3 vital things to consider when purchasing a Plasma Cutting Table
Most plasma cutting tables are adaptable and can do a few jobs reasonably well. However, optimum efficiency is what we’re all after, right? It is fine to have a machine that can perform well enough on most tasks you’ll need it for, but it’s better to have a machine that efficiently performs the task you need it for most (as well as some extras).
With that in mind, here is a short guide to three vital considerations when you’re purchasing a plasma cutting table.
First note of business, is to work out what you’ll primarily be using the plasma cutting table for. More specifically you should think about what thickness of metal you’ll usually be cutting on it. This makes a difference because you could end up paying more for a table with flexibility you don’t need, or you could end up saving money in the short term by buying a table that doesn’t give the flexibility you do need, and having to pay out in the future.
The Thicker the Metal the Higher the Amperage
In basic terms, the thicker the metal you cut on average the higher you want the amperage of the cutting table. Smaller tables will cut thicker pieces of metal, but not so efficiently and you won’t be left with an entirely neat cut; it increases the risk of sever cuts. You want to restrict machining your metal to a minimum to save yourself money, so buying a table with a smaller amperage might indirectly increase your costs.
Every table we offer has an optimal range of thickness and we can make sure you get the plasma cutting table that fits your needs. As a rule, optimum for 1/4” is 25 amps, 1/2” is 50-60 amps, and 1” 80 amps. You can book a demo and we can talk you through some of the specifics.
As well as thickness, speed is a vitally important element to consider. You can work this out in a very simple way, if you need a production level of speed, you want an amperage able to cut twice the thickness of metal that you will most commonly be cutting. This will ensure that your machine can cope cutting through the metal at a consistent speed.
If you want to cut 1/2” metal for long periods at a high speed, then you’ll want a machine that can handle 1” metal, to ensure the table isn’t struggling to keep up. Buying a class above, means your production can be quicker and cleaner.
Another vital thing to consider with speed and longevity is the duty cycle of the table. Duty cycle refers to the amount of time that the table can continuously cut for before requiring cooling to ensure the plasma torch doesn’t over heat. If a machine is rated to have a 70% duty cycle this will mean that table can cut continuously for 7 minutes out of 10 before it needs to stop to cool. Considering the type of work, you’re going to be doing is really important to ensure you get all you need from your plasma cutting table.
