All you need
– Elga coated electrodes
Still going strong
Welding with ”stick” electrodes is a traditional and
reliable welding method. It has many advantages and
is superior to MIG/MAG/TIG welding, when used under
the right circumstances.
Use coated electrodes
When you don’t want to handle shielding gas at
the site.
– The cost of shielding gas can be as large as
the cost of welding consumable.
When you don’t want to use advanced and heavy
welding machines.
– Large and complicated welding machines
are often expensive. They also require maintenance of wear parts and conduits.
When you want great flexibility and short set-up
– The light and simple equipment is portable
and easy to move between different work
places and work levels.
When you work in restricted spaces
– With coated electrodes and a small inverter
it’s easier to weld when it’s cramped.
When it’s hard to protect the site
– MIG/MAG/TIG-welding requires the working site to be protected from the wind, which
can be both time consuming and costly.
All you need
Coated electrodes
from Elga and a
small inverter.
Rutile or basic coated electrodes
Rutile electrodes
+ User friendly.
+ Easy to strike and re-strike.
+ Produce minimum spatter.
+ Self-detaching slag.
+ Electrodes for both positional and horizontal
Be aware of
Should not be used for alloy steels with yield
strength above 355 MPa because the hydrogen
content for rutile electrodes is >20 ml/100 g weld
Should not be used for welds that are to be stress
The chemical composition of the
electrode coating determines if the
electrode is “rutile” or “basic”.
Basic electrodes
The most common
electrode type
+ Can be welded in all positions and are often used as an all-round electrode.
+ High weld quality with excellent toughness and impact strength.
+ Good protection against hydrogen cracking as a result of low moisture content.
+ The only electrodes suitable for un- and low
alloyed steels when good impact strength is
required at temperatures below -20 OC.
Be aware of
Not as easy slag detachment as rutile electrodes.
The surface is not as smooth as rutile electrodes
and the profile is often convex.
High recovery
- A profitable alternative
To increase productivity iron powder is added to
the coating, which gives significantly higher recovery and productivity than normal metal recovery
Normal metal recovery electrodes:
98-120 % recovery
High recovery electrodes:
120-240 % recovery
High recovery electrodes:
Preferable for horizontal welding in PA and PB positions.
Can also be suitable when welding
horizontal-vertical (PC position).
Slightly higher current is necessary com-
pared to normal metal recovery electrodes.
Many Elga electrodes are packed in DryPac. The
special vacuum packaging prevents moisture absorption from the surrounding atmosphere and comes in
smaller sizes than normal packets.
Elga’s high recovery electrodes for un- and low
alloyed steels have the generic title Maxeta. By using Maxeta you increase productivity and improve

P 45S
Basic electrodes
P 45S is a welder friendly all-round electrode. It produces a weld with excellent
cosmetic finish using both AC and DC
(for DC preferable – pool). Also suitable
for tack welding and for welding in thinner materials.
Welding position: Welds in all positions,
including vertical down.
Advantages: Minimum spatter, smooth
bead surface and self-detaching slag. Easy
to strike and re-strike.
Maxeta 11
High recovery
Maxeta 11 is the high recovery alternative to a normal rutile electrode and gives
you significantly greater productivity in
horizontal welding. It also gives a good
result on primed plates.
Application & welding position: Downhand and horizontal-vertical fillet welds
and horizontal butt welds.
(N.B. The 4.0 mm electrode requires
welding current greater than 180 Amp)
Advantages: Excellent slag removal,
minimum spatter, smooth bead surface,
easy to strike and re-strike. AC / DC.
P 48S – all-round electrode
P 48S is an all-round 7018-electrode.
Welding with P 48S means problem
free welding, as the basic weld metal is
tough and contributes to good mechanical
Application & welding position: For all
applicable joint types and root passes. All
positional, except vertical down. Can also
be used for highly restrained joints as it
gives a low impurity, tough weld metal.
Advantages: Good welding characteristics, low risk of cold cracks and high
productivity for a 7018-electrode.
P 48M SiteMaster™
Excellent all-round electrode for site work
and pipe welding.
Application & welding position: Buttand fillet welds, root- and fill passes in all
positions except vertical down.
Advantages: Extremely user friendly with
a very stable arc. Easy to strike and restrike. Insensitive to voltage drops. Ideal
for small inverters.
Maxeta 20
High recovery
Maxeta 20 is the high recovery alternative
to a normal basic electrode. It is the best
choice of high recovery electrode for impact strength requirements down to -20oC
and low hydrogen level.
Maxeta 20 gives a good cosmetic finish
weld and reduction in post-weld dressing
(deslagging/grinding) resulting in good
welding economy.
Application & welding position: Butt
and fillet welds in PA, PB and PC positions.
Advantages: Produces a smooth, mitre
profile fillet and smooth transition with
base material as well as self-detaching
slag. It is also easy to make extended run

Cromarod is Elga’s electrode family for
stainless steel welding. First, you choose
electrode to match base material composition. Second, the right type should be chosen i.e. all-round operability electrode or
LP-electrode for optimal positionality.
Cromarod all-round electrodes
Cromarod 308L, 316L and Cromarod
Duplex are typical all-round electrodes
and easy to use.
Application & welding position: Welding of all applicable joint types and root
passes in all positions except vertical
Operability limitations: Not suitable
for root passes on thinner materials. Cromarod LP-electrodes are recommended
here instead.
Advantages: Smooth bead surface,
self-detaching slag and minimal spatter.
Easy to strike and re-strike. DC+ recommended.
Cromarod LP-electrodes for
positional welding
Cromarod 308LP, 316LP and Cromarod
Duplex LP are common LP-electrodes for
pipe welding. Its user friendly properties
makes Cromarod LP the ultimate choice
for stainless steel positional welding.
Application & welding position: Welding of thin sheet and thin walled pipes
(down to 2.0 mm). The electrode can be
used to advantage for root passes and positional welding in thicker material. Also
good for tack welding. Excellent in all
positions, even vertically down.
Operability limitations: Not the best
choice for fillet welds; use ordinary Cromarod instead.
Advantages: Gives excellent bead shape,
self-detaching slag and is easy to strike
and re-strike. Cromarod LP is also good
at low current levels. DC+ recommended.
Easily bridges gaps up to 6.0 mm (using
Basic Stainless
Elga’s basic stainless electrodes are specially designed for higher toughness, low
temperature requirements. Increased gas
shield due to the higher carbonate content
makes them especially suitable for windy
conditions on the site.
The Cromarod electrodes give excellent bead shape and self-detaching
