maybe 10 amperes
No, the wire will overheat.
A #8 aluminium wire with an insulation factor of 90 degrees C is rated at 45 amps.
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.
Yes - very much so. Steel is an excellent conductor of electricity. Wood on the other hand is a very poor conductor.
No, it is not safe to plug a 120v 20 amp welder into a 240v 40 amp outlet. The voltage difference is too high and could damage the welder. It is important to match the voltage and amperage of the welder with the corresponding outlet.
When you refer to a 200 amp welder you are talking about the output side of the welder. What you have to do is find out what the input voltage and current of the welder is to calculate the size of a generator needed to operate the welder.
no
No, you should not run a 15 amp MIG welder on a 10 amp circuit. The welder requires a 15 amp circuit to operate safely and effectively. Running it on a lower amperage circuit can result in overheating, tripping the circuit breaker, or damaging the welder. It's important to use the appropriate power source for your welding equipment to prevent accidents and equipment damage.

The unit of current flow is AMP.
The average home built today has a 200 Amp service.
12 volt is what you need. You can use either a 136 or 140 amp, makes no real difference.

To install a 50 amp welder receptacle in a workshop, you will need a dedicated 50 amp circuit breaker, appropriate gauge wiring (typically 6-gauge for a 50 amp circuit), a NEMA 6-50R receptacle, and proper grounding. It is important to follow local electrical codes and regulations when installing the receptacle to ensure safety and compliance.
