Resistance spot welding machine VAS 821 101A
The processor-controlled multifunction resistance spot welding machine VAS 821 101A with transformer G-clamp is suitable for all repair spot welds on high-strength, ultra-high-strength and hot-form-hardened steel sheets approved for Volkswagen Group vehicles
(UHSS/BTR).
Maximum electrode contact pressure of 550 daN at 8 bar.
Welding power up to 14,500 amps. Existing disturbance variables such as paint residues,
hollow layers, etc. are detected in automatic mode and adaptively corrected as far as possible.
This welding machine is intended for connection to the USA mains.
