Increase Cutting Speed, Optimize Settings, And Replace Equipment Regularly
Speed It Up
Increase cutting speed to minimize dross formation and achieve cleaner cuts. Find the sweet spot for your CNC plasma machine’s capabilities.
Fine-Tune Your Settings
Adjust your machine’s parameters, like gas flow, amperage, and torch height, to optimize the cutting process and reduce dross. Precision is key!
Mind The Material
Different materials require specific techniques. Experiment with varying cutting speeds, consumables, and techniques to conquer the dross challenge for each material.
Stay Sharp, Stay Clean
Regularly inspect and replace worn consumables like nozzles, electrodes, and shields. A sharp torch and clean components ensure cleaner cuts and less dross.
Embrace Post-Cutting Rituals
Employ post-cutting methods like grinding, sanding, or deburring tools to remove any remaining dross and achieve the pristine finish you desire.

Five Steps To Reduce Dross
1. Use Flux
Flux is a material that helps remove [the] dross from metal. It causes impurities to rise to the surface and can be easily wiped or scraped away using a wire brush.
2. Change Your Welding Technique
As you weld, move the arc between two separate points so that you don’t create a pool of molten metal. This will help reduce the amount of dross created.
3. Keep Your Metal Clean
Before welding, make sure that all dirt, rust, and other contamination is removed from the surface of the metal to lessen the chance of dross being produced.
4. Use Higher-Quality Filler Metals
Filler metals with higher melting points will help avoid dross formation.
5. Increase Welding Speed
The faster you weld, the less time impurities have to accumulate in the molten metal and form dross.

You Must Understand The Cause Of Dross Formation
Excess dross can be a common issue in various industries, including metalworking, welding, and casting. To avoid and get rid of excess dross, [you must] understand the root cause of the problem. One of the most effective ways to prevent dross formation is to maintain proper temperature control during the manufacturing process.
Additionally, using high-quality materials and equipment can also help reduce the amount of dross produced. In some cases, implementing a post-processing step, such as grinding or sandblasting, can help remove excess dross. It is important to note that the specific approach to avoiding and getting rid of excess dross may vary depending on the industry and application.

Use The Right Tool And Clean The Area First
Make sure you’re using the right tools: If you don’t have the right tools or techniques, you won’t be able to get rid of all the dross. Invest in good quality brazing rods, flux, and torch tips that are designed for your specific application.
Clean the area before you start: Make sure any dirt, debris, or other contaminants are removed from the joint area before you begin brazing. This will help ensure that you get rid of as much dross as possible.
Use the right flux: It is important to use the right flux when brazing. Non-activated fluxes are best for precision brazing, while active fluxes can work better on thicker pieces and in applications where a large amount of heat is needed.
Brazing in a vacuum: If you’re brazing in a vacuum, you’ll be able to get rid of more dross because the oxygen has been removed from the environment, and no oxidation can occur. This is ideal for precision applications that require high levels of accuracy and clean joints.
