Consumables for a plasma cutter can be a large part of the ongoing expenses you’re having with your machine, if you choose a cheap machine like the LTP5000D. Where you will see your money going is towards cutting tips and electrodes.
It is very likely that you may end up damaging the tip if you’re just starting out and don’t have the technique right yet. Secondly, an electrode that is way past its prime can have an effect on how much work you’re managing to get done as it will significantly slow down your cutting. When you’re wanting to not just make beautiful cuts, but also do so in a timely manner, you will end up having to make sure your consumables are also doing what they’re supposed to.
There are also other consumables to keep in mind if you don’t have a portable plasma cutter but rather a CNC. Some of these, it can even be hard to notice that they have deteriorated over time and they include the nozzle, the swirl ring, the retaining cap and the shield. Make sure that you keep an eye out for these parts so as to get better cuts in the future!
