Low carbon steel welding rod for oxy-acetylene welding. It is a general purpose rod for
welding low carbon steels and wrought iron with the required tensile strenght does not exceed
310 N/mm². Generally used for automotive repair works like tears and rips in the body or
patching on badly damaged parts, joining steel sheets and plates, tubing and piping
installation where and intense heat source is required for straightening, forming, preheating
post weld heat treatment, regardless of the complexity and position in which welding has to
be done. Weld metal has got good ductility and machinability. Welding shall be performed in
neutral flame characteristics. It has got a fluid weld puddle.

Low carbon steel welding rod, for oxy-acetylene gas welding, containing slightly higher
manganese. It is a general purpose welding rod with medium strength, used for welding carbon
steels and low alloy steels with tensile strenghts up to 410 N/mm². Commonly used for carbon
steel pipe installation and repair works in power plants, process piping, machine and agricultural
tool repair, joining steel plates and wrought irons, filling holes and edged on wrought iron,
where an intense heat source is required for straightening, forming, preheating post weld heat
treatment, regardless of the complexity and position in which welding has to be done. Welding
shall be performed in neutral flame characteristics. It has got a fluid weld puddle.

GTA (TIG) welding rod for unalloyed steels, fine grained steels and pipes. Particularly suitable
for welding of galvanized and pre-painted steels, welding low alloy steels in pipe-lines, boilers
and tank production. Used in root and cap passes in chemical, petrochemical, water, natural
gas pipes joints safely. Suitable also welding in thin metal plates and repair welds.
Characterized by a reduced slag formation and smooth welding deposit. Thin and
homogeneous copper coating increase resistance to rusting.

Micro-alloyed, GTA (TIG) welding rod for unalloyed steels. Due to its titanium (Ti) and
aluminium (Al) micro alloy contents, particularly suitable for single pass welding of galvanized,
pre-painted, rusty and dirty steels, welding low alloy steels in pipe-lines, boilers and tank
construction. Suitable also welding in thin metal plates and repair welds. Thin and
homogeneous copper coating increase resistance to rusting.
