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.

What size circuit breaker is needed for a 90 amp spot welder?
AWG #4 copper.
What size circuit breaker is needed for a 220 volt welder?
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 JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
What size of electrical wire needed for 100A circuit breaker?
#2 copper
How many amps breaker is needed for a 400 watt heater?
A 400 watt heater can safely be used on a 15 amp circuit. The size breaker needed for a circuit is determined by the size of the wiring in that circuit. AWG #14 wire requires a 15 amp breaker. AWG # 12 wire requires a 20 amp breaker.
What size circuit breaker is needed for a 300 watt bulb?
A 15 amp circuit breaker will handle this situation very well. The smallest home breaker is rated at 15 amp.
What size circuit breaker is needed for a 90 amp spot welder?
AWG #4 copper.
What size wire for a 40 amp breaker to a welder?
Us 8 AWG for a 40 amp circuit.

What is the maximum wire size needed for a typical branch circuit that is protected with a 20-amp circuit breaker?
I think you mean either what is the correct size or minimum wire size needed when a branch circuit is protected by a 20 A breaker. The size is 12 American Wire gauge (AWG). 14 AWG is used for 15 A circuit and 10 AWG for a 30 A breaker. The lower the gauge the larger the cross-section of the wire.
Can you install two 220v receptacles for a welder in two different areas of your shop on the same circuit?
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.
When installing a circuit breaker do you size the breaker to correct wire size or the device its controlling?
The wire!! The breaker is there to protect the wiring not the device plugged into the circuit.
Is 60 amp breaker good for 225 stick welder?
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.
What size amp circuit breaker should be used for a home entertainment system?
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.
Installing a 120volt appliance what breaker is needed at the electric box?
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.
