TIG Tungsten Electrodes

Commercial welders know that selecting the proper tungsten is important for making successful TIG weld. The welder has to make sure that one is using the right tungsten for the type of metal that is being welded; the type of technology used in for example transformer or inverter, and the thickness of the metal you will need to weld. This leaves the welder with a variety of sizes ranging and types of tungsten, for example Pure Tungsten (TP), 2% Thoriated Tungsten (TT2), 2% Ceriated Tungsten (TC2), and 2% Lanthanated Tungsten (TL2). LONGEVITY offers tungsten electrodes of excellent quality and gives information which tungsten is required for the application.

The Pure Tungsten (TP) – (green tipped) - forms a ball on the end and is designed for use with transformer-based power sources for AC welding of aluminum. However, LONGEVITY does not carry transformer based technology due to the size and the weight of the TRANSFORMER welders. That is why this tungsten is rarely sold by our sales staff

2% Lanthanated is reccomended for aluminum and stainless steel applications making it a popular choice.

Types of GTAW Tungsten Electrodes

The 2% Thoriated Tungsten (TT2) – (red tipped) - is the most common tungsten that is used now with LONGEVITY DC TIG. It is used for DC welding of mild steel, bronze, and stainless steel and basically all other metals except aluminum and offers excellent performance. The welders should know that this tungsten has a low level radiation hazard and is not recommended for welding aluminum. LONGEVITY recommends this tungsten with our stand alone DC only TIG Welders - our WeldMax series multi-purpose welders. The 2% Thoriated Tungsten should be used when working with Inverter Welders.

 

The 2% Ceriated Tungsten (TC2) – (grey tipped) – is a great substitute for the 2% thoriated tungsten and is designed for transformer and inverter of based power sources. When transforming DC welding, this tungsten requires less amperage to start and could be applied on thinner metals. It offers a stable arc and could be used for AC and DC welding with inverter power sources. No surprise it is our most popular and sold tungsten as it can be used to weld all kinds of metal in both AC / DC modes with the LONGEVITY INVETER TIG welders. The unit goes well with LONGEVITY’s ArcMate 200AMP ACDC TIG/STICK unit or with the WeldAll series for multi-functional welders and plasma cutters because of the versatility of the AC DC welding.

 

The 2% Lanthanated Tungsten (TL2) – blue tip – is the most popular substitute for the 2% thoriated tungsten. It has a longer life span than the 2% thoriated tungstens and provides a nice alternative. This type of tungsten could be used with both transformer and inverter technology on both AC and DC modes.
