.

This could be a PWM issue with the controller or the pinch rollers for the feed are worn or slipping,

The only things that come to mind after your checks are a spool not set in completely, a stripped spool or a spool drive shaft failure of some kind. so...make surenthe spool is not stripped, its seated all the way and if so is the drive shaft for the spool and/or feeder pulleys all moving. If nothing is moving anywhere but you hear the actuator motors turning inside you have a warranty issue.

A lot of wire feeding problems can be cured by changing the contact tip. It only takes a little contamination, weld splatter, arcing to cause the symptoms you've described. With over 40 years experience with wire feed welder I've found that 9 out of ten times feeding problems are tip related. The drive roll tension cab sometimes cause the symptoms you're describing. Also keeping your mig torch as straight as possible, no curls or bends will help eliminate feeding issues.
