the correct tungsten electrode is important to getting high-quality
welds and making your welding easier. Some important factors to
be considered in making the right choice are type of power source
(Inverter or transformer), material to be welded (steel, aluminum
or stainless steel) and the thickness of the material.
HTP offers the following premium quality tungsten ground to
a high quality finish. All tungsten is 7” long and can
be purchased individually.
Pure Tungsten (TP) – green tip - Pure tungsten readily
forms a ball on the end. It is generally used with transformer-based
power sources for AC welding of aluminum.
2% Thoriated Tungsten (TT2) – red tip - This tungsten
is the most common tungsten currently being used. It is generally
utilized for DC welding of steel and stainless steel and offers
good overall performance. A drawback is that this tungsten has
a low level radiation hazard.
2% Ceriated Tungsten (TC2) – grey tip – 2% ceriated
is an excellent substitute for 2% thoriated tungsten if you are
using a transformer-based power source for DC welding. This tungsten
is popular for thinner materials because it requires less amperage
to start. It offers a stable arc and can be used for both AC
and DC welding with inverter power sources.
2% Lanthanated Tungsten (TL2) – blue tip – 2% lanthanated
is probably the most popular substitute for 2% thoriated tungsten.
It offers good arc starting characteristics and longer life than
2% thoriated. It can be used for both AC and DC welding with
both inverter and transformer power sources.
