Check wiring diagram to see if it has a bridge rectifier. My 120 had one and it was bad which would not let the feed motor run. It cost me about $6.00 to replace from Ebay.

Lincoln Welder will not weld runs like a top but will not arc.

You didn't say and an internet search is vague about whether it is a MIG welder or not. You said it won't arc which sort of suggests it is a stick welder...

Assuming it is a MIG, they are full of electronics and mostly very reliable but sometimes something on one of the boards dies and it will need an experienced person to sort it out. You say it runs like a top which could mean anything from the cooling fan running to it actually pushing wire through the torch at various speeds and switching on the gas valve when you press the trigger. If that doesn't happen it would be worth checking the Euro torch internal wiring and connections. If that does happen do you hear the contactor close? A few welders have been produced that used big SCR's instead of a contactor but they are few.

If the contactor is closing and everything else seems to be working, there is probably no output from the transformer...

A more comrehensive description would have been helpful.

Our hear pump digital display is working but the top fan doesn't seem to be working.we have been away from the UK for and the unit has not been used for a while so cld that be the reason?

If you are talking about the top fan of your outside condensing unit, it could be several things. The fan motor could have failed, the run capacitor could have failed, or the motor is not getting power. Most units have a contactor that turns on the fan and compressor at the same time. If you only have one contactor, the fan motor or capacitor has failed. If you are good with a meter, check to see if you have voltage on the fan leads AFTER the contactor. If you do, I would recommend replacing the fan motor and capacitor

K star electric pool heater

Had same problem K-Star 10 both contactors, Check all your connections, I found 2 loose. If the contactor closes and can't get enough power the voltage drops, contactor starts to chatter. Loose connections also cause arcing and fires. The manual says do not store clorine in the same room.
I took the contactors out, to the bench, applied 208volts to the coil and beat on them till they stopped acting up. Put them back and they work. They are very ugly on the inside I will replace them as soon as I can find new ones on Monday..

Coleman furnace fan will not shut off .when airconditioning is turned off

Ceck the thermostat and be certain it is not in the fan mode but in the auto mode. If its in the auto mode then the realy or contactor is stuck. You can find it by following the wires from the indoor fan motor to the contactor and give it a rap with a insulated driver of some sorts and the contactors should pop out . You only do this with the power to the unif off at the breaker. If it pops out you can then restart the unit and see if it cycles as it should. But keep in mind that you may have to in the future replace the contactor. You can also go to the local hardware store and get a can of contact cleaner to remove any dirt or small bugs that like to move it to them at times. If you see the contacts (little copper pieces) burnt or really black it time to consider replacing the contactor.. Hope this Helps .. let me know jon

Auto heat control (betwixt seats) seems to have died. It worked intermittently with the motor arc getting progressively shorter until...nothing. 1984 Porsche 911 Targa

hello there
In your car do you have a hand handles to operate the heat level or it is fully automatic?
If automatic there is sensor(heat)which controls the unit.
Can you give more info about it?

My Fahrenheat baseboard strip heater is a 1996 model, 120 volts. It only works for one thermostat cycle. The thermostat points open slowly and arc as they open. The points will not reseat to supply any...

Why not get a 24 volt definite purpose contactor and connect it to power?
Use a transformer to open and close the contactor and then you can use a low voltage 2 wire el cheapo wall thermostat to turn on the heater?

Outside unit is continually on. Only way to stop it is to disconnect inside and outside units from the power. The unit has worked correctly until recently.

Sounds like your contactor has welded shut. Everytime your condensing unit turns on, you'll have a an arc of electricity across the contactor. Over time, the arcing causes to contactor to become covered in cardon. When it gets to a certain resistance across the coil, it will weld shut and the comressor and outdoor fan will run forever until the bad contactor gets replaced. If you know what a contactor is, it's a simple fix and the price is about $20 bucks. If your unsure about replacing it yourself, by all means can an HVAC contractor to replace it. 240 volts is not something you want to mess with unless you know what you are doing

CP 302 wlder

Trigger the wirefeeder while listening for the contactor on the CP302 to close, if it does start looking for loose, bad or missing ground connections to the work, then look for the power connection from the CP302 to the wirefeeder to be bad. If the CP302 contactor doesn't close look at the control cable between the wirefeeder and the CP302, try a different one if possible. If you hear the contactor close, and everything else is good, check the voltage at the CP302 output terminals to see if you may have a bad contactor.
