Large range of modular welders planned to carry out multi-spot machines. These welders have been designed mainly to simplify the projects and to reduce the time necessary to accomplish special welders. Each welder can operate independently. When all the welders are connected in cascade mode, it is possible to carry out welding sequences without any outside supervision. The compact dimensions of these welders, assembled with transformer, electronic control, SCR, cylinders, pneumatic system and cooling circuit, allow to carry out versatile multi-spot systems which can be modified with a minimum expense. By sharing the connection of the welders on 3 phases and by welding in sequence it is possible to carry out high productivity machines with minimum power supply from the electric mains.
