Plasma Cutter Keeps Cutting Out

This slag or metal dust can cause the electrical current to discharge and not make a good connection.

Plasma cutter keeps cutting out.

It can cause the arc to be erratic and unstable and may seem like the plasma cutter isn t working correctly. Make sure at the least you are running a small disposable in line water separator or upgrade to a desiccant system on your compressor. 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. Hello have not logged in to check on the video the problem was solved awhile back in 2015.

Constant gas pressure is important to maintaining the cutting arc. 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. When this happens you should stop cutting and wipe off the end of the tip to clean it of any dust or slag. For those who are still having similar is.

The internal plasma cutter s separator should be checked or drained periodically. This can sometimes prevent a transfer which will cause the pilot arc to cut out after 4 or 5 seconds. Too much gas pressure will also cause rapid deterioration of electrodes. 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.

The arc stability of nc plasma cutting machine directly affects the cutting quality. Clogged cutting tip as the plasma cutter is working there is a tendency to collect dirt particles and metal slag. 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. Plasma arc instability may lead to uneven incision built up edge accumulation etc.
