This dust can and will get on and coat everything in your shop. The plasma stream is vaporizing metal and the process generates a fine metal dust. The water is there to serve several purposes.

Water table - A water table is one that has water under your cutting slats (the pieces of metal the sheets your cutting sit on). If you have the though of doing this on a regular basis buy the 4x8 and save yourself a ton of headaches.

This should be a once in a great while operation. It is possible to make this happen but its has the potential to go bad in a hurry if your are not very careful and very precise.1 in off in any direction and ruin a cut. You can index or move the sheet on your table to allow this to happen. One quick note on Indexing sheets - this is where for example you have a 4x4 table and need to cut something that is 4x8. If you buy one size bigger than you think you will need your probably going to be pretty safe. When it comes to size really consider what you want to do and what you may do in the future. Unless your on a submarine I would skip this size. After a couple weeks of cutting they realize how amazing CNC Plasma cutting is and they want to make a million other things but they have a 2x2 table and are stuck. I hear so many people say I’m only going to cut these small widgets so I don't need a big machine. Its so small and easily outgrown after a very short period. I try to steer people away from the 2x2 table. Most of the cost is in the electronics, controllers, software, computer, and plasma cutter, the components that all the sizes have in common. The cost difference between sizes is relatively small. I have a lot of people ask what size table should I get? This is difficult question and you need to really think about this one. Larger industrial tables can be configured to nearly any size the customer needs. These sizes coincide with common steel sheet sizes being 4x8 and 5x10 feet. Tables Sizes - Tables for the hobby, general fabrication, and light industrial come in a few common sizes: 2x2, 4x4, 4x8, and 5x10 feet.

Lets start by breaking tables down into a few simple groups and defining some terms. Plasma tables come in all shapes and sizes and it can be difficult to tell the good from the bad just by a picture.
