VAS 821 101 Resistance Spot Welder 3x 400V (4M)

VAS 821 101 Resistance Spot Welder with C-clamp and transformer in the clamp

The multifunction Resistance Spot welder VAS 821 101, with transformer integrated in the clamp, microprocessor controlled, fulfills the requirements for the repair of Volkswagen group vehicles for the welding of High and Ultra High strength steels (UHSS / Boron steel). Maximum clamping force of 550 daN under 8 bar. Maximum welding current of 14 500 A even with weaker electrical supply (the machine delivers around 9000 A on an installation with 16 A circuit breaker, and the maximum power on an installation with 25 A, or higher, circuit breaker). The presence of non-conductive elements like residues of paint, porosity, etc…. is recognized by the automatic mode and compensated by an automatic modification of the welding parameters. When tolerances are exceeded, a message appears on the screen of the machine. The complete supervision of the welding process and the automatic setting of the electrode force, welding current and energy, guarantees high quality welding spots in all circumstances.

Advantages:

• Liquid cooled medium frequency transformer integrated in the clamp
• Lower electricity consumption (40% less than cable machine)
• Operating from 16 Amps power supply (with delayed fuses)
• High duty cycle
