VAS 821 101A - RESISTANCE SPOT WELDER - 3X400V PTI G
Description:

The VAS 821 101A processor-controlled multifunctional resistance welder with transformer G-clamp is suitable for all repair spot welds permitted on Volkswagen Group vehicles on high- and ultra-high-strength steel sheets and hot-tempered steel sheets (UHSS / Boron steel). It has a maximum electrode contact pressure of 550 daN at 8 bar and a welding power of up to 14,500 amperes.

Existing disturbance factors, such as paint residues, hollow positions, etc. are detected automatically and controlled adaptively wherever possible. If control tolerances are exceeded, a plain-text message appears on the device display. Full process monitoring and automatic control of pressure, welding current or welding temperature is
possible using software. Energy guarantees consistently high-quality welds.

Advantages:
• Lightweight: 11.3 kg with G1 clamp
• Automatic over-opening of 80 mm (20 mm at rest)
• Manual over-opening of arm for access to difficult areas (200 mm clearance)
• Brass clamp holder and arm base for optimum electrical contact (easier maintenance)
• Quick, tool-free arm change thanks to double-action lever
• Automatic cooling liquid connectors
• Remote controls on clamp (over-opening, welding, setting confirmation)
• Ball-bearing-mounted gyroscopic sensor integrated on the clamp
• Maximum productivity (18 points/min)
• G9 arm (optional) with automatic mode

Performance:
• Welding power:
• 14,500 A maximum
