Tungsten Material Blend Guide

ArcTime™

Hybrid All Purpose Tungsten Electrodes

This non-radioactive performance proven formula combines rare earth

materials with tungsten to produce the best all-purpose tungsten

electrode on the market . Experience reliable arc starting even after

numerous ignitions .

Color Code: Sky Blue™ (US) . Not std in Europe or Japan .

2% CERIATED

Suitable for low-amp, DC orbital tube, pipe, thin sheet, and small part applications . This formula

offers low current capacity, low arc ignition, good arc stability and is non-radioactive .

Color Code: Gray

(US, Europe and Japan)

2% ICE-T™

Radioactive tungsten formula for easy arc starting, good arc stability and current capacity, and

resistance to weld pool contamination . Vapors, grinding dust and disposal of thorium dioxide

raise health, safety and environmental concerns . Use only when contractually required by FAR

specification .

Color Code: Pink

1.5% LANTHANATED

Another good general purpose non-radioactive replacement for 2% Thoriated, and similar in

performance to 2% lathanated . It features excellent ignition and re-ignition properties and

good service life .

Color Code: Gold (US) .

Not std . in Europe or Japan .

2% LANTHANATED

This formula is a good general purpose non-radioactive replacement for 2% Thoriated . It has

excellent ignition performance, low-burn-off rate, excellent re-ignition, and good service life .

Color Code: Blue (US) .

Not std . in Europe . Yellow-Green (Japan) .

2% THORIATED

This formula is a popular general purpose electrode due to the excellent arc behavior and good

tip life . This is a radioactive formula, however . Vapors, grinding dust and disposal of thorium

dioxide raise health, safety and environmental concerns . Use only when contractually required

by FAR specification .

Color Code: Red

(US, Europe and Japan) .

1% ZIRCONIATED

Used for radiographic-quality welding where tungsten contamination must be minimized .

Balls-up easily in AC applications, good arc starting and current capacity . Non-Radioactive .

Color Code: Brown (US) White (Europe) .

Not std . in Japan .

PURE TUNGSTEN

Pure tungsten has a high work-function which makes it difficult to start and maintain a stable

arc . High burn-off rate results in short service life .

Color Code: Green

(US, Europe and Japan)
