The car shock absorber resistance welder comes equipped with a Heron 45KJ power supply and is also outfitted with a custom fixture system.

In the past, car shock absorbers were welded using single-phase or three-phase rectifier welding, which resulted in significant efficiency waste. We improved upon this problem by introducing a 45KJ capacitor discharge welding machine that only needs a 100KVA power supply. This reduces power supply needs and it can also realize 8 welding spots on both sides with a decreased heat affected zone, leading to a high quality weld.
