Can You Plasma Cut With A Tig Welder
Plasma cutting is a popular method of cutting through various types of metals, providing clean and precise cuts. On the other hand, TIG welding is a process used to join metals together, creating strong and durable welds. While these two processes may seem different at first glance, they actually share some similarities, which might make you wonder: can you plasma cut with a TIG welder?
The short answer is no, you cannot use a TIG welder for plasma cutting. The main reason for this is that TIG welders do not have the necessary components and features to perform plasma cutting. Plasma cutting requires a high-frequency arc to ionize the gas and create the plasma, which is then used to cut through the metal. TIG welders, on the other hand, operate at much lower frequencies, typically in the range of 60 Hz to 200 Hz.
However, it’s important to note that some welder manufacturers have tried to combine the functionalities of TIG welding and plasma cutting into a single machine. These hybrid machines, also known as TIG/plasma cutters, are designed to provide both TIG welding and plasma cutting capabilities in one unit.
While these TIG/plasma cutters may offer convenience and versatility, it’s important to keep in mind that they may not provide the same level of performance and precision as dedicated plasma cutting machines or TIG welders. Additionally, TIG/plasma cutters tend to be more expensive than standalone TIG welders or plasma cutters.
In conclusion, while you cannot plasma cut with a TIG welder, you can invest in a TIG/plasma cutter if you require both TIG welding and plasma cutting capabilities.
Does a TIG Welder Work for Plasma Cutting?
Plasma cutting is a process that involves the use of a highly concentrated jet of hot plasma to cut through different types of materials, such as metal and ceramics.

Plasma cutters are specifically designed to provide the high-temperature plasma jet needed for cutting through various materials. Attempting to use a TIG welder for plasma cutting could result in subpar performance, slow cutting speeds, and potential damage to the TIG welder.
Conclusion
While TIG welders and plasma cutters both use electric arcs, they are designed for different purposes. TIG welders are primarily used for welding, while plasma cutters are specifically designed for cutting through materials. It is possible to modify a TIG welder for basic plasma cutting tasks, but it would not be as efficient or effective as a dedicated plasma cutter. If you require plasma cutting capabilities, it is recommended to invest in a proper plasma cutter for optimal performance and safety.
