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.
The proper ampere rating of a circuit breaker for an electric arc welder depends on the arc welder. Each is different. Look at the nameplate on the arc welder and choose the circuit breaker and wiring accordingly.
The other welder will also fail.
That depends on the size of the welder. A 240 V welder that is recommended to operate on a 30 Amp circuit should be wired with a 10 AWG wire.
Yes, but it may draw too much current for the circuit. If it's a 15 amp circuit and the welder draws 17 amps, it won't work. Voltage is only a part of the puzzle.
I think Certified welder learn from the books and get certificate. But Qualified welders learn from the practical knowlege then they qualify the field.
AWG #4 copper.
Simple answer is yes. But you need to first determine if your breaker can handle it, not just because you have an empty slot. You have to total up amps being used and check rating for your box. If it can handle it then it is a sinch to install
Us 8 AWG for a 40 amp circuit.
No. My cousin brother works in an inverter company as the MD. Welder is technically different term it does not convert form of electricity.
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.
