INVERTER SPOT WELDING SYSTEM SHELLMAX-12
• Bilingual
• Double pistons cylinder
• Ideal for car-body works and serial productions
• Customisation of any stored spot welding programs
• Operation with pneumatic clamp, manual and studder welding.
• Senses the voltage and auto-compensates for the power source.
• Control and regulation of all the steps of the spot welding process
Microprocessor controlled, three-phases, inverter (MFDC 2000 Hz) resistance welding.
Automatic control of the spot welding current (12.000 A) continuous and pulse operation
High efficiency and productivity improved in comparison with the traditional resistance welding systems
Over 200 pre-set programs according to the kind and thickness of the material used and to the kind of clamp chosen.
High quality and aesthetic of the spot on all kinds of high resistance steels,HSS,AHSS, galvanized steels and stainless steels
Standard equipment: water cooled clamp and air cooled cables, built-in water cooling system, arm and balancer to hold the clamp
Control Panel: Use a large 5x7” monitor to display images and clip art and software is stored on an upgradeable CPU by internet.
