What breaker do you use for 10-2 wire?
Assuming a 120V circuit then a 30A Single Pole. For a 240V circuit an 30A two pole. Of course anything smaller that a 30A is acceptable. 30A is the maximum allowed.
What is the amp rating for a 3 wire?
The amperage rating of any wire or conductor is determined by its size or gauge. It has nothing to do with whether it is a two, three or four conductor wire. For example, in basic residential wiring, a 14 gauge wire is rated at 15 amps, a 12 gauge wire is rated at 20 amps, a # 10 is rated for 30A and so forth.
How do I wire a single phase 120 amp 230 volt flux and mig welder to a 200 amp panel?
It is very likely that the 120A current you quote is the output current. Check your Welder Box and look at the input current. It is likely around 30 Amps. To wire a 30A circuit you will need 10 gauge wire and it is likely 3 conductots + ground. You will need a 230V Breaker. Connect the black and red wires from the 10 gauge cable to the breaker, white wire to neutral and ground to ground.
Can a 30A dedicated circuit for a heater have the heater removed and the circuit used for lighting?
Yes provided the voltage is compatible.
Can you connect a 14 gauge extension cord to a 12 gauge extension cord?
Yes, as long as the fuse or circuit breaker is rated for the smallest wire in the circuit, which in this case appears to be the 14 guage. Suppose the 14 guage is rated for 15 amps and the the 12 guage is rated for 20, and there is a 20-amp breaker on the circuit. Now suppose you have a short that draws 18 amps. The 14 guage wire will burn and catch fire, yet the breaker will not trip. That could be dangerous.

How do you upgrade the service from a 120V 100A circuit breaker to 240V 30A for appliances like ovens and dryers?
Have an electrician wire you a proper line for the appliance. You were just kidding about the 100A, right? 10, or 20amp, not 100.
What size wire for a welding extension cord 220v 50 amps?
Wire size depends on amps. Use #10 for 30a. #8 for 40 or 50a. #6 for 60a.
How do you upgrade from 120V 15A to 120V 20A or from 240V 20A to 240V 30A?
You have to replace the wire (as you are increasing the current capacity), the outlet, and the breaker. Essentially you have to remove the old circuit and put in a new one. You can't reuse parts of the old circuit as you are increasing the current capacity and they would be underrated.

Will a 20A 240V breaker be sufficient for a 240V 22A input welder or do you need to go to a 30A?
It would have to be a 30 amp breaker to use the full power of the welder. I'd say go with the 30A. The general rule is that your planned load should only be 80% of the circuit capacity. That means a 30A circuit should have a maximum load of of (30*0.8) = 24A. With the 30 amp breaker you must have at least #10 wires feeding the circuit.
Can you safely change a 30 amp breaker to 20 amps?
No, this is not a recommended procedure. The breakers main job is to protect the wire that is connected to it. A 20A breaker will have a #12 wire (rated 20A) connected to it. A 30A breaker will have a #10 wire (rated 30A) connected to it. As you can see if you use a 30A breaker on a #12 wire you could overload the wire by 10 amps. I have seen an incident where the insulation has melted off of an overloaded wire, the wire short out and a fire start before the bigger size breaker tripped. DON'T DO IT.
How many amps 10 gauge wire?
The NEC limits the overcurrent protection of #10 copper to 30A. This means that that a continuous load supplied by the #10 cannot exceed 24A unless the breaker is rated for 100% continuous duty. Don't forget to apply any derating factors as required in table 310.16 of the NEC. For derating you can use the appropriate temperature rating column i.e. 90 deg for THHN dry location but in no case can you exceed 30A. It depends upon What type of wire and how that wire is being run. Standard ratings for residential wiring is a maximum of 30 amps for a #10 wire. To get technical, I think the maximum amperage of #10 wire run enclosed (like in metal conduit) is 33 amps. Most building inspectors will go by the 30 amp rule. 10 copper wire will hold 30 amps /we use this size wire for electrical dryers. For aluminum wiring the maximum loading is lower. 10 gauge aluminum hold 25 AMPS.
