How to choose a plasma cutter under $300?

How to choose a plasma cutter under $300

Choosing a plasma cutter can be a hectic task, especially if you are tight on budget. Whether you are a hobbyist or a professional operator/welder, a good plasma cutter can benefit during your artwork, sculpturing, or whatever you are going to use the plasma cutter for.

We have written a complete guide about all the factors that decide which plasma cutter is best for you.

Ease of Use:

Choosing a difficult plasma cutter may make your life difficult. As many people buy a plasma cutter for under $300 for their DIY jobs or small tasks, an easy cutter will save you time and money. You can start right away when you get it easy to work with a plasma cutter. Moreover, a user manual may help you to start with your plasma cutter.

Lightweight:

If you buy a heavy-duty big plasma cutter, it may be a great choice but cannot be portable for you. Lightweight plasma cutters are easy to move with, and you can carry them without any hassle. Whether you work in your DIY workshop, or home, site, or industry, a portable and lightweight plasma cutter can move anywhere with you.

Size and type of material:

During your welding or sculpting jobs, you come across many different materials. A plasma cutter has different cutting thickness capabilities for different materials. For example, if it is cutting a hard metal, it may have less thickness capability than soft metal. So before buying a plasma cutter, you must know which cutting capacity your plasma cutter is capable of.

Parts included in the box. 

A plasma cutter has many important parts. Some plasma cutters come with all of their parts within the package. These parts may include a torch, cables, air filters and regulators, and other important parts. Look into the parts included in the box before you buy a plasma cutter. If you don’t want to have more investment, buy a plasma cutter with all the essential parts.

Warranty

Warranty is as important as the plasma cutter itself. Many companies don’t offer any kind of customer care services or warranty. So don’t think of buying such plasma cutters. You should choose a plasma cutter that has a warranty from either its seller or manufacturer. It can save your time and money in case you need any repair or replacement.

How to maintain a plasma cutter?

Like every other craftsman, welders should also upgrade and regulate themselves. The same goes for their machines. If you don’t upgrade and maintain your machine, you might end up having a low-quality function. So how do we maintain our plasma cutting machines? We have written all the basic and important steps in the following section.

1. Cleaning of the torch body

You can easily clean the plasma cutter torch by disconnecting the torch from the knob. Take an electric contact cleaner and use cotton wool to clean the torch. Make sure that the torch does not have any damage or leaks on it. The cleaning process can be done before and after using the plasma cutter.

2. Cleaning the power supply 

If the PC board has any dust, make sure you remove it from there. Any dust or metallic particles may harm the plasma cutter and can stop the functionality too.

3. Cleaning the machine components

You should clean the gears, racks, and rails very often. Any dust or debris stops the functionality and may lead to some serious issues in the working of plasma cutters. Use dry lubricants like graphite to lubricate the gears. Avoid the spilling of lubricants as they may impair the life of the rail area.

4. Electrode

Maintaining a proper electrode is crucial. The electrodes start wearing out after some time. So keep a regular check on the tip of the torch. If they start wearing out, simply replace them.

5. Ground clamps

Make sure you inspect the ground clamps every month. If they get weak, try to replace them. You may need their replacement after three to four months.
