There are a ton of creative pieces you could get from using metal. Some easy and popular things to make include logos for our favorite sports teams, names of loved ones, little cut-outs of animals and cool landscapes. A plasma cutter will allow you to cut these items with precision and quickness as if you were using a sharp razor on paper.
What makes the best plasma cutter for metal art?
The pilot arc
This feature allows the cutter to cut out the metal without making contact. You can position the torch to give you a good view of the metal and the lines before cutting. You will also be able to make trims for a smooth final finish without risk of damaging the design.
A small touch cord
Small plasma cutters are perfect for small pieces of art. They will not strain your body, giving you enough flexibility and strength. Most importantly, the plasma cutter will fit the small diameter of the torch line. You should, however, opt for a machine with a more significant amp value if you are working on a big piece of art.
According to Plasma Cutter Review, there are several factors to consider when choosing a plasma cutter. These include the price, size, cut quality, among other conditions. Once you know which one will give you the best performance, you should understand how to make the most of it.
The preparation procedure
It is paramount that you check the following conditions before starting your task.
- The supply for compressed air should be clean and void of water or oil.
- The air pressure is at the correct levels.
- The nozzle and electrode should have a correct placement.
- The work lead should have a proper connection.
- Consumables should be in good condition to ensure that the air does not get contamination.
The travel speed
The molten metal spray will move the bottom of the plate at a degree between 15 and 20. Slow speeds will cause an accumulation of molten metal at the bottom of the cut, while high rates will not give you enough arc. Both of these setups will result in poorly cut metal art. Read the manual of the plasma cutter to ensure that you get the most of the machine.
The drag cap
The best plasma cutter for metal art will have insulated drag caps covering the nozzle. This feature allows the torch to give you a consistent view of the piece and compliment smooth cuts.
It is better to use the maximum current value of the plasma cutter if you want smooth edges. You should, however, reduce the power when making small kerfs.
Maintain a consistent working distance of between 3/16’’ to about 18’’ from the machine’s nozzle. Avoid moving the torch back and forth because it will derail your cutting efforts.
The desired shape of the piece of art will determine the proper course of the cut. An example is wishing to keep the outer circumference cut out from the circle. You would want to cut a counter-clockwise direction.
