Should plasma cutter tip touch the metal?
Be careful to not touch the plasma cutter to the metal as this may fuse the cutting tip to the metal and may cause the cutter to go out; using ‘drag cups’ or a ‘drag shield’ can keep the tip from coming into direct contact with the metal.
How long do plasma cutting tips last?
Usually, in normal conditions, we can say that the electrode will wear out first during machine cutting. Typical life time of a set of consumable should last about 1 to 3 hours for about 120 A of mechanized cutting, it’s in function of the job. Cutting at lower current may gets longer consumable life.
What is a good plasma cutter for a beginner?
The Thermal Dynamcis Cutmaster is perfect for the beginner plasma cutter, it is one of the most affordable entry-level plasma cutters and even offers the unique ability of increasing power from 120V to 230V, delivering 27 amps at 120V and 40 amps at 230V.
When should I change my plasma cutter tips?
Within your torch need to be replaced. You can also look at the consumables. Themselves to gauge whether they are nearing the end of their life cycle.
Do you drag the tip on a plasma cutter?
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.
How close do you hold a plasma cutter?
How close do you hold a plasma cutter? You should hold the plasma cutter about 1/4 inch (6 mm) from the workpiece. Holding it any closer can damage the workpiece.
What wears out on a plasma cutter?
The nozzle and the electrode will wear out more quickly than other components, as they are most directly involved with the creation and focussing of the cutting arc. You’ll notice nozzle wear primarily in the quality of the cut you are achieving.
How do you clean a plasma cutter tip?

Will a plasma cutter cut rusty metal?
Plasma can cut any electrically conductive metal including stainless steel, mild steel, aluminum and more, without pre-heating. Plasma is also great at cutting painted, dirty or even rusted metal.
How much does a good plasma cutter cost?
How much is a conventional plasma cutter? Conventional plasma systems will generally range from approximately $15,000 to more than $20,000.

How can I make my plasma cut better?
8 Plasma Cutting Tips to Improve Results
- Plasma cutting basics.
- Tip 1: Choose the right plasma cutter.
- Tip 2: Read the manual.
- Tip 3: Pay attention to setup.
- Tip 4: Trace the path before cutting.
- Tip 5: Use proper technique.
- Tip 6: Check consumables.
- Tip 7: Watch the travel speed.
What does a retaining cap do on a plasma cutter?
The retaining cap essentially holds all of the consumable parts of the torch together. As temperatures at this end of the machine are extremely high, it’s not just the parts creating and focussing the arc that are worn down; the component holding them together also degrades over time.
What are the 4 proper consumable parts for plasma torch?
Consumables have a life-cycle
Keeping track of wear and tear is a key part of maintaining an efficient machine that cuts well and lasts a long time. Plasma cutting torch consumables include: a swirl ring, electrode, nozzle, retaining cap, and shield cap.
How do you cut smooth with a plasma cutter?
How do you cut straight lines with plasma?

What can plasma not cut?
Because the material must be electrically conductive to react to the ionized gas coming from the torch, non-conductive materials cannot be processed with plasma cutting. For instance, plasma cutters cannot cut wood, glass, and plastics, or poorly conductive metals like manganese, lead, tungsten, and tin.
Can you cut bolts off 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.
Do plasma cutters need air compressor?
First, the arc heats the metal until it’s semi-gaseous. Second, the plasma is forced by blasts of air to finish the cut. Therefore, all plasma cutters need an air compressor to generate enough air pressure for the task. If you buy a plasma cutter without a built-in source of air, you’ll need a separate air compressor.
Can you weld with a plasma cutter?
Plasma cutting aluminum can create perfect welds. By using such a cutter, you can keep the surface of the metal outside the welding area moderately cool. Also, it helps prevent the distortion or paint damage that usually comes with flame cutters. Plasma cutters accurately and quickly weld aluminum workpieces together.
How do you cut a straight line with a plasma cutter?
How do you cut fine lines with a plasma cutter?
What does a swirl ring do on a plasma cutter?
The main function of the swirl ring is to control the swirling action of the plasma gas flow around the electrode. It does this to center the arc on the electrode and through the nozzle and constrict the arc for faster cut speeds and thicker cut capability.
What kind of gas do you use with a plasma cutter?
Oxygen has become the standard gas to use when cutting steel as it offers the fastest cutting speed of any plasma gas. Nitrogen is the best choice when it comes to cutting aluminium and stainless steel and it can provide an excellent cut quality.
