This Forney Plasma Cutter operates on 120V, 20A so it can be plugged in just about anywhere you need. However, this lower voltage and amperages translates to thinner max cut thicknesses.
This machine will cut 1/8″ and will sever up to 1/4″ metal all with a decent cut speed around 20 inches per minute (IPM). The Foreny 317 250 P+ incorporates their drag torch technology, which in our tests, did allow us more precise cuts by allowing to drag the torch directly across the metal surface as compared to needing to hover a bit above the metal.
This drag capability can be beneficial for those new to plasma cutting, but honestly, won’t have much of an impact if you have any previous experience with other types of plasma cutters.
In our testing, the Foreny 317 250 P+ seemed to have a bit slower ignition. At times, it took about 1-2 seconds from pulling the trigger until it ignited. Now depending on your needs, this may or may not be an issue. If you are doing lots of long cuts, then no real biggie, however, if you are doing lots of little cuts with lots of starts and stops, this will probably frustrate you.
Overall, the Forney 317 was a little bit slower in cutting through 1/8″ steel as compared to some of the other units we reviewed in this article. However, this means there is a trade off. The Forney 317 is almost $200-$400 cheaper than other models here but it does include a compressor, so if price is a big deal, this unit could be a good option for your tasks.

How do you choose the best plasma cutter?
All the products reviewed above are good options. To make an informed decision, there are several factors to consider when looking for the best plasma cutter.
What is your electric output requirement?
When looking for a plasma cutter, the type of electrical service you have in your work shop or job site is an important factor to consider. Do you have 110v or 220v? Each plasma cutter has its electricity requirements and several models can handle both.
So, before you choose any model make sure that electrical service offered in your shop matches the product’s voltage and amperage. Otherwise, you won’t be able to use it in your location.
Do you need portability or will it just be in the shop?
Portability is also an important factor. If you are taking the cutter from one work site to another, then you have to buy a product that is flexible and has features such as a shoulder strap, handles made for easy carriage, and/or long cables. But if you do not plan to carry it from one place to another, then you can disregard these portability features.
What is the duty cycle needed?
The duty cycle of a particular unit is the amount of time in an hour the cutter can safely operate without the torch or unit overheating or shutting down. This is generally expressed as a percentage and determined by how much amperage the unit draws. A lower percentage means the unit can run in short periods while a larger percentage means the unit can run for more time.
What type of materials will you cut and what thickness?
The best plasma cutter can cut particular types of materials and metals of varying thickness. There are some that can cut any conductive metal such as stainless steel, alloy steel, aluminum or copper but the thickness of the metal they can cut also differs. So, you should consider the type of metal and thickness of metal you will be cutting before you make a choice.
What is your budget?
Your budget is another important factor to consider. After all, it is your hard earned money and we all know money doesn’t grow on trees! There is the tendency to think that quality cutting machines are expensive. Yes, a good number of them are expensive, but if you shop around, you will find excellent bargains on quality products. And who doesn’t want a high quality machine at an awesome price?
What are your cutting ability and performance requirements?
As a rule of the thumb, it is important that you choose a product with impressive cutting performance, a product that offers precise, smooth, and no slag or dross cutting. With such a tool, you will be able to obtain a perfect cut which means less clean up of dross and/or top spatter. Because machines have different amperage’s, they can cut differing thicknesses of metal. Some lower amp units can only cut up to 1/4″ while some higher amp cutters can cut up to 1″ or more.
Do you need a compressor or an air filtration system?
Don’t you hate it when your new plasma cutter arrives and then you find out you need one more thing before you can use it? I know I do.
Some units come with built-in compressors, while some don’t. Most don’t have this, so make sure you have an external compressor that is powerful enough. We recommend the Powermate Vx 80-Gallon Electric Air Compressor.
You will also need to make sure your air compressor meets or exceeds the recommendation of the manufacturer and this one meets any of the requirements for the plasma cutters we review on this site.
Dust, dirt, oil, and moisture are the mortal enemies in compressed air systems. It is no different with plasma cutters. Often, basic filtration systems come with the cutter, however the quality of your air compressor and filter still play a vital role.
Humidity in the air is another issue since this condenses into moisture when pressurized and further condenses as it releases from the compressor. So you will also need a desiccant filtration system to remove the extra moisture and particulates that are in the compressed air.
We recommend the Sharpe 6760 DryAire Dessicant Air Filter System. While filtration systems are expensive, they can make a difference between an good cut and a bad cut. Make sure to replace the filters periodically, otherwise, your cuts won’t be as clean and you’ll be burning through consumables more quickly.
What about consumables?
Consumables are the cutting parts that will wear down with use and need replacing. Depending on your usage patterns, you will eventually need to replace them. The shield, retaining cap, nozzle, electrode and swirl ring are all considered consumables.
For more information check out this excellent article on consumables. Some of these parts, such as the electrode and nozzle, will need to replacing more often. So make sure to take the cost of consumables into account when purchasing a plasma cutter.
Many shudder at the thought of spending $1500+ to get the best plasma cutter and then spend 3x as much in consumables over the life of their “bargain” machine.
Will you be free-handing or using on a CNC table?
Some units come with Computer Numerical Control (CNC) connections or interfaces while others are only used for free-hand cutting. So ask yourself, are you planning on hooking your new plasma cutter up to your CNC table or not? Those with CNC interfaces may include a free-hand torch and the CNC torch would be an extra cost.
The above factors will determine the product that will meet your requirements. This is because the various products have different specifications to suit different needs. Of course, you should buy a product that will meet your requirements and cutting needs.
A plasma cutter is an important tool for any person working with metal. It is a bewildering prospect to select a piece of equipment that is new to you with so many plasma cutter brands and models to choose from. They come in many models, sizes and amperages. If you answered all the questions above, you will end up with the best plasma cutter that is right for you!
