According to our experience, when we talking with the customer who are going to buy a cnc plasma cutting machine the most frequently asked question is that what is the proper plasma power for my job? The maximum cutting thickness of plasma power varies according to different plasma power. So to decide what the proper plasma power is, we need to see what the maximum cutting thickness you need. CNC plasma cutter is a special machine used for cutting metal sheet. So, as long as you tell us the maximum thickness of the sheet metal you want to cut, we can suggest the proper plasma power for you. There are two plasma power source brands which are used on cnc plasma tables. One is Huayuan from China, the other is Hypertherm from USA. Here is the quality cutting capacity of both brands for your reference.

More tips on choosing plasma cnc machines

Except the plasma source power, users need to consider from these aspects:

1. Working size of plasma cutting cnc table: the working size shall be determined according to the metal sheet size of the user. Machine working size should be big enough to cut the metal sheet

2. With torch height controller (THC) or without: with torch height controller, the cnc plasma cutter tables can cut metal sheet which is unflat, the plasma gun head will automatically rise and fall as the material goes up and down; without T.H.C controller, the machine can only cut flat sheet.
