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.

Rossi 220BZ Gas/Gasless Inverter Welder MIG MAG ARC Portable Welding Machine

The Rossi 220bz mig welder comes set up to use gas welding, that is with the Mig electrode connected to the positive terminal, inside the machine.
To use gasless mig wleding, the mig wire must be disconnected from the positive terminal inside the machine and reconnected to the Negative terminal - inside the machine. Open both the side coveres of the welder using a phillips screwdriver. Use a 13mm spanner to undo the hex nut holding the thick copper Mig lead to the terminal named positive, then lead it through the machine to the terminal on the oppisite side of the machine, labelled negative and screw it in place there with a 13mm hex screw. Be carefull not to bump any of the many electric parts inside the machine.
If you run the Mig welder in gasless mode with positive earth and positive elecrode it will blow the household electric fuse.
If you run the Mig welder in gasless mode with negative earth and positive electrode it will work, but the end of the Mig gun tip will get very very hot and start smoking abnormally from excessive heat.
But if you take the side covers off and rewire it (takes about 10 minutes) to negative Mig Electrode, the Mig gun tip remains cool and does not overheat. You will have to cut just one white cable tie, to get an extra inch or so of free Mig cable, so the thick copper Mig lead will reach accross to the terminal on the other side of the machine named negative. Stick the earth lead at the front in the positive terminal.
I did this on my Rossi 220bz mig welder.

Don't know where to connect shield gas to mig weld

Depending on make and model, they all should. it may just be yours needs the gas accesory kit which would have the gas solenoid, the regulator, flowmeter and hoses.

In general the the gun assembly should have a location to accept a hose connection- this connects to the output of the solenoid, the input connects to the flow meter which connects to the regulator which attaches to the tank valve. The solenoid will have 2 wres, one goes to the common terminal the other goes to the contactor lug that is normally open when machine is on, and closes when trigger is pressed.

You can transfer the gas handling pieces from another machine to yours. If need be, you can change the gun assembly as well if you do not have a hose barb on your current assembly.

The process is simple to describe, but the details can vary widely from machine to machine.

My mig welder will not make an arc

There is a small chance the transformer burned out, but more likely the switch has dirty contacts or burned out. If you turn the switch through all heat positions 2 or 3 times before you start welding in the morning, it should remedy it in the future. In the short term, spray some contact cleaner (or even WD 40 in this rare instance) into the heat selector switch and rotate it through the ranges a number of times to remove corrosion from contacts.

Will the wire arc when dragged across the ground clamp? If not- there are internal fuses in the machine and they may be loose or blown. There should be one in series with the "hot side" (the gun) of the circuit and sometimes on the ground clamp side of the circuit.

There is a small chance the transformer burned out, but more likely the switch has severely corroded or dirty contacts or the switch burned out.

216 mig no feed no fire maybe selonoid problem please help seloniod does not click

It could be just the simple problem of the trigger not working. Disconnect the trigger wires from the machine at the plug at the front of the machine. See if you can manually trigger the machine by placing a piece of bent over mig wire onto the contacts. If the machine does trigger from this then your fault is in the torch somewhere. It could be the trigger (which commonly does fault from a dusty environment) which is easily replaced by going into any welding store with the torch model number (magnum 250L), or it could possibly be that a trigger wire has broken from the torch being damaged

Your gas hose or torch could be bad or plugged. Your gas solenoid on the welder itself could be bad. Disconnect the torch gas hose at the welder and see if you have gas coming out of the welder itself.
