Plasma Cutting Tips & Tricks

Thursday, September 13th, 2012

Looking for some tips on plasma cutting? On a visit to see our friends at Cotati Speed Shop in Santa Rosa, Calif., we created a cylinder rack for welding gases. Here are a few suggestions and watch the video for more! We start by measuring out the plate size, making sure to compensate for the edge of tip. Roll the tip over and see where the plasma is going to penetrate the metal. It’s important to be comfortable when you’re plasma cutting, so don’t press down too hard on the metal. Let the tip sit on your work piece and drag, using your free hand for leverage. Before cutting, test the cut and make sure you’re able to make the cut comfortably in one move, so that it is as straight as possible. If you’re cutting a bevel, use a stand-off guide to make sure you don’t damage your tips and to get a perfect cut. When you begin cutting, start and an angle and roll the tip until it pierces the metal – this keeps the splatter from getting back into the tip.

Plasma cutting tip

Tuesday, September 27th, 2011

Before you fire up your plasma cutter, you have to set up the machine correctly for what you’re about to cut. First decide what power you have available; 110V or 220V. One common question we hear is, “Do I drag the tip or not?”

On thinner material, yes – you should drag the tip. On thicker material with the Spectrum® 375 X-TREME™ Plasma cutter, hold a slight gap to insure full capacity. Machines equipped with a drag cup should always be used in the drag position.

If you can’t cut through the material, you may be going too fast or you don’t have the machine turned up enough. If you see sparks going through the bottom side, you’re probably running at the correct speed.

Using a template when dragging makes cutting shapes easy, but remember that using and electrically conductive template can cause the arc to lose cutting strength or double arcing causing degraded parts life and poor cut quality.

If you’re cutting too slow the arc may go out which means you’re not completing the circuit.
