Plasma cutting is a term that is used to cut through electrically conductive materials by accelerated shot of hot plasma. Plasma is one of the fundamental states of matter, others being solid, liquid and gas. It however does not exist naturally on Earth and has to be generated artificially. Steel, brass, aluminum bars, stainless steel are typically cut by plasma torch. Due to high speed precision system and low cost operation, plasma cutting has now become more popular in numerous industrial sectors. Large scale industries, fabrication units and industrial manufacturing companies mostly use this plasma cutting technology for designing their products.
Uses of Gas and Plasma Cutting Torch:
Owing to its cheap cost, with speed and precision, it used by large scale industrial sectors to even small ones. Plasma cutting is also used in fabrication shops, automotive shops, scrapping outlets and industrial construction sites. It is one of the most effective ways to cut thick and thin elements equally. Different gases are used depending on the thickness of the material to be cut to obtain the best precision cuts, productivity and to ensure the overall life of the material.
Different Kind of Uses of Gas and Plasma Cutting Torch:
There are also multi gas torches that offer flexibility for shops involved in cutting various materials. Take a look at the number of gases used to cut mild steel, aluminum and stainless steel.
#1. Oxygen:
Oxygen is the standard gas used to cut mild steel. It provides the bets cut coupled with fast cutting speed of any plasma gas. However it is not advisable to cut aluminum and stainless steel with oxygen.
#2. Air:
Air is the most versatile plasma gas. It also produces good cut quality along with speed on mild steel, stainless, and aluminium equally. Since you do not have to purchase gas, the cost of operation involved here is less. Shop air must be cleaned to remove to make them free of contaminate, oil and moisture.#3. Nitrogen:
Early plasma torches made use of nitrogen. It is the best choice to cut aluminum and stainless steel. It ensures good quality and longer life for the material in hand.
Argon Hydrogen: The Cutting and Fabrication Process Of Steel And Aluminum
Argon hydrogen is the best choice for cutting stainless steel and aluminum. Since it is the hottest plasma gas, it ensures maximum cut quality. In multi gas torches, it provides a very smooth and polished surface on stainless steel. Nitrogen here is used a shield gas with argon hydrogen. The only disadvantage of this combination is the cost involved.
How Would You Operate the Gas And Plasma Cutting Machines?
Think through when you find the right plasma cutting for material in hand. Quality and life is an important thing to keep in mind when deciding. Besides, experts know this issue better. Entrust this job to an expert to get things done perfectly. They make the best choice since they are experts in this field.
An eye protection and face shields is a must thing to have when performing plasma cutting tasks. It will protect you from debris and arc eye. Typically, a dark shade as lens works best. Otherwise a green lens is recommended. Also, leather gloves and aprons are another way to keep yourself protected and safe. They prevent burns and sparks.
Plasma torches were once very expensive. Hence they were used only in professional welding shops and garages. Modern plasma torches today that are available are cheaper and within the price range of anyone. Whereas the older ones were heavy, the newer ones are light weight and can be easily ported from one place to another.
