NO!
If you're running a 40 amp circuit you must use 8AWG wire. If you attempt to use anything smaller you run a significant risk of burning your house down.
If you are unfamiliar with wiring regulations and practices, contact a qualified electrician to wire the circuit for you.
That would be a 40 amp 220v circuit. Circuit breaker is 40 amps and wire is 8 awg. Should use solid copper wire. Follow oven installation instructions.
If you need a 220v circuit at only 15 or 20 amps: Get a new breaker to replace your 110v single pole breaker with a 220v double pole breaker. (You cannot exceed the original breaker's amperage rating unless you also replace the wire with a larger size). Shut off the panel's main breaker (the wires coming into the main breaker will remain hot, so don't touch them.) Remove the old 110v circuit's neutral (white) from the neutral bus bar in your distribution panel. Remove the old 110v circuit's hot (black) from the old 110v breaker. Remove the old 110v breaker. Install the new 220v breaker in place of the old breaker. (This may require you to rearrange some breakers if the old breaker was in between others) Reconnect the black wire to one terminal of the 220v breaker, and reconnect the white wire to the other terminal. Turn on the main breaker, and your new 220v breaker. Before you do this, be sure where the actual circuit goes. Changing 110v to 220v if the circuit is feeding regular 110v receptacles will cause damage to devices plugged into them. Be sure you remove all 110v devices (receptacles) from the circuit before converting it. If you need a 220v circuit for a dryer or other large appliance, your existing wiring will not be sufficient to do the above. You will need to install a new breaker and wiring. For this task, you should consult a professional electrician.
Wire size depends on amps. Use #10 for 30a. #8 for 40 or 50a. #6 for 60a.
6ga should be used. It might not be against codes where you are,and you might have a 50amp installed for something that only uses 40amp, but it should be done right, and 6ga should be used off of a 50amp breaker.
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.
that depends on the size of the welder. some welders can be used with a 110V outlet and others need a 220V. the size of the welder is the decider on that. Tech Ed Ted
Technically no. In the USA the NFPA electrical code requires a separate circuit for each large appliance receptacle- there are a few exceptions (such as a heater and AC on same circuit) - I don't think the welder is one of the exceptions. In practice, as long as only one receptacle is used at a time, it will work fine Make sure that the wire size is correct for the current (amp) draw. This is taken off of the welder nameplate. Size the breaker to protect the wire size. If more that one welder gets plugged in the breaker will trip.
If the welder does not list the input amperage, jyou can always refer back to the math that you learned in school. A simple algebraic formula will help you figure out the amperage: Amps * Volts = Watts Since you already know the Volts (use 240 for calculation), you should be able to calculate the amperage that is used by the welder. Up to about 12 Amps, use a 15 amp breaker and 14 AWG wire. Up to about 16 Amps, use a 20 amp breaker and a 12 AWG wire. Up to about 24 Amps, use a 30 amp breaker and a 10 AWG wire. You should have a qualified electrical professional perform any wiring changes if you do not have an adequate circuit already available to where you will be using the welder.
Electrical range is usually 220V and requires at least a 40A breaker. In a three wire configuration, the white power carries 110V, the black wire carries 220V and the green wire is the ground. A four wire configuration has an additional wire that is neutral.
No, the wire will overheat.

6ga should be used. It might not be against codes where you are,and you might have a 50amp installed for something that only uses 40amp, but it should be done right, and 6ga should be used off of a 50amp breaker.
No, only one GFCI per circuit.
The wire feed welder is a MIG welder.
It should take a two pole (220V) 50 amp breaker and matching plug wired with # 8 or # 6 gauge wire. Check your manual.
