Spot welder 4050

electronic

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. Rocker arm welding unit with with TE93 microprocessor welding control unit. Adjustable arms up to 320 mm, enabling to adjust the welder according to the work exigencies. Chrome-copper electrode-holders for heavy duty and long life, designed for both straight and angled assembling. Adjustable electrodes stroke, enabling to reach the max. working rate. Water-cooled transformer, with epoxy resin coated windings. Water cooled arms, electrode-holders and electrodes. Synchronous SCR contactor insulated from cooling water circuit with protection thermostat. Double effect pneumatic cylinder, lubrication free against oil mist.
