There is the possibility that that the tensioner for the wire rollers is too tight. If this is the case here is a good rule of thumb for any make wire welder. Run the wire out of the tip about an inch or so, grab the wire with your fingers, now pull the trigger. If the wire is pushing your fingers back with a good amount of force loosen the tensioner, and repeat this procedure until the wire just starts to push and then the wire starts to slip in the rollers of the wire feed. Your tensioner will be set just right. Another possibility is that the tip and nozzel are dirty causing it to ground when you pull the trigger and the wire touches your work. If this is the case clean both tip and nozzle. A good tip is to us a an anti spatter product. Just rememer to dip the nozzle in it every once in a while, while the nozzle is hot. A third possibility is that the liner in your lead is dirty or the wrong diameter wire for the lead, tip or the rollers is being used. Check to make sure that these items match the diameter wire you are using.
I know the response is a little long, but I hope it helps.

I don't know where you are located, so I don't have a local vendor name to recommend. However, look up motor and generator repair companies, and give them the name plate information, they will be able to provide you the slip rings.

If your in NY, Volland Electric is one such entity

why would you need to go to the lowest setting?. anyway look at the feed rollers, make sure they are the correct size for the wire, secondly check the clutch mechanism on the wire mounting centre post this might be too tight, thirdly check the linner this could be crimped.
If the set works ok on number 2 it should be ok on 1, perform the set up again, ensure the rollers are not tightend down on the wire.
lets now if the problem clears,

hi if the set cuts out after 10 /15 min on full power the thermal cut out switch is doing its job if it cuts out after 2 or 3 min it is faulty it is a bi metalic switch and is clipped on the main transformer take the wires off it and join up try the set DO NOTweld without it as you will overheat the transformer these little sets only have something like a 20% duty cycle hope this helps merlin v12

check to see if tip is correct size for the wire you are using.

Sounds like you need a tune up. Check or replace spark plugs, air filter, fuel filter, carberator, and idle linkages.

Does it even hum? If not, unplug it and remove the cover. Check around inside for fuses or loose connections. If all seems well, plug it back in and carefully test to see if power is coming to and through the switch.

The transformer has an overtempature switch the shuts the welder down when its duty cycle is exceeded. After it cools, the switch will close and the welder will run again. However, you are not supposed to use the welder until waiting an additional cooling off period as specified in you manual(~10 min.).Also you are not suppose to weld beyond the duty cycle or damage could result. Especially if done on a continuous basis.

Hi,
To get parts for your welder you'll need to have the serial number off the tag on the case. This problem could have other causes, have you:
Checked the tension on the wire spool? You ought to be able to pull the wire by hand easily.
Checked the tension setting on the pinch rollers? Too much tension can drag down the motor speed.

You could also have a bad control card depending on which model wire feeder this is.

Carl

go holbart web sight and look them up hope this helps jojogunne

Is your air compressor able to keep up with the continuous regulated air flow?
If positive air flow is not constant same pressure all the time
cutting will stop..>>

Also if your movements are to fast and or material to thick machine will behave that way..

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 ..

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