How can I improve my plasma cut quality guide?

Corrections

1. Check the nozzle first for signs of wear (gouging, oversize, or elliptical orifice)
2. Decrease the cutting speed in 5 ipm increments.
3. Decrease the standoff in 1/16 increments or 5 volts increments.
4. Increase the amperage (but do not exceed 95% of the nozzle orifice rating)

What are Pac torch electrodes made of?

The electrode is usually made of copper, but with a metal insert at the point where the arc attaches. That’s because the copper would melt too fast if the arc attached directly to it. Tungsten makes a great electrode material, so lots of electrodes have a tungsten insert.

What is a plasma cutter drag tip?

A drag tip is used on the end of your plasma cutter to cut through thin metals easily. Drag tips are great for cutting sheet metal, even at low amp rates. You can draw straight lines or follow patterns easily while dragging along the surface of your metal while having total control over how fast things move.

What polarity is used for plasma cutting?

negative polarity
The electrode has a negative polarity and the workpiece a positive polarity so that the majority of the arc energy (approximately two thirds) is used for cutting.

What all can you do with a plasma cutter?

Plasma cutting is used for all sorts of metal fabrication projects and is typically used in on-site construction or salvage yards. For designers and artists, the most common uses are in both signage and sculpture, as well as being used in decorative panels for interior projects.

Can you cut rusty bolts with a plasma cutter?

They also can be used to cut nearly anything that is metal, including steel, stainless steel, and aluminum. You can even use them to cut rusty nuts and bolts just like you would use a gas torch, only much faster and with cleaner results.

What is a plasma cutting machine?

Plasma cutting (plasma arc cutting) is a melting process in which a jet of ionised gas at temperatures above 20,000°C is used to melt and expel material from the cut. During the process, an electric arc is struck between an electrode (cathode) and the workpiece (anode).
