Description

A plasma arc welding torch, often referred to as a plasma torch, is a tool used in the process of plasma arc welding. This type of welding torch is designed to create a high-temperature plasma arc that melts and joins metal workpieces. It is commonly used for precision welding applications, especially in industries where high-quality, precise welds are required, such as aerospace and automotive manufacturing.

Since welding torch is the key part of plasma arc welding (PAW), Shijiazhuang Everlight strive for the development of PAW torch. With long-term experience of PAW and highly precise manufacturing capability, we develop a full series of PAW torches, getting widely praised. Our torches have excellent performance under the current from 0.1A to 500A, both manual and auto style, meeting different demands. And 800A torch is customized.

Besides, it is welcome to customizing PAW torches.

FAQ of plasma welding torches

What is a plasma welding torch?

Plasma welding derives its unique operating characteristics from the torch design. Plasma arc welding is a precise process where the slightest variation in front-end part tolerances can lead to poor weld quality, premature failure of the torch body and other problems. As in TIG welding, the arc is formed between the end of a small diameter tungsten electrode and the workpiece. By forcing the arc to pass through the nozzle, the characteristic columnar jet, or plasma, is formed.

What does a plasma welder do?

Foils, wires and screens for welding high-alloyed steel, nickel, copper and titanium alloys of different thicknesses. Ignition is achieved without contact with the workpiece by means of high frequencies and a pilot arc.  

What is the relationship and difference between plasma welding and TIG welding

Plasma refers to ionised gas. For any electric arc welding process, plasma is produced. However, it is named plasma welding because of the intensity of the plasma area. On simple understanding, PAW may easily be mistaken for GTAW as the equipment is very similar. both GTAW and PAW use the same type of power source. However, when looking closely at the welding torch, there are obvious differences. Both the GTAW and the PAW use the same tungsten electrode to start the arc. However, the PAW torch has a copper hole in the ceramic nozzle. Plasma gas is forced through this hole and into the arc, thus creating a compressed arc.

This compression or squeezing makes the arc more concentrated and therefore more intense. One way to see the difference in arc strength between GTAW and PAW is that the PAW may have a water-cooled hose on the nozzle. If you compare GTAW to a clear mist, PAW is a concentrated steam with a strong force.
