Innovative thinking. A quality and
service-first attitude. Fresh
approaches to design, manufacturing,
and packaging. Worldwide strength.
That’s Lincoln Electric.

Lincoln’s Innershield® Wire
Innershield wire by Lincoln Electric is one of the most user-friendly,
convenient, versatile wires on earth. This exceptionally feedable
and consistent wire includes shielding, slagging and deoxidizing
materials built right in to its inner core. That means no external gas
bottles or flux on the job! It’s a superb choice for bridges, offshore
drilling rigs, and other outside welding applications where winds are
a factor.
• Shielding, slagging and deoxidizing materials are built right in to
the inner core.
• No need for external gas or flux.
• Many Innershield wires to choose from – a perfect wire for every
application.
• One of the most user-friendly welding processes on the market
today.
• A great choice for use in moderately windy conditions.
• As with all of our wires, Innershield’s arc characteristics are outstanding! That’s because we pay more attention to chemistry,
quality of raw materials, and manufacturing processes than any
wire manufacturer in the world!
• Best of all, Innershield is designed and built by Lincoln Electric.
Our company is all about innovative thinking – about listening
and responding to the needs of welding professionals – about
finding ways to make welding quicker, stronger, and more
efficient.

Advantage Lincoln
More precise control. Innershield’s open arc process allows the
operator to control the placement of the weld metal and the puddle with exceptional accuracy.
More consistent weld deposits. Innershield performs better
because Innershield is built better. The best raw materials, The
best manufacturing processes. The best quality control systems.

Versatility. No matter what welding positions your job requires, there’s
an Innershield wire specifically designed to handle it. We’ve provided
individual wire descriptions in this brochure that will make it easy for
you to choose the right Innershield product for your needs.
Better portability. Because Innershield is completely self-contained –
with shielding, slagging and deoxidizing materials built right in to the
wire’s core – there’s no need for flux feeding systems or gas bottles.
That means increased portability of your rigs, and more efficient welding operations.
Better feedability. We’ve coated Innershield wire with specially
designed lubricants that keep the wire feeding beautifully – inch after
inch, coil after coil.

Typical Applications
Innersheld wire is a great choice for a wide range of applications,
including:
• Automotive
• Truck & Trailers
• Construction, Farm & Mining Equipment
• Bridges
• Buildings
• Storage Tanks
• Ships & Barges

NOTE: In order to meet the alloy requirements of the G group, the weld deposit needs to have
the minimum, as specified in the table, of only one of the elements marked with an asterisk.

NOTE: NR-212 will not produce weld deposits meeting the minimum Charpy V-Notch impact properties
recommended in the “Seismic Provisions for Structural Steel Buildings” by AISC, dated April 15, 1997.
For these and other applications specifying notch toughness, the following Innershield electrodes should
be considered: NR-203MP, NR-203 Nickel C Plus, NR-203 Nickel (1%), NR-232, NR-305, NR-311 Ni.

A good choice for automatic and
semiautomatic applications. Performs
well on mild steel and some low alloy
steels.
Meets Charpy V-Notch properties.(1)
A constant voltage power source is
recommended.

ADVANTAGE LINCOLN
• Self-shielded, flux-cored. No need
for external gas or flux.
• Produces quality welds in moderate
wind conditions with no tenting.
• Easy slag removal.

RADIOGRAPHIC GUIDELINES
The opacity of NR-203M slag to x-ray is such that slag inclusions will normally appear lighter than the weld.
Voids will normally appear darker than the weld. When using gamma-radiography, slag inclusions and voids will
normally appear darker than the weld. Improved x-ray film readability usually can be obtained by slight overexposure at an excitation potential consistent with good x-ray practice, but not over 240 KV. For detailed
information on welding techniques, procedure adjustments, and their effects on weld appearance and quality,
request publication C3.2400 “Innershield Electrode - Semiautomatic Production Welding Guide”.

