To answer this question a voltage is needed.

The generator should be about ¾ hp.
The formula which are needed for making of a single phase transformeri.e o/p voltage,watt,current,turn,core size,coil number,bobin size etc
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.
A 30 amp disconnect will be suffice for the project. If the project is single phase then a two pole will be used and likewise if the project is three phase then a three pole disconnect will be used.

This is a voltage drop to establish wire size question. For a correct answer to this question two values are needed. One value needed is the voltage and the other is whether it is three phase or a single phase installation.

Fuse SizesThe Amperage ratings [sizing] of fuses [and circuit breakers] is determined by the SIZE of the conductors [wires] in the circuit which they serve.The size of the wires is determined by the maximum expected current [measured in Amperes (Amps) or Milliamps (mA] needed by the electrical devices "fed" by the circuit.Therefore, the answer to your question is that there are many different "size" fuses which range in Amperage from thousandths of an Amp to hundreds of Amps.

The size of conductor needed will be a #14. It should be copper and have an insulation factor of 90 degrees C. The fact that it is a three phase load does not enter into the calculation of the wire size.

It takes the size it needs.
