10. TUNGSTEN OPTIONS

Diamond Ground Products stocks the following tungsten electrode types in 7" lengths with diameters ranging

from .040" to ¼". Custom diameters and lengths also available by special order.

TRI-MIX- WS2

Non-Radioactive – Color Code: Cream

Tri-Mix™ tungsten is non-radioactive tungsten with the similar performance to 2% Thoriated tungsten. Three

Oxides scientifically balanced promote migration and evaporation rates that result in extended tungsten life.

This tungsten offers stability and consistency not seen on most other tungsten. Results commonly received in

some applications include an increase in the quality of welds, a dramatic increase in service life as well as, an

increase in arc starts before resharpening and fewer misfires saving the customer money and time.

CRYO-T

Radioactive – Color Code: Pink

Cryogenically treated thoriated tungsten which provides a more dense structure of the thoriated blend. Easier

starting as compared to 2% Thoriated. Performance includes easier arc starts as well as extended tungsten life.

2% THORIATED & 4% THORIATED

Radioactive element – Color Code: Red / Orange

2% Thoriated material is the primary tungsten used in the United States. Used primarily for DC Welding, it

has a low work function and provides high load and amperage capability. Vapors, grinding dust and disposal of

thorium dioxide raise health, safety and environmental concerns.

1.5% LANTHANATED & 2% LANTHANATED

Non-Radioactive – Color Code: Gold / Blue

The most commonly used, non-radioactive tungsten used as an alternative to 2% Thoriated tungsten. 2%

Lanthanated offers a long electrode life under heavy or pulsing amperage loads. Common results include,

improved and stable arc starts at any amperage level, good resistance to contamination and long service life.

Because of its high ability to resist thermal shock, the user receives excellent ignition with a lower burn-off rate.

2% CERIATED

Non-Radioactive – Color Code: Grey / Formerly Orange

Recommended for short welding cycles on low-amp, DC orbital tube, pipe, thin sheet, and small part

applications. Provides low current capacity and arc ignition with good arc stability. Ceriated tungsten is not

recommended for higher applications, because the oxides contained in ceriated material tend to migrate very

quickly to the heat at the tip of the electrode.

ZIRCONIATED

Non-Radioactive – Color Code: Brown / White

Recommended for use in radiographic-quality welding, where tungsten contamination must be minimized.

Zirconiated material tends to ball-up easily in AC applications. Performance includes good arc starting and

current capacity. Not recommended for DC Welding.

PURE TUNGSTEN

Non-Radioactive – Color Code: Green

Non-Radioactive with a low current capacity. Recommended for use in AC welding of aluminum.