RADIOGRAPHIC GUIDELINES
The opacity of NR-203 Nickel (1%) slag to x-ray is such that slag inclusions will normally appear lighter than the weld. Voids will normally
appear darker than the weld. When using gamma-radiography, slag inclusions and voids will normally appear darker than the weld.
Improved x-ray film readability usually can be obtained by slight over-exposure at an excitation potential consistent with good x-ray
practice, but not over 240 KV. For detailed information on welding techniques, procedure adjustments, and their effects on weld appearance and quality, request publication C3.2400 “Innershield Electrode - Semiautomatic Production Welding Guide”.

STORING INNERSHIELD ELECTRODES
In general, Innershield electrodes will produce weld deposits
which achieve hydrogen levels below 16 ml per 100 grams
deposited metal. These products, like other products which
produce deposits low in hydrogen, must be protected from
exposure to the atmosphere in order to maintain hydrogen
levels as low as possible, preventing rusting of the product
and prevent porosity during welding. Accordingly, the following storage conditions are recommended for Innershield
lectrodes in their original, unopened boxes and plastic bags.
The recommended storage conditions are such that they
maintain condition of 90 grains of moisture per pound of
dry air. Examples of storage conditions that will meet this
requirement are given below:

Ambient
Temperature
Fahrenheit

Celsius

Maximum
Relative
Humidity

60° - 70°
70° - 80°
80° - 90°
90° - 100°

(16° - 21°)
(21° - 27°)
(27° - 32°)
(32° - 38°)

80%
60%
45%
30%

Innershield electrodes will evidence high moisture levels in the
form of gas tracks, higher spatter and porosity. Any rusty electrode should be discarded.
Innershield Products Used for Applications Requiring
More Restrictive Hydrogen Control
The AWS specifications for flux-cored electrodes, ANSI/AWS
A5.20, states that “Flux-cored arc welding is generally
considered to be a low hydrogen welding process”. To further
clarify the issue, this specification makes available optional
supplemental designators for maximum diffusible hydrogen
levels of 4, 8 and 16 ml per 100 grams of deposited weld
metal.
Some Innershield products have been designed and manufactured to produce weld deposits meeting more stringent diffusible hydrogen requirements. These electrodes are usually
distinguished by an “H” added to the product name. These
electrodes will remain relatively dry under recommended
storage conditions in their original, unopened package or
container.

For best results, electrode should be consumed as soon as
practicable. However, it may be stored up to three years from
the date of manufacture. Consult your Lincoln distributor or
sales representative if there is a question as to when the
electrode was made.
Once the electrode packaging is opened, Innershield electrodes can be subject to contamination from atmospheric
moisture. Care has been taken in the design of these products to select core ingredients that are essentially resistant to
moisture pick-up; however, condensation of the moisture
from the atmosphere onto the surface of the electrode can be
sufficient enough to degrade the product.
The following minimum precautions should be taken to safeguard product after opening the original package. Electrode
should be used within approximately 1 week after opening the
original package. Opened electrode should not be exposed to
damp, moist conditions or extremes in temperature and/or
humidity where surface condensation can occur. Electrodes
mounted on wire feeders should be protected against condensation. It is recommended that electrode removed from its
original packaging be placed in poly bags (4 mil minimum
thickness) when not in use.

For critical applications in which the weld metal hydrogen
must be controlled (usually H8 or lower), or where shipping
and storage conditions are not controlled or known, only
hermetically sealed packaging is recommended. Innershield
electrodes are available in hermetically sealed packages on a
Special Order basis.
Once the package has been opened, the electrode should not
be exposed to conditions exceeding 80% relative humidity for
a period greater than 16 hours, or any less humid condition for
greater than 24 hours. Conditions that exceed 80% RH will
decrease the maximum 16 hour exposure period.
After exposure, hydrogen levels can be reduced by conditioning the electrode. Electrode may be conditioned at a temperature of 230ºF (110°C) ± 25ºF (-3.8°C) for a period of 6 to 12
hours, cooled and then stored in sealed poly bags (4 mil minimum thickness) or equivalent. Electrode on plastic spools
should not be heated at temperatures in excess of 150ºF.
Electrode that is rusty should be discarded.
