Product Summary


Play Video

The Northern Industrial Plasma 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

Easy to Use — Ready for Action

Ready to Use, Right Out of the Box

The all-inclusive Plasma 375 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.

230 Volts of Powerful Performance

Plug into a 230V, 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 the process of using oxyacetylene torches to cut, the Plasma 375 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.

Loaded with Features

You Control the Air Pressure

Many times air compressors put out more air pressure than a plasma cutter needs or can even handle. The Plasma 375 has an adjustable on-board air regulator to prevent excessive air pressure from entering the machine and causing damage. A front panel air pressure gauge clearly indicates the pressure you've set.

The Convenience of Interchangeable Parts

The Plasma 375 includes a high-quality 18-ft. Trafimet® Torch — the same plasma torch used on other Northern Industrial Welders brand plasma cutters such as the Plasma 275 (Item #32497). If you have multiple plasma cutters, one set of parts can service both compatible units!

Keep Your Current Up to Par

A cutting current adjuster knob provides the versatility of variable settings, allowing you to choose the cutting current output you need to do the job right. Trying to cut thicker metals? Cranking your current up to a higher output setting to match your needs is a breeze.

Easy Pressure Monitoring

Keep your air pressure at the best levels for optimal cutting performance. An easy-to-view pressure light automatically turns on to warn you when the air pressure from the compressor gets too low.

Use it Anywhere

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.

Use it Anywhere
Safety Matters

Safety Matters

No More Overheating

Be it a hot day or a larger cutting project, the thermal overload protection ensures that your plasma cutter will stay safe no matter how hard you run it. A built-in thermostat prevents the unit from overheating, delaying power to the motor until the unit has sufficiently cooled. The unit also safely shuts down in over-voltage or insufficient voltage situations.

Know When You're Ready

A highly visible work indicator light mounted on the front of the unit shines brightly whenever you are cutting, so there's no mistaking that the unit is in full operating mode.

Stays Safely Grounded

To further protect the user against improper usage, the 375 Plasma Cutter requires a ground clamp to be properly secured before the unit will operate. If the ground clamp comes loose, the unit safely and immediately shuts down.
