Overview plus

It's difficult to beat the convenience of a portable plasma cutter. Keep your preferred cutting tool within reach with the CUT50D Portable Plasma Cutter. This light-weight, 50-amp machine provides heavy-duty cutting right out of the box. With 50 amps of power on tap, this portable plasma cutter can cut up to 1/2-inch thick steel plate, no problem.

A Portable Plasma Cutter — Convenience & Power

A plasma cutter is one tool that every fabricator needs in their arsenal. Save space, time, and money with PrimeWeld's 50-amp air inverter plasma cutter. It's all you need for an array of cutting applications, all in one convenient package.

The CUT50D is a MOSFET (metal–oxide–semiconductor field-effect transistor) inverter plasma cutter that weighs only 23 pounds. This portable machine is light enough to take between shop, job site, and home. Imagine bringing your plasma cutter to your friend’s to handle a little auto body and suspension work!

Cut Sensitive Sheet Metal With Ease

The lower limit output of 20 amps cuts sheet metal as thin as 22-gauge without blowing your nicely cut edges out, saving preparation time to get the workpiece prepared for welding. 

The CUT50D Air Inverter Portable Plasma Cutter can power any DIY workshop project. Durable build quality combined with innovative design make it an excellent choice. Plus, get helpful support from a knowledgeable service team whenever you need it. Bring exceptional cutting power to your shop for under $300.

High-Frequency Arc Control for Precise Cuts

This portable plasma cutter’s high-frequency arc control uses a non-pilot “touch and lift” arc start. Lift-start machines are great for drag starts and drag cutting. Just touch the torch momentarily to light the arc, then drag the torch across the surface to make your cut. Using the CUT50D plasma cutter couldn't be easier. With the torch tip so close to the metal, drag starts let you get finer, more precise cuts with your portable cutter.

Lightweight, with Dual-Voltage Input Power

PrimeWeld's CUT50D 50A Air Inverter Portable Plasma Cutter can use whatever voltage is available! This portable, lightweight machine runs on either 120 volts or 240 volts input power. It uses an adapter pigtail to enable the base 240-volt power supply to plug into 120-volt outlets. Powerful plasma cutting power at your fingertips, no matter where you find yourself.

How to Use plus

How to Use

Technique Tips

  • It is easier to pull the torch through the cut than to push it.
  • To cut thin material, reduce the amperage until you get the best quality cut.
  • Use the correct size tip orifice for the amperage being used.
  • For straight cuts, use a straight edge or cutting buggy as a guide. For circles, use a template or circle-cutting attachment.
  • Check that the front-end consumable parts of the plasma cutting torch are in good condition.
