Frequently Asked Questions
Can I use a plasma cutter on aluminum or stainless steel?
Yes, plasma cutters are excellent for these materials. Because the process uses an ionized gas arc to melt the metal, it works on any conductive material including aluminum, copper, and stainless steel.
What is a pilot arc and why does it matter?
A pilot arc allows the machine to start the cut without touching the metal tip directly to the workpiece. This feature is vital for cutting rusted or painted metal because the arc initiates through surface contaminants. It also significantly extends the life of your torch consumables.
How much air pressure do I really need?
Most machines operate best between 60 and 80 PSI. You should check your specific owner manual, as having too little pressure results in a poor cut, while too much pressure can blow out the arc prematurely.
Will a plasma cutter work on a standard 15 amp house circuit?
Smaller units designed for 120V power will function on a 15 amp breaker, but they may trip it if you push them to their maximum settings. For consistent performance, a dedicated 20 amp circuit is much better.
Do I need a special gas for my plasma cutter?
For most shop work, clean and dry compressed air is all you need. You must ensure your air supply has a moisture filter or dryer installed, as water in the lines will destroy your torch consumables and ruin your cut quality.
