Plasma Cutter Keeps Cutting Out

The arc stability of nc plasma cutting machine directly affects the cutting quality.

Plasma cutter keeps cutting out.

The most common problem the plasma cutter is too small for the metal thickness this is the most common issue we have seen to date. Hello have not logged in to check on the video the problem was solved awhile back in 2015. For those who are still having similar is. Make sure at the least you are running a small disposable in line water separator or upgrade to a desiccant system on your compressor.

When it comes to cnc plasma cutting the same basic questions regarding cut quality always seem to surface. Too much gas pressure will also cause rapid deterioration of electrodes. Plasma arc instability may lead to uneven incision built up edge accumulation etc. When it comes to plasma cutters bigger is generally better only exception to this is if you want a very precise cut for example fine cutting for artwork.

It can cause the arc to be erratic and unstable and may seem like the plasma cutter isn t working correctly. This can sometimes prevent a transfer which will cause the pilot arc to cut out after 4 or 5 seconds. It will also lead to a decrease in the service life of the relevant components of the control system and the frequent replacement of nozzles and electrodes. Clogged cutting tip as the plasma cutter is working there is a tendency to collect dirt particles and metal slag.

Constant gas pressure is important to maintaining the cutting arc. Excess gas pressure is a common cause of hard starting a situation in which the torch fails to initiate an arc when all other conditions for normal operation are correct. With a little troubleshooting you can almost always find a resolution to your cut quality problems by selecting the right plasma torch consumables adjusting your power levels amperage and tweaking cut speeds and cut heights. This slag or metal dust can cause the electrical current to discharge and not make a good connection.
