Yes, you might be able to use your own plasma machine as long as there is a way to connect your system to our plasma controller for a 50:1 voltage reading and torch control. Some of the systems in the marketplace were never designed to operate with a CNC plasma table. You can use your own computer if it is a newer more powerful system. The CAD/CAM/CNC software is very powerful and requires good computing speeds.

Both systems work well for fume control on CNC plasma tables. There are a few things to consider when making your choice. If you are using a high-def plasma like a Hypertherm XPR or Kjellberg Smart Focus, you will get slightly better edge cut quality with downdraft. Water beds are dirtier and require a little more maintenance, but will help cool your parts, save you money in electric and HVAC cost, and will not effect any conditioned air in your shop. Downdraft beds are easier to maintain, collect dropped parts, and are cleaner vs. a waterbed, but will use electricity and take a little more work to get set up because of the ducting. If you are cutting a lot of aluminum with a waterbed, be careful. Cutting aluminum on top of water created hydrogen gas and can be explosive. Make sure you lower your water level or use a water additive that helps eliminate hydrogen gas prior to cutting.

Typically an air plasma will need a minimum constant airflow of 85 psi while cutting. A high-def plasma requires around 110 -115 psi. The most important thing to keep in mind when setting up your shop air for plasma cutting is to make sure it is dry. Clean, dry air is a key component to good cut quality. The cleaner and dryer, the better. Most people use a desiccant air dryer, other use a refrigerated air dryer, and some use a combination of both. If you are in an area that is already dry, a desiccant air dyer should be fine. If you are in a humid environment, a refrigerated air dryer is best. If you are in a very humid area, we recommend you use a combination of both air drying systems.

Most on-site service calls are caused by improper maintenance. Each plasma system should have a routine maintenance plan to keep the system running as long and reliably as possible. Besides the recommended routine maintenance, you should be checking the following items each day before your first cut. Make sure nothing is blocking or can collide with the bridge during its movements. Check that nothing is clogging or pinching the cable track so it is not damaged while moving. Check gas pressure to ensure you have a good minimum required constant flow. Check the edge of the table to make sure there are no leaks or loose metal pieces Make sure you have clean, dry air. Check the torch lead and wiring near the head to make sure there is no risk of it getting caught. Check your consumables and ensure that the correct consumables are installed for the intended use.
