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.
What else can I help you with?
What size wire do you need for 440 three phase welder on an eight foot run?
The wire size depends on the amperage, not the voltage. The fact that the welder runs on 440 volts does not affect the wire size! You need to ask this question instead: What size wire do you need for a three phase welder on an eight foot run if the nameplate amps are 45A?
Can you run a three phase motor with single phase generator with help of phase converter?
Terminology gets misapplied but a 3-phase converter produces a 3 phase supply from a single phase supply. The only proviso is that generator, converter and motor are all suitably rated and compatible.
Will a 240v 3 phase welder run better than 240v 1 phase?
Yes, because you will be able to maintain current flow between phases.
How do you install a phase converter?
If you want to install a phase converter, there are specific directions that you must follow. First, shut off the electricity to the device. Next, install the converter in a dry and vibration free environment. Install a ground cable that will run from the device to the converter.
What size motor do you need to run a compressor 2 stage 80 gallon tank i have a 3 phase on it and want to change motor?
You probably need a 5hp or 7hp motor. Look for HP rating o the 3 phase motor and select the same for single phase. 3 phase has same power but is more efficient at electricity use. Also consider a 3 phase converter. It allows a 3 phase motor to run on single phase service.

Where would I find phase converter equipment being used?
Phase converter equipment can be used in a generator. They can help provide electric power. Phase converter equipment is used to run computers, pumps, etc. There is quite a bit of information online at www.phase-a-matic.com.

You have one hp three phase motor where as available power supply is only single phase how can you run this motor?
You will need to install a phase converter or change the motor to single phase. You can find a licensed electrician at www.contraxtor.com
Can you plug a 2 phase welder on a 3 phase plug?
No. Three phase service is something that you would need to request from your power company. You'd need to not only have service, you also need to have an electrician run 3 phase service into your home.
Phase Converter Shopping Guide?
A phase converter is a rotating machine, quite similar to a motor. The machine converts single-phase utility power into 3-phase electricity for use by 3-phase equipment. We use a phase converter where 3-phase utility is unavailable, or when it is too expensive for us to install. A properly sized and purposefully chosen phase converter is an economical option that will operate any load as well as the utility 3-phase will, and a high-quality phase converter provides an ample lifespan. The primary decision the consumer must make is the choice between a rotary or a static phase converter. Rotary 3-phase converters are the most reliable type of converter, and they are the most flexible. They produce true 3-phase power, and thus they operated any type of load or combination of motors. Static 3-phase converters do not generate true 3-phase power, and are very similar to an electric rope starter. Once the motor is started, static converters cannot balance the load between the three legs. Therefore, using a static phase converter, the motor is never able to develop full horsepower. However, they are suitable for heaters, rectifier loads and single motor, small horsepower applications. The benefit of the static 3-phase converter is that it starts quickly, and it is substantially less expensive than a rotary phase converter. Therefore, if for your application, the motor can run at 70% of nameplate horsepower, and you start it infrequently, a static phase converter is a great choice. By infrequent, we mean less than four starts per hour. Customers must know that there are no industry standards that apply to phase converters. This means a couple of things for the consumer. One, the price between similar models can vary drastically. Two, low quality phase converters are far more trouble than they are worth. Make it a point to research phase converter brands, and pay the premium, if necessary, in order to get a high quality model of the type you require. In addition, never compare phase converters solely on the nameplate horsepower rating. Ask for the NEMA frame size, and then compare phase converters of equal frame size. Marketing often suggests that you can achieve similar/same output from a small frame size. This is impossible, so keep that in mind, and ignore the clever marketing.
What is the simplest way to run a 3 phase 380 V motor of about 1 KW directly on 220 V single phase supply without resorting to rewinding or frequency converters?
You cannot run a three phase motor on single phase power. You'll burn the motor up within minutes. By the way, I've never seen or heard of a 380 volt motor. Do you mean a 480 volt motor? If so, the only way you can power it is with the correct full voltage and a 3 phase power supply.
Can a generator run an arch welder?
yes
How to compute the load of your phase converter?
A lot of people don’t understand the main function of this small but very useful device called a phase converter. This device was made for the purpose of changing single electrical power into a multiphase electrical power. There are different types of phase converters; some change electric power from single to double, but the most common one is the one which produces three phases of electrical power coming from just a single source. It may sound like a complex and mind blowing thing to do, but yes, physics has made it possible. There are a lot of ready-made phase converters on the market, but aside from the fact that they may be costly, there is simply a sense of pride when you can create one of your own. Oftentimes people tend to step back when trying to create electrical equipment, but little do they know, it’s not as hard as you think it is. Before you can even start creating a converter on your own, you must first understand the main thing, which is the amount of horse power needed to run your converter. To have a better understanding, follow through with these steps: * The first thing that you must do is to calculate the horsepower that is needed to run your phase converter. You must decide on the amount of horsepower you want your converter to run. Let’s say you decided 8Hp. Reminder: It is advisable not to exceed 80% of the entire rated load which is to be used by the converter. This is to ensure your converter will be running safely. * Now that you are aware of the horsepower you want your rotary phase to run, then you now can proceed to calculating it. For example, the amount of horsepower to be utilized is 8hp. Since it should not exceed 80% of 8hp, the result would be that the converter would only run 6.4hp. So, your converter is utilizing 8Hp but the converter is only running at the amount of 6.4 Hp. Now that you understand the amount of horsepower needed, you can now proceed with connecting the rotary phase converter. Be sure to use a 240volt power when terminating your converter.
