Frequently Asked Questions
Q. Do Plasma Cutters With Built In Compressors Function The Same As Those Without?
Cutters with built in compressors have all of the functionality and usability that you find in plasma cutters that require an external air compressor. The built in compressor saves you from having to run two pieces of equipment so it makes the cutters that have the built in compressors easier to work in remote locations, and they are quieter.
All of the settings that you are accustomed to having on your plasma cutter that requires a separate air compressor will be on the cutter with the built in compressor. The only difference is you only need one machine to do the work that used to require two machines.
Q. Why Are These More Expensive Than A Normal Non-Air Compressor Plasma Cutter?
When you purchase a traditional plasma cutter you also have to purchase an air compressor to work with the unit. You have the cost of two pieces of equipment. When you purchase a plasma cutter with a built in air compressor you only have to purchase one machine. The cost of a single machine that does the work of 2 machines is slightly higher than the cost of just a cutter with no air compressor.
Q. What Does “Duty Cycle” Mean And Why Is It Important To Consider When Buying A ``Plasma Cutter?
The term duty cycle indicates the amount of time the unit can work in a specific amount of time. If you have a cutter that has a 30% duty cycle then the machine can be working for three out of each ten minute period without overheating. A duty cycle of 50% means that in a ten minute period the machine can function for five of the minutes.
Q. What Is The Cost Of Maintenance For These Machines?
These machines have relatively no maintenance costs. They are electrically powered and you do not need to change oil or filters in them. You should check cords and leads to make sure they are in good condition, but you basically do nothing else to maintain this equipment.
Plasma cutter compressors will save you both time and money. They are convenient and easy to operate so you can take them wherever you need to work.
