& SELECTION CHART
CIGWELD WIA LIQUIDARC ESAB
IRON
POWDER
ESH160R
Heavy coated, rutile type high efficiency electrode having a weld metal recovery of
approx. 165%. Is preferred for economically filling of large weld sections and long
fillets. Produces very smooth, concave and clean welds, merging into base metal
without undercuts. Suitable for welding pre painted and galvanized plates. Easy arc
striking and restriking. Slag is self-releasing in most cases.

EI 308L
Electrode for welding austenitic stainless Cr-Ni steels or cast steels, having an
extra low carbon content, as well as stainless or heat resisting chromium steels or
cast steels. Suitable for welding stainless steel tanks, valves, pipes and linings in
chemical, food industries. For operating temperatures of up to +350˚C, non-scaling
up to +800˚C. Possible to use equally well both with AC and DC. Easy arc striking
and restriking. Fine metal droplet transfer, good fusion of joint faces, finely rippled
bead surface, easily removable slag.
EIS 309Mo
High-efficiency electrode for welding dissimilar steels (ferritic to austenitic steels)
and depositing austenitic stainless claddings. Weld metal recovery of 160 %. The
austenitic weld metal has a delta-ferrite content of approx. 15 %. Claddings on
unalloyed steels are already corrosion resistant in the first layer. Highest operating
temperature for dissimilar steel joints is +300°C. Possible to use equally well both
with AC and DC. Easy arc striking and restriking. Fine metal droplet transfer, good
fusion of joint faces, finely rippled bead surface, easy slag removal. High current
carrying capacity, since core wire is not made of stainless steel.
EI 312
Electrode for joining dissimilar steels and depositing claddings on ferritic steels.
The ferritic-austenitic Cr-Ni weld metal contains approximately 50% of delta-ferrite
and is non-scaling up to +1100˚C. It features high resistance to cracking and is
therefore suited for joining difficult to weld steels and depositing stress-relaxing
buffer layers on crack sensitive base metals. Suitable for welding galvanized steel
plates. Possible to use equally well both with AC and DC. Easy arc striking and
restriking. Fine metal droplet transfer, good fusion of joint faces, finely rippled bead
surface, easy slag removal
EI 316L
Electrode for welding austenitic stainless Cr-Ni-Mo steels or cast steels, having an
extra low carbon content. For operating temperatures of up to +400˚C. Especially
suitable for welding of stainless steel chemical tanks and pipes in chemical, textile,
paint, paper industries. Possible to use equally well both with AC and DC. Easy arc
striking and restriking. Fine metal droplet transfer, good fusion of joint faces, finely
rippled bead surface, easily removable slag.

CAST IRON
ENI-416
Electrode having a nickel-iron core wire for welding cast iron with or without ­
preheating. The weld metal features a low coefficient of thermal expansion and
as a result , little shrinkage. It has higher strength properties than pure nickel weld
metal and is therefore preferable used for welding nodular cast iron, white and
black heart malleable cast iron, as well as austenitic nodular cast iron or joining
these metals to components made of steel, copper or nickel materials. Easy arc
striking and restriking, stable arc, smooth bead. Weld metal is machinable. Weld
short beads.
ENI-402
Electrode having a pure nickel core wire for welding cast iron without or with low
preheating (max. +300˚C). For repair welding of cracked cast iron parts or joining
components made of steel, copper or nickel materials to castings. Electrode suited
to welding cast iron with lamellar graphite, white and black heart malleable and
nodular cast iron. Easy arc striking and restriking, stable arc, smooth bead surface.
Weld short beads, about 30 to 50 mm long. In order to reduce weld residual
stresses, hammer-peen welds slightly before cooling. Weld metal is machinable.
Preferably used with DCEP but possible to use also with AC.
