Tungsten Electrode Materials

TRI-MIX Ivory
Sizes:
Description:
.020 x 7"
Tri-Mix contains three oxides scientifically balance the migration and evaporation rates to extend the service life. It increases the number or arc starts before re-sharpening and fewer misfires save money and time. Tri-Mix offers stability and consistency not seen on most other tungsten types. Increasing weld quality and service life dramatically. Lower work function requires less energy to start than 2% Thoriated Tungsten and runs cooler. Tri-MixTM is a non-radioactive tungsten.

Cryo-T Pink
Sizes:
Description:
.020 x 7"
Cryo-T is Thoriated Tungsten that has been cryogenically treated. This process produces a more dense structure of the thoriated and tungsten blend. The results from customers who have tried this Tungsten included:
• Easiest starting Tungsten
• Much longer tip life compared to non-treated 2% Thoriated Tungsten electrodes.
• More consistent welds as a result of crisp starts and longer electrode life.

2% Thoriated Red
Sizes:
Description:
.020 x 7"
2% Thoriated Tungsten contains a nominal 2 wt-% or thorium oxide (ThO2) that is evenly dispersed throughout the entire length of the Tungsten. The most common type of Tungsten used today. Provides excellent resistance from weld pool contamination while at the same time offers the welder easier arc starting capabilities and a more stable arc. Generally used for DC electrode negative or straight polarity applications such as carbon & stainless steels, nickel alloys and titanium.

2% Lanthanated Blue / 1.5% Lanthanated Gold
Sizes:
Description:
.020 x 7"
2% Lanthanated or "rare earth" Tungsten contains a nominal 2wt-% Lanthanum oxide (LaO3). This type of Tungsten is very similar to ceriated as it too is a non-radioactive material. Lanthanated electrodes operate at a slightly different arc voltage than Thoriated or Ceriated electrodes. Were developed around the same time as Ceriated Tungsten to help combat the increasing awareness of the radioactivity of Thoriated Tungsten. Generally used to weld carbon & stainless steels, nickel alloys and titanium.

2% Ceriated Orange
Sizes:
Description:
.020 x 7"
2% Ceriated tungsten contains a nominal 2wt-% of cerium oxide(CeO2). Ceriated is different from Thoriated as it is not a radioactive material. Ceriated Tungsten also tends to last longer than Thoriated and can be used proficiently with AC or DC. In manual applications the Ceriated Tungsten will provide slightly different electrical characteristics than the Thoriated Tungsten but generally no difference will be seen by the operator. Generally used to weld carbon & stainless steel, nickel alloy and titanium.

Zirconiated Brown
Sizes:
Description:
.020 x 7"
Zirconiated Tungsten is excellent for AC welding due to favorable retention of balled end, high resistance to contamination, and good arc starting. Preferred when Tungsten contamination of weld is intolerable.

Pure Tungsten Green
Sizes:
Description:
.020 x 7"
Pure Tungsten contains a minimum of 99.5wt-% Tungsten with no other alloying elements. This allows the tip to form a clean, balled end which provides good arc stability on AC. Pure can be used with DC but does not compare with Thoriated or Ceriated as far as ease of arc starting. More susceptible to weld contamination than Thoriated, Ceriated or Lanthanated. Usually the least expensive of all Tungsten. Pure Tungsten is generally used in the welding of aluminum and magnesium alloys (AC).
