Plasma cutting is not something one can be an expert at quite easily. Even though the initial concept of plasma cutting may seem simple, there is a large difference between a beginner and a pro. How you handle the plasma cutter, electrode, or materials can affect your outcome. You can still perform plasma cutting without being a pro, obviously, but some certain tricks pros use can make your work smoother.
There is also the issue of malfunctioning in your plasma cutter due that you can prevent. Following some simple tips that we mentioned below, you can complete the project quicker while costing less money. That is why we have prepared four tips and tricks of plasma cutting for novices.
Top Plasma Cutting Tips
Provide the Necessary Air Pressure
While plasma cutting, we use air pressure as a cooling method. Without enough air pressure, the tungsten may get damaged, or worse, the plasma cutter may break. It is definitely an unexpected situation. Before starting the cut, check the instruction in the package of the plasma cutter regarding air pressure. The manufacturers should add the necessary air pressure level to it.
Also, make sure to open the air pressure valve before turning the plasma cutter or cutting. Otherwise, the machine will most likely snap or not be able to do its work.
Keep the Proper Speed
Usage of the right speed is a highly important matter in plasma cutting. Not having a good momentum on your machine may result in the so-called machine cut. Apparently, your plasma cutter should be fast enough compared to the machine amp. If the speed is too lower than the amp, then machine-cut can happen. Also, it can damage the torch. When you are plasma-cutting, high-heated and -pressured gas of 25 thousand to 30 thousand degrees F comes out. The temperature and pressure create the cut on the metal. Make sure that there is the right speed, not so fast; not so slow.
Note that the speed of the plasma cutter is adjustable on the machine. You have to set the correct amp based on the workpiece thickness and machine amp. Refrain from setting the amp equal to the machine amp. Set it a bit lower than the cutter.
Do Not Drag the Torch Nozzle Tip
Dragging your torch nozzle tip on the workpiece will damage the nozzle. It is a common mistake many novices do. It is true that the nozzle must stay connected with the workpiece all the time. But that doesn’t mean you will drag it all the way. Instead, put a little distance between them. Also, before you start the cut, make sure that your hands are in the right places. Keep the hands steady during the cutting. It will provide a smooth cut.
The way how you set up everything is a vital point. A plasma cutter is a small machine. When using it, you can either go side-by-side or through a straight line. But whatever way you choose, you must practice moving the plasma cutter in that way. It will ensure a proper set-up.
You must place everything in the right position and angle. You won’t be seeing the place that you are cutting during the process. Hence, it is mandatory to make sure that the workpiece is not warped. We advise you to perform the plasma cutting on a bench or high enough place. Thus, you can work with proper comfort.
If you want to build your carrier as a plasma cutter, you may need to practice with it. The more you practice, the better you will be ready for an actual program. Set the speed right and choose a top-quality nozzle tip for the works. Moreover, the type of material, arc, and plasma cutting machine also plays a role here.
