Dynaweld Plasma Cutting
Plasma Cutting
In this video, Andrew Bosco from Dynaweld, the Welding Supplies Specialists, shows us how to cut through any job with plasma cutting.
Metal. Sometimes you need it welded together.
At other times you want to cut it apart.
Fast, clean and with a minimum of fuss.
May we introduce you to Plasma Cutting
Plasma Cutting is a high speed/low cost cutting method.
It is a process that cuts through electromagnetic materials with an accelerated jet of hot plasma.
What is plasma?
Plasma is the fourth fundamental state of matter.
Solids, liquids and gas being the first three, and in this order.
Matter changes from one state to the other with the introduction of heat.
Plasma is the final result.
How does plasma cutting work?
The plasma arc results from heating compressed air electrically and at a very high temperature. This in turn, ionises its atoms and enables them to conduct electricity.
The air from the welding torch is forced through the swirl ring, it is then ionised by the electrical arc from the electrode, and it turns into plasma, which flows from the torch to the workpiece.
As electricity from the cutting torch travels down the plasma, it creates sufficient heat to melt through the metal. The high velocity plasma and compressed gas blow the hot melted metal away to cut straight through.
Plasma looks and behaves like a high temperature gas – but there is an important difference – it conducts electricity and can cut through any electrically conductive metal.
The plasma torch has a safety trigger that needs to be released before you are able to start the arc. When the trigger is squeezed, the power supply produces a DC current that flows through this connection and also initiates the plasma gas flow. The DC current flow then switches from electrode to nozzle, to a path between the electrode and the work piece. This current and airflow continues until the trigger is released.
As electricity from the cutting torch travels down the plasma it delivers sufficient heat to melt through the workpiece.
What can you do with all that awesome heat?
The plasma jet can reach temperatures of up to 22,000 degrees celsius.
Plasma cutters are used for cutting and gouging.
With the average 240 volt handheld system, all that great heat and power is capable of cutting metals that are up to 10 – 15 millimeters thick. The bigger the machine – 415 volts can cut through 30 mill – the bigger the cut.
Always work clean for better results
Plasma relies on a source of compressed air and a substantial amount of electrical power. The air has to be as clean as possible. Air filters do their job to remove moisture, oils and particles. Keeping everything clean ensures that you will enjoy a faster and smooth plasma cutting experience.
At Dynaweld, we can help you to understand airflow rates and pressures. We can also help you choose the right amount of voltage needed for your work.
The Joy of Plasma Cutting
Plasma is fast becoming a more affordable and portable option. No gas bottles = less cost and less transportation concerns.
A key advantage of Plasma Cutting is its ability to cut nonferrous metals.
These include aluminium, stainless steel and cast iron.
Metals that are becoming increasingly popular on many jobs and work sites.
Speed? Tick.
Precision? Tick.
Minimal slag, smooth cuts, relatively simple to use, time and penny saving. Tick, tick, tick.
Nice to meet you Plasma Cutting.
