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.

How to Calculate three phase watts with unbalanced phase current?
You will need to determine the power per phase, and add them up to give the total power of the three-phase load. To do this, you will need to multiply the phase-voltage by the phase current by the power factor -for each phase.
Can you convert a three-phase motor to a single-phase motor?
Use only one of the legs (L1-L3), and the neutral. Some three phase circuits don't have a neutral. If that is the case, then you cannot run single phase.CommentYou don't need a neutral, providing the voltage is appropriate, you can get a single-phase supply by connecting the load between any two lines.
How do you wire a 3 phase appliance with no 3 phase supply?
There is really no way to do this short of buying a phase converter with the proper kW rating to convert your single-phase power to three-phase. This route is seldom cost-effective.There is no 'wiring method' where you can simply hook up the wires and have it work.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS. If you do this work yourself, always turn off the power at the breaker box/fuse panel BEFORE you attempt to do any work AND always use a meter or voltage indicatorto insure the circuit is, in fact, de-energized.
How do you calculate the total input current from a 3-phase power source when the current from each phase is known?
Add them upAnswerThere is no 'total' current in a three-phase system. The current flowing in each line (not 'phase') is considered separately. And you most definitely don't 'add them up'!
What is three-phase unbalanced load?
A balanced three phase load is where the current flowing in all three phases of the load are reasonably close to each other.Another answerWhen the voltage and measured current draw do not deviate by more than 2 percent under load.AnswerA balanced three-phase load is one in which each of the three loads is identical in all respects (magnitude and phase). Further to the first answer, the three line currents must not all be 'reasonably close', they must be identical -i.e. the same value and phase relationship.
How do you hook up 230V 3 phase from 480V 3phase?
If you don't know you need an electrician, you can't hook things up with 480 v kicking around, you'll get a shock. <<>> You will need a three phase step down transformer to change the voltage supply from 480 to 240.
What does the phases on a nameplate of a motor mean?
On a three phase motor, the phases give you direction for how to hook the motor up to make it spin one direction vs. the other. If you hook up such a motor blindly with all three phases, it may spin in the opposite direction you want; to fix, you swap any two of the three phase connections.
How do you Connect 3 phase water heater to single phase?
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.
Can you hook up a stove to a normal three phase socket?
If this is in your residence it is extremely unlikely you have 3-phase power. You need an electrician to make sure you don't burn down your house.
How do you run a 480 volt welder on a 230 volt hookup?
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.
If you have a spa that is 240V with 4 wires can you hook an extension cord from a 240V welder to it to see if it works if the cord only has three wires?
Well, maybe. What is the current rating on the spa circuit? What is the current rating on the welder? If the welder is larger than the outlet, then no. It must be the other way around. If the current ratings are OK, then yes. Your welder doesn't need 110V so it doesn't connext to neutral. Connect the hot leads to hot and ground to ground.
How do you hook up 3 phase to a 10 hp compressor?
First you have to have three phase power coming in. 3 phase are three hot wires working together on a syne wave. If you have 3 phase coming in, hook the three hot wires into the compresser, if it runs backwards, trade places with two of the wire and let the third one alone and you should be running.
How many monitors can you hook up to your desktop computer?
Three
How to Calculate three phase watts with unbalanced phase current?
You will need to determine the power per phase, and add them up to give the total power of the three-phase load. To do this, you will need to multiply the phase-voltage by the phase current by the power factor -for each phase.
How do you hook up 9 lead 3 phase motor?
Don't know of any three phase low voltage motors. Perhaps it's a "stepper motor". Stepper motors are typically computer controlled, with the computer pulsing different pairs of wire to cause the motor to "step".
What is the formula to get neutral current in three phase transformer where three phase cureent are given?
Neutral current is the vector sum of the phase currents. You should be able to add up the phase currents from their polar quantities.
How do you get single phase 440 from three phase 440?
You Don't. 440volt 3-phase is actually 480 volts, taking a single phase gives 277Volts single phase. To get single phase 440 you would use one leg of three phase 440/760 three phase power.
