60 Hertz is the frequency that the welder should be connected to, to work as it is designed to.
Easy as one,two and three. There are four primary wires coming from you service panel.(provided you have three phase service) you can check by looking at the weather head on the roof. if it has three wires you have single phase but if it has four then you have three phase. the hot wires will be black,red and brown. the neutral will be white or green. the welder should have a manual that will give you the lead phase wire(most likely black to black) the other two hot wires can hook to any other hot wire. The neutral goes to the white or green and posts to the panel. If the welder has a switching power supply then you must have a three phase converter.
It shouldn't. Check the nameplate for input amperage of the machine. Your #6 wire is good for 60 amps. If the nameplate amperage is below 60 amps then you are good to go.

Yes, there is a difference between single phase and three phase circuits.

One is just as safe as the other. The deciding factor here is what supply voltage do you have at your establishment to operate the welder a single phase or three phase service.
Most 3-phase welders cannot be made to function on single-phase power. If your welder is an inverter type, such as a Miller Dynasty or Lincoln Invertec, then it may have a single-phase mode with reduced current output. You would have to download the manual for your particular welder. If it is an older transformer (big and very heavy), then you're probably out of options here.
in single phase inverter we use two chopper the ratio of output ac to the ratio of input dc
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.
The only benefit is you don't have to pay for a three phase service for just one motor.
Absolutely, you will have voltage drop, maybe enough voltage drop that the welder will not work <<>> To do a voltage drop calculation for the 200 foot cable the input amperage of the welder needs to be stated. At a maximum distance of 201 feet and limiting the voltage drop to 3% or less, a #6 copper conductor can deliver 37 amps on a 220 volt system. Check the nameplate on the welder to see if it falls withing the range of 37 amps input amperage. Do not use the welders output amperage.
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.
Depending on the amount of money you want to spend to make this happen there is a device on the market called a VFD ( Variable Frequency Drive). On the three phase input terminals you apply your single phase voltage. On the output terminals you connect your three phase load. When run in this configuration there is an internal switch that has to be changed to let the VFD know that it should be looking for only two lines on the input to be hot. Other wise the VFD thinks that there is a line loss on the three phase input
A single phase half wave rectifier outputs ripple the same frequency as the input. A single phase full wave rectifier outputs ripple fundamental twice the input frequency (assuming balanced recitfiers). A three phase full wave rectifier outputs ripple fundamental six times the input frequency. So 50 Hz input would yield 300 Hz ripple. See Sources and Related Links for more information.
The maximum single phase HP motor listed in the CEC is 10 HP. At 115 volts 100 amps and 230 volts 50 amps.
The physical internal windings between single phase and three phase motors makes this an impossibility That being said money can make anything happen.

Other wise the VFD thinks that there is a line loss on the three phase input terminals and the unit will not start.
