Tungsten Material Blend Guide
t
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)
