Yes. With SOME, you may need a motor-generator set, or an inverter, to convert the single-phase power to three-phase power....
Some more modern 3-phase welders will operate directly on single-phase, because they're inverter-type units already.
Many 'classic' transformer-based industrial welders can be made to operate easily off single phase power, at full output using the "Haas-Kamp Conversion". Do a web-search for Haas-Kamp and your welder's brand and model- if it's a popular welder, someone has probably already done it.
In most three phase devices, they cannot be converted to single phase operation.

You could use a motor/generator set, but it would be expensive and potentially non-economical.
You cannot, unless the welder can be wired for 230 volts. Often welders may be wired for different voltages.... Only a qualified electrician should work on such a setup.
This can not be done. A single phase supply of 230 volts can be used from a 415 volt three phase wye system but not the other way around
There in no quick and inexpensive way of doing this conversion. A transformer would have to be used and this type of winding is not common. 277 volts is the wye voltage of a three phase 480 volt system.
No. The voltage rating needs to be 600 volts for 480 volt power.
No, that is too much.
No, the voltage difference is too much. A 570 volt motor falls in the 600 volt range which is separate from the 480 volt range of three phase systems.
The conductor for H2 connection on a 480 volt wire transformer should be marked:
No, you will not obtain 230 volts. From a wye connected three phase 480 volt supply, 277 volts can be obtained from one phase leg and the neutral on the wye connection. 480 volts/1.73 (sq. root of 3) = 277 volts.
Depends on length. The more length, the more resistance.

It is: 230+250 = 480
Can I run 480 volt , 60 HZ motor at a 380 volt , 60 Hz system?
Yes 480 volt electric wiring can be run in emt conduit.
480 volts and 60ohm impedence current = volt/impedence current=480/60 current=8ampeares
No. The voltage rating needs to be 600 volts for 480 volt power.
No, that is too much.
No, the voltage difference is too much. A 570 volt motor falls in the 600 volt range which is separate from the 480 volt range of three phase systems.
Across a 480 volt three phase system, 480 volts should appear across L1 and L2, L2 and L3 and L3 and L1.
Inspect all motor labels and see if they are dual voltage motors. If they are, they should have a label on them telling you how to convert the motors for 480 volt. This is a relative simple task. Converting to 480 volts will lower the motor current to half of the 230 volt rating, so you will have to change the overload heaters in the individual motor starters. You need to do this to protect the motors in case of overloading. Last the control transformer will need to be reconnected for 480 volt.
