There are quite a few things.
1. Uses ohmic contact to sense the surface of the plate before each cut. This a very accurate method of initial height sensing that allows for proper pierce height.....which dramatically increases consumable life with any plasma torch. One bad pierce can destroy a nozzle.
2. Has the easiest to learn drawing package for cnc beginners. If you read the tutorial in the manual you can start drawing in CAD....with no experience....and be cutting parts within an hour.
3. Easily imports .dxf files.
4. Can hold a hand plasma if you want.....or you can mount a machine torch.
5. Has servo motors...not steppers.
6. Has a good warranty and great customer support. This has changed....it wasn't always this good!
7. Is the least expensive machine with servo motors , a full functioning THC with initial height sensing, and a cad drawing package.
8. Has built in diagnostics to test almost all components of machine through the PC.
9. Is available in a 4 x4 version and a 5 x 10 version.
10. Has a huge installed base of customers.
I'm sure there are other good features. I have owned a PlasmaCam for over 7 years.....just sold my first one and am installing a new right now. I will have pictures in a few days...it will have a Hypertherm Powermax45 with a machine torch.
There are a few people that knock the PlasmaCam machines due to their lightweight construction.....and due to past history where product support and warranties were almost non existent. Well the company and the machines have evolved....they are of a very clever design.....and you will be hard pressed to find PlasmaCam owners that are not happy with the product today...and there are many!
