It can be done by disconnecting the torch knob from the mounting tube. You can use cotton wool together with the electric contact cleaner. Any dust present should be blown out. Note any damage or leaks that could cause dysfunctionality. It can be daily, before and after cutting.

2. Power supply

Check for any dust along the PC boards. Metal dust and air pile in the PC, which could prevent the normal operations.

3. Clean the machine components

The gears, racks, and rails at times may fail to run well. You can use a degreasing agent and lubricate the gears with dry lubricants like graphite. However, while lubricating, be moderate and cautious to avoid spilling on the rail area since lubricants increase vulnerability to wearing out.

4. Electrodes

The electrodes are made of a tip known as hafnium, which enhances conductivity. This metal, however, with time wears out. To be sure of the electrodes starting to wear out, you can take a look at the tip of the electrodes. If you suspect wearing out, then you need to replace them. This procedure can be done weekly or fortnightly.

5. Ground clamp

Though it does not wear out easily, it is essential to keep checking on it, probably after three or four months. Ensure that the springs are still holding in perfect position, which is replaceable if loose or weak.

Though some plasma cutters are expensive because of additional features, reliability, and ease of use, manufacturers provide affordable plasma cutters. With this option, a welder can consider Lotos LTP5000d plasma cutter, which is a preference by many welders

What should I look for in a plasma cutter?

Before purchasing a plasma cutter, a user gets stranded on identifying the best. Nonetheless, before making a decision concerning a good plasma cutter, there are notable features to look for in this machine. The features, among others, include air supply, input power, ease of use, the duty cycle, portability, and a built-in inverter.

Do you need gas for a plasma cutter?

In most cases, the plasma cutters have in-built air, which could be nitrogen, oxygen, or argon. At times a welder can use shop air, which enables the smooth running of plasma cutters as well.

Do you need a welding mask for plasma cutting?

Since welding produces sparks, shielding yourself from hurt and damage is essential. To be safe, do not expose your skin. You could wear goggles or plasma cutting glasses to protect your eyes. A helmet could cover your head from impending harm. Besides, you can wear a welding jacket and welding gloves, which serve well when using a plasma cutter.

Will a plasma cutter cut rusty metal?

Ideally, plasma cutters are meant to cut through steel. Therefore, any thick, rusty, and dirty still is not an exception. The same way it can efficiently cut stainless steel, so can it cut any rusty metal.

What material can a plasma cutter cut?

The design of a plasma cutter is in a way that it can cut through materials that conduct material. It, therefore, implies that metals like aluminum, brass, alloy, and stainless steel can be finely cut using this device.

Can a plasma cutter cut glass?

In comparison to cutting metals, glass is considered more dangerous. The experience with such an experiment is not a good one since it can cause more harm and threaten a person’s safety. Trying this procedure is a risk and a threat to a person’s safety.

Are plasma cutters dangerous?
