• Any mistakes in plasma cutting can impact cut
  quality and affect the consumable's life. Thus,
  avoiding common mistakes can help to control a
  lot of loss and are also easy to take care of.
  Additionally, using quality parts like
  Hypertherm plasma cutter parts will enhance the
  quality of the output and increase the longevity
  of the machine. Now, let us see how you can
  avoid common mistakes and polish the performance
  and output quality of the plasma cutting
  machine.
• Tips to Avoid Common Plasma Cutting Mistakes
• CNC Machine Must Have Correct Pierce and Cut
  Height
• Considering pierce height and cut height will
  save you from many problems like quality damage.
  For instance, if the pierce height is too low,
  the torch will come too close to the plate. And
  this can result in the torch getting splashed by
  molten metal, thus damaging its quality. If the
  pierce height is too high, then the torch will
  remain too far from the plate. And due to this,
  the arc will not be able to transfer, resulting
  in consumable damage or even misfire.

Similarly, cut height is equally crucial. If the
cut height is too low, then the arc will end up
removing too much metal from the bottom of the
plate, which leads to a negative bevel. And if
the cut height is too high, then the tip of the
arc will reach the plate, and it will cause
top-edge rounding and positive bevel. Set the
Gas Flow and Pressure Correctly If the gas
frequency is even a bit high or low, it will
affect the machine adversely. If the gas
pressure is extremely low, then the plasma
cutting arc will never be able to cut the metal
precisely because the pressure would be too
weak. And if the gas pressure is too high, then
you will end up having an unstable arc. Thus,
to make the gas flow correctly, you must check
the gas levels regularly. This way, you can
ensure if the correct amount of the gas is
reaching the plasma torch or not. Ensure That
You Are Following the Operator's Manual
Seriously While using any plasma cutting machine,
you must double-check the operator's manual.
This will help you to ensure the correct amperage
for metal and the thickness you need to use for
cutting. Also, you should follow the
instructions and notes given in the operator's
manual because that will help you to enhance
your output's quality, increase the longevity of
the machine, and promote safety.

• Also, incorrect CNC settings often lead to many
  problems. Like if the cut speed is too slow,
  then the cut pieces will start developing at the
  low-speed dross. This will form a large bubbly
  accumulation of trash along the bottom edge.
  Additionally, slow speeds can also cause a
  widening of the kerf with a lot of top spatter.
  And if the cut speed is too fast, then the arc
  will lag, which will cause a beveled edge with a
  narrow kerf and a small, hard bead of dross
  gathered at the bottom edge of the cut pieces.
• Thus, if you follow the operator's manual and set
  the cut speed accordingly, then it will give you
  a clean edge cutting with minimal dross.
• Other tips to avoid common mistakes that you can
  follow also includes
• Keeping the record of consumable's life.
• Regularly check the torch and consumables to
  ensure there is no rust gathered and if the
  equipment is working fine or not.
• Assembling the torch to align the cut parts
  correctly.
• Use quality parts and spare parts like Hypertherm
  plasma cutter parts and Hypertherm spare parts
  for enhancing the performance of your machine.
• Ensuring the number of consumable parts matching
  in the operator's manual will save you from
  maximum dross.

From now on, whenever you encounter a poor
consumable or plasma cut quality, remember to
check if you are not doing any of the common
mistakes and ensure that you are following the
tips given above. If you do not see any
improvement after applying these tips, then you
should contact the equipment manufacturer to
troubleshoot them with the issues. They will
suggest to you the ideal solution for fixing the
problem. As mentioned above, make sure you have
spare parts for primary machine parts so that
you do not have to waste time till it gets
repaired. Investing in quality spare parts like
Hypertherm spare parts will give you the same
quality as the original. Source
