arc electric welding is the most diffused and well-known
welding technology. In this field ISEA produces welding dynamo with and
without auxiliary generator.
These machines are intended to be combined to thermal engines to realize
weldings motion, or to be mounted on pipe heating tractors.
The arc welding machines are also used in the countryside in the realization of aqueducts, oil
pipelines, gas pipelines, etc. ISEA also produces converter groups for
arc welding established by a welding dynamo moved by an electric
