Evaluating different models of plasma cutters
Plasma cutters utilize an electrically powered stream of superheated ionized gas—a plasma—to achieve localized thermal cutting action by generating a focused arc that melts and blows away metal.…

newest firstIntroduction to the hobby plasma cutter
A plasma cutter generates an extremely hot, superheated stream of gas—the plasma arc—by passing high electrical current through a constricted gas stream; this focused heat is what rapidly melts and bl…
Sizing your plasma cutter by required amperage
If you are trying to cut a thick plate of mild steel at a high amperage—say, above 30 amperes—you must size your plasma cutter's air supply inlet and torch consumables not just for raw power, but spec…
Guidelines for choosing a commercial plasma cutter
If you are consistently fabricating structural steel parts up to 1/2 inch thick at a job site, do not select a model rated only for light duty; you must opt for a machine with robust power output and …
Selecting a CNC plasma cutter table for precision work
For achieving true precision with CNC plasma cutting, do not prioritize simple cost savings; instead, focus your selection entirely on a table that provides exceptional vertical rigidity and flatness …
Value considerations when buying a plasma cutter
"Does a plasma cutter cut aluminum?"—this is the question every shop owner asks, and the answer is complex because it depends entirely on the specific setup and current draw. In short, yes, plasma cut…
Selecting a powerful plasma cutter for heavy duty work
To determine if a plasma cutter is suitable for heavy duty work, you must first assess your required amperage capacity against the thickness of the material; simply having high voltage does not guaran…
Choosing a portable plasma cutting unit for projects
A portable plasma cutter uses electricity to generate a superheated, high-velocity gas stream—the plasma—that acts as a highly directional thermal beam capable of cutting through various metals with r…
