DK 250-P1

With a Compressive Force of 400 / 800 N for Capacitor Discharge and Medium Frequency Welding

The double welding heads of the DK-25-PSA series have proven themselves for many years in automatic welding machines.
We have re-engineered the design, adapted it to the newest requirements and matched it to the customer’s needs.
The new redesigned DK 250-P1 features the same installation dimensions as its predecessor DK 25 PSA-P1.
The two models are compatible in every respect and may be interchanged without any problems.
