The size of the circuit breaker and the wire that will feed the welder is based on the amperage that is needed by the welder. The voltage only explains what the insulation factor of the wire should be.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.
IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB
SAFELY AND COMPETENTLY
REFER THIS WORK TO QUALIFIED PROFESSIONALS.
Check the input current rating on the welder. The output current rating of 190amp will not tell you the maximum current draw from the AC supply. There is typically a transformer inside the welder which bumps up the supply current to the desired duty cycle.
AWG #4 copper.

A 15 amp circuit breaker will handle this situation very well. The smallest home breaker is rated at 15 amp.
The 225 amps is the secondary output amperage. Look on the machines nameplate to find the input amperage. It is that amperage that is needed to size the feed wire and there the breaker size. When you find that amperage you may want to re question the breaker size.
When installing a circuit breaker, you size the breaker based on the wire size. The breaker should be matched to the ampacity of the wire to ensure proper protection against overloads and short circuits. The device being controlled by the breaker is not a determining factor in sizing the breaker.
Need to know what the wattage or the amperage is of the appliance. The load amperage is what governs the wire size and the breaker to protect the circuit.
You use the correct size breaker depending on the size wire in the circuit. If the circuit is wired with AWG #12 wire use a 20 amp breaker. If it is wired with AWG #14 wire then use a 15 amp breaker.

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.

To answer this question a voltage value must be given. Circuit breakers protect the conductors that feed the load. The lower the voltage value, the higher the current value, hence a larger the wire size is needed and therefore larger the breaker size for the circuit. In reverse the higher the voltage value, the lower the current value, hence a smaller the wire size can be used therefore smaller the breaker size for the circuit.

Branch circuits are protected by the circuit breaker found in the electrical panel. Each circuit should have its one breaker. The breaker should be rated to protect the insulation of the wire, so you can determine the breaker size based on the circuit conductor size Example #14-2 should be protected by a 15 amp breaker
A #8 aluminium wire with an insulation factor of 90 degrees C is rated at 45 amps.
Add up your amps to calculate your breaker size. Add up your loads (amps), divide by 0.8, and choose that size breaker. If that number does not correspond to a standard size breaker you go to the next higher standard size breaker.
maybe 10 amperes
From the nameplate on the welder you find the amperage that the welder draws at the three phase voltage that you are going to use. This amperage is used to size the phase converter. This amperage is also used to size the breaker that will feed the phase converter and wire size for the installation.
