What is E3 tungsten good for?
E3 Electrode Features and Benefits: Excellent ignition and consistent welding properties. Universal and suitable for all applications for DC and AC welding pf non-alloyed and high-alloyed steel, aluminum, titanium, nickel, copper, and magnesium alloys. Reliable and usable for automated welding.
What is in E3 tungsten?
MATHESON Select® E3 Tungsten Electrodes use 1.5% lanthanum oxide (plus other oxides) instead of 2.0% thorium oxide.
What color band is E3 tungsten?
Purple
They are universal and suitable for all applications in the whole range of AC and DC welding of non-alloyed and high-alloyed steel, aluminium, titanium, nickel, copper and magnesium alloys….Lower degradation to the electrode tip.

Which tungsten is best?
CHOOSING A RARE EARTH TUNGSTEN Ceriated and lanthanated tungstens hold up better for AC TIG applications than 2% thoriated tungsten. While thoriated tungsten remains the most common in DC TIG, because of concerns about radiation, most experts strongly recommend ceriated or lanthanated electrodes for AC and DC TIG.
Is tungsten an essential variable?
To produce the high quality orbital fusion welds required of today’s high tech industries, tungsten electrode shape is an important variable that must be kept consistent. Most orbital manufacturers require a precise tungsten length.
What color tungsten is best for stainless?
What color Tungsten should be used for stainless steel? The thoriated red electrode is ideal for stainless steel welds. It provides the optimal heat generation, bead formation, and weld penetration to give smoother welds.
What is essential variables in welding?
Essential variables are those to which a change, as described in the specific variables, is considered to affect the mechanical properties of the weldments; hence any change in any essential variable will require requalification of the welding procedure.
Which is better E3 or 2% tungsten?
Pkg of 10 – 7 inch .040 diameter E3 tungsten electrode. Superior to 2% Thoriated tungsten in electrode life and arc stability. E3 is made from a combination of 3 oxides and is not radioactive, like thoriated tungsten.
Which is better an E3 electrode or a 2% electrode?
Pkg of 10 – 7 inch E3 tungsten electrode. Superior to 2% Thoriated tungsten in electrode life and arc stability. E3 is made from a combination of 3 oxides and is not radioactive, like thoriated tungsten. E3 runs cooler than other types of tungsten electrode and provides fast, consistent arc starts.
Which is the best tungsten electrode for welding?
E3 runs cooler than other types of tungsten electrode and provides fast, consistent arc starts. It is capable of performing in both AC and DC welding applications. E3 is the only tungsten electrode you’re going to need – can be used for both AC and DC welding applications Non-radioactive oxides – 1.5% Lanthanum, .08% Zirconium, .08% Yttrium
What is this new E3 found it at?
What is this new E3 found it at: ( https://www.weldingcity.com/tig-tung…-tungsten.html ), I’ve been playing with tungsten to have fun, it’s like being creative artwork on spot. Anyways, does it do the same job as the 2%Thoriated or is it the same as the pure tungsten outcome?
