Component Specifications

Definition
A precision mechanical clamping device designed to securely hold and position welding electrodes or EDM electrodes during operation. It ensures stable electrical contact, proper alignment, and efficient heat dissipation while allowing quick electrode changes. The clamp maintains consistent pressure to prevent arcing, slippage, or misalignment during high-current applications.
Working Principle
Operates through mechanical leverage (often via screw, spring, or cam mechanisms) to apply controlled clamping force on the electrode. This creates a secure electrical connection while allowing for thermal expansion and vibration damping. The design ensures minimal resistance at the contact point for efficient current transfer.
Materials
Copper alloy (typically C11000 or C17200) for conductivity, with stainless steel (304 or 316) for structural components. Insulation parts use ceramic or high-temperature polymer. Contact surfaces may have silver plating for enhanced conductivity.
Technical Parameters
  • Clamping Force 50-200 N
  • Temperature Range -20°C to 200°C
  • Contact Resistance < 0.5 mΩ
  • Max Current Rating 600 A
  • Insulation Resistance > 100 MΩ
  • Electrode Diameter Range 1.6-6.0 mm
Standards
ISO 5821, ISO 5828, DIN 43125
