Gas Plasma Cutting Machine

Monday, February 28th, 2011

When it comes to manufacturing and producing goods, the processes invariably involves cutting and joining of metals such as steel, aluminium, stainless steel, titanium, copper, nickel and other alloys. Plasma Cutting Machines are quite reputed and well established, they happen to be the most reliable machines when it comes to cutting of metals. These metals mentioned above have a lot of applications and machines or goods created based upon them are quite good and best thanks to the sturdy nature of the metals being used. In order to manufacture such goods or machinery, the metals need to be cut into several shapes and sizes and has to be highly precise as per the requirements. That’s where plasma cutting machines come into the picture. They are the best tools for accomplishing the task.

Plasma Cutting machines also come in Air or Gas models. They are preferred for cutting electrically conducting materials. They are the best for cutting rusted metals. They have a wide range of mechanizing. They are highly accurate in execution. Gas Plasma Cutting machines are very easy to handle and use friendly in many ways. They are very easy to operate as well. Thus eventually anyone can learn the art of welding quite easily, of course with proper protection. If not, the person can be severely injured. The Gas Plasma Cutters are constructed in the most optimizing possible ways. It has very basic features and operating techniques and thus eventually anyone can go through the manual and get accustom to its usage.

Plasma Cutter Is A Tool To Cut Metals

Monday, May 24th, 2010

Transportable, light plasma cutters make use of 110 volts, through an amount produced of approximately 15-40 amps. In order to make things easier and to make simple usages, these plasma cutters repeatedly featured with involved air compressors.

The exterior of the metal on the outside of the cutting area remains calm and that is one of the major benefits of utilizing a plasma cutter. This put off the twisting and paint harm that can take place by means of other fire cutters. A thin HAZ (heat affected zone) also permits to utilize the models for exact curved stripe cutting.

Larger cutters will come with a productivity of approximately between 50 and 80 amps and they are 220 volt systems. An industrial plasma cutters will be able to cut metal up to 2 inches thick (5cm), whereas a hand-held model can be utilized to cut conductive metal which is ½ or (1.25cm) inch thick.

Clearing the myths about plasma cutters

Thursday, May 6th, 2010

There has been a common misconception that the plasma cutters are expensive and difficult to use. But with the advent of advance technology, the plasma cutters have become highly versatile and they can be efficiently used on thick and thin metals. One of the most important highlight of plasma cutters is that they are portable, easy to use and economically efficient.

Some myths have been linked with the plasma cutters since long. One of the most popular false beliefs is that the plasma cutters are expensive than all other cutting tools. It is true that they are higher priced, but there is a difference between price and cost. The plasma cutting machines would have significant cutting speed and delivers quality cuts in the end. Operators would finish the metal cutting fast and there would be less dross with better edge quality.

Another prominent belief is that the plasma cutting machines are only used for cutting thin metals. It is in fact efficient for cutting as much thin metals but they can be used on thick metals too. Since the plasma cutters deal with advanced technology, people have an impression that it is tough to handle. This is completely wrong since the portable plasma cutters are easy to use even for first timers.

Tips To Maintain Plasma Cutter Torches

Monday, April 26th, 2010

When you need a perfect cut, it can be easily attained with the help of a plasma cutter, but when you are a newbie, then you will have to follow some tips until you get used to the whole process properly. If you like to get the best cut and not waste a good piece of metal then follow a set of plasma cutting tips to save your metal as well as the plasma cutter machine.

A common tip for people applying O-ring lubricant is to use only needed amount so that you can see enough shine on the O-ring. It is important that you will have to remove the shields before adding anti-spatter compounds on it.

All you have to remember is that a lot of both materials will dirty the torch, which will result it early torch failures. Same way, grease or other any other such lubricants must not be applied to torches, this will again give problems to torch, as torch don’t need any lubrication. On the other hand, lubricants are good conductors of electricity and this can again damage the torch.

Knowing About Plasma Arc Welding

Monday, March 29th, 2010

Welding is an old process but then inventions and improvements in this field are still up and happening. These days we have a lot of special equipments and different methods to carry out welding and metal cutting works depending up on our needs.

Now here we are gonna study about latest welding process that is more or less like a typical arc welding process and it is nothing but Plasma Arc Welding. The important difference between arc welding and plasma arc welding is that the electrode is directly inserted inside a small nozzle in plasma welding.

Plasma arc welding machines can be operated manually or even automatically as desired. This plasma arc welding process is something that produces thin and a very much straight line of welding. The biggest advantage of this process is that the nozzle keeps the flow without deviation and hence more accurate and powerful weld is obtained.

As the electrode is inserted inside a small nozzle, the inert shielding gas is separated and the arc becomes intensified. Plasma welding machines and processes can be manually or automatically operated. They tend to produce very straight and thin welds. The nozzle allows much less wandering of the arc compared to normal TIG and MIG welding making thin precision welds possible.

How To Make The Best Use Of Your Plasma Cutter

Wednesday, October 7th, 2009

Plasma cutting machines are of different types. Once the best choice has been made, the followings points should be remembered to make the best use of your cutter.

  • Set up the cutter as mentioned in the instruction booklet.
  • Wear the safety gears as mentioned in the manual. Safety gears protect your eyes, hands and face.
  • Do not try to pierce the work piece at a 90 degree angle. Instead a 60 degree horizontal and 30 degree vertical approach to the metal is advisable.
  • Avoid touching the nozzle to the metal piece when applying current levels that are 45 amps or more. This will improve the life of the nozzle.
  • Move the cutter at the right speed to create that high quality cut.
  • Maintain a distance of 3/16″ to 1/8″ from work to the nozzle.
  • Try to use the pilot arc mode for a short span of time.
  • Use the cutter with high power electricity as it works at its best then.

Understanding Plasma Cutting Systems

Monday, June 1st, 2009

Plasma cutting systems are wonderful tools for creating structures that we use everyday. They are used to help build the skyscrapers we live and work in. It may be the plasma cutting systems that you look for if you are building a car or anything made out of metals.

Plasma itself, harnesses a power that is released once you have exposed it to intense temperatures. The heat will break apart the atoms electrons. The electrons are separated from their nucleus creating a huge amount of energy. This energy is the heart of the plasma cutting systems.

This would be considered the knife, in that the energy release in a controlled environment will slice steel, like butter. The harnessing of this enormous power, gives the plasma cutting systems their uniqueness.
