Introduction
When it comes to plasma cutting, two main types of systems are commonly used – touch and non-touch. Both have their advantages and disadvantages, and understanding the differences between the two can help you make an informed decision on which one is best suited for your needs.
What is a Touch Plasma Cutter?
A touch plasma cutter, also known as a contact start system, requires the torch to physically touch the metal surface before the arc is initiated. This direct contact between the torch and the metal creates a circuit and triggers the plasma arc. Touch systems are typically more affordable and simpler to operate, making them a popular choice for hobbyists and small-scale applications.
Advantages of Touch Plasma Cutter
1. Cost-effective
Touch plasma cutters are usually more budget-friendly compared to non-touch systems, making them an attractive option for those on a tight budget.
2. Ease of Use
With touch plasma cutters, the user has direct control over the arc initiation, which can be beneficial for precise and controlled cuts.
What is a Non-Touch Plasma Cutter?
A non-touch plasma cutter, also known as a high-frequency (HF) start system, uses high-frequency technology to initiate the arc without having to physically touch the metal surface. This makes non-touch systems ideal for cutting painted, coated, or delicate materials where direct contact may cause damage.
Advantages of Non-Touch Plasma Cutter
1. Versatility
Non-touch plasma cutters are versatile and can cut through a variety of materials, including painted or coated surfaces, without the risk of damaging them.
2. Efficiency
As non-touch systems do not require physical contact, they can provide faster and more efficient cutting, especially when working on multiple pieces or intricate designs.
Conclusion
Choosing between a touch and non-touch plasma cutter largely depends on your specific requirements and the type of materials you will be working with. Touch systems are cost-effective and easier to use, making them suitable for hobbyists and small-scale applications. On the other hand, non-touch systems offer versatility and efficiency, making them ideal for professional or industrial use. Assess your needs and consider the advantages of each system to determine the best option for your plasma cutting needs.
