Product Summary

The AMP® Plasma 450x Cutter is a lightweight unit that features powerful inverter technology for smooth cutting. Handles almost any project you can throw at it, from mild steel to copper, brass, stainless and aluminum up to 3/8in. Cuts faster and more precise with a thinner kerf and less slag than cutting with oxy fuel. A smaller heat-affected zone also causes less warping. No gas pressure settings, flame tuning, metal preheating, or gas cylinders or refills to worry about, ever.


What’s Included

  • (1) Plasma Cutter

  • (1) 18.5ft. cable and torch lead

  • (1) 10ft. ground cable and clamp

  • (1) Additional electrodes and nozzle

Easy to Use — Ready for Action

Ready to Use, Right Out of the Box

The all-inclusive Plasma 450X comes packaged and ready to go with just about everything you need to get the job done right — including extra torch electrodes and nozzles. Just provide some shop compressed air and you’ll be off and cutting.


240 Volts of Powerful Performance

Plug into a 240V, 40A electrical circuit to deliver unbelievable cutting power and performance that goes above and beyond the capabilities of standard 120V models.


No Dangerous Cutting Gases

Unlike oxyacetylene torches, the Plasma 450X uses regular shop compressed air to create a safe, yet very effective, plasma cutting arc. No need to bring volatile cutting gases into your shop or garage.


Tough, Capable and Versatile

If It Conducts Electricity, You Can Cut It!

Whether you’re working on steel, stainless steel, aluminum, galvanized steel, copper or brass, if the material can conduct electricity with little effort, the Plasma 375 can cut it. Make clean cuts in up to 3/8 in. steel, or sever cuts in up to 1/2 in. steel.

Clean Cuts with Minimal Warping

Plasma cutting efficiently reduces heat retention in the metal. Less heat means less heat-affected area, resulting in less warping and less material damage or post-cutting cleanup.

Trigger Only Once

The built-in pilot arc feature really comes in handy when cutting items such as chain-link fences or expanded metal. No need to retrigger each time you hit an open gap of air; the pilot arc keeps the arc on, allowing you to quickly and accurately move to the next target section. The result is faster cuts PLUS less wear and tear on your electrodes and nozzles.

Performance on the Go

Enjoy the freedom of plasma cutting almost anywhere. Built-in inverter technology makes this unit a powerful, yet very lightweight, performer. The quick connect torch and ground cable provide easy setup and take-down, while a convenient carry handle encourages you to take it along with you.

Detail Work on Your Prized Possessions

If you’re looking to restore that prized old car or take care of your own body work, the excellent plasma characteristics ensure quality cuts. No matter how delicate or tough the project may be, you’ll be able to cut with confidence.
