Seam welders RT – RL

RT – RL

RT – RL Seam welders range are standard supplied for monophase mains connection. Three phase versions, also with Medium Frequency inverter (1000 Hz), are available for special applications. Medium frequency machine grants high speed welding and enables to join hardly weldable parts with reduced deformation. The wide range of the equipment configurations enables to obtain water tight seam welding of cylinders, fire estinguishers, radiators, tanks and similar items with excellent quality results.

Seam welders

Series of machines with rotating welding discs for water tight lamination seamwelding applications split into RT (transversal welding) and RL (longitudinal welding) models.

SEAM RESISTANCE WELDING

FEATURES

RT models for transversal welding
RL model for longitudinal welding
Water cooled seams heads in mercury bath
Synchronous electronic control (power + spot and pause regulation)
