Plasma is superheated, compressed air that ionizes to form a conductive gas. This gas conducts electricity from the torch of the plasma cutter to the work piece, through a electrode and copper nozzle ...

If you've built a custom classic truck, chances are you've had to deal with cutting metal-it may have been removing or modifying something old or installing something new. And, if you're like most ...

Can using plasma to cut your tube and pipe be a better option for your operation than a saw or laser? Quite possibly, but ...

When a person learns how to cut metal and weld they open a new world of possibilities. The past articles in this series covered the most popular methods for welding, and now we'll look at some of the ...

Plasma cutting uses hot jets of plasma to cut through a wide array of materials, especially those that are electrically conductive. With a watermelon or a steak, the results are a little less reliable ...

For consumable parts a typical shielded plasma torch has an electrode, a nozzle, and a shield. Many other torches are unshielded with an exposed nozzle and an electrode. The two consumable parts in ...

[Metal Massacre Fab Shop] has a review of a portable plasma cutter that ends up being a very good demonstration of exactly what these tools are capable of. If you’re unfamiliar with this kind of work, ...

For many four-wheelers, building our rigs is almost as much fun as driving them. There are many really unique and functional rigs built in the home shop. The adage that "real Jeeps are built, not ...

Little Shop of Physics has built a miniature plasma cutter using a pencil lead together with 4 x 9 volt batteries and a couple of clips allowing you to cut through aluminium foil. Watch the video ...

Plasma cutting – occasionally referred to as ‘plasma arc cutting’ – is a melting process that sees a high-temperature ionized gas jet used to melt the material and expel it from a cut. This ionized ...

A plasma cutter looks similar to an arc welder, but instead of joining metals, the job here is to cut through them quickly and accurately. We’ve been looking at the technical aspects so we can help ...
