Plasme Cutter Cutting

What is plasma? Plasma is the 4th state of matter (solids, liquids, gasses, and plasma)! Basically, it's a gas which has been heated to such a high temperature, it's no longer a gas – it's plasma. This plasma gas is passed through an electric current and ionized, making it electrically conductive. Being conductive, it's attracted to the workpiece where the metal to be cut is melted and blown away by the superheated plasma gas. The result is a narrow, extremely high-energy cutting arc which, with laser-like precision, slices through metal as quickly and easily as a hot knife through butter. Hands down, plasma cutting is the fastest, easiest way to cut through any material that conducts electricity. There's no contest . . . and no heat distortion!

Plasma cutting technology has been around for a while. Until recently, plasma cutters were found only in heavy industrial and specialized manufacturing applications. Now, HTP® offers state-of-the art equipment that is affordable and can be used virtually anywhere.
Take the MicroCut® 301, for example. This handy, durable cutter operates on 220 volts and only weighs 14 lbs. It's an affordable, yet powerful (cuts 5/16" steel @ 14"/min), 220 volt machine in a compact, go-anywhere package.

Or how about our MicroCut 600? This machine brings inverter technology home in 40 amp unit that cuts up to ½" at 5"/min quickly and easily.

Now, plasma cutters can be used by fabricators, muffler shops, street rodders, farmers, race car builders, and even sophisticated home handymen. Anyone who wants to cut, shape, modify or just get metal out of the way will find that an HTP plasma cutter is the ideal tool for the job. You can always count on HTP for the right machine for your application . . . at the right price.
