Welding clamp Vorel ZKB-70 (model 74421) — hold-down kleszczowy clamp

Vorel ZKB-70 welding clamp (model 74421) is a kleszczowy hold-down clamp designed to secure metal parts during welding and fabrication. The clamp provides a firm mechanical grip that helps maintain alignment and consistent contact between workpieces. It is intended for use in spot welding, tack welding and general workshop joining tasks where a stable, repeatable clamp force is required.

Advantages

The Vorel ZKB-70 delivers a robust clamping action with a simple pincer mechanism that is easy to position and operate. Its compact construction allows access to confined or close-tolerance joints while maintaining reliable pressure. The clamp resists slipping under heat and vibration typical for welding environments, and its mechanical design requires no external power to hold parts together, ensuring predictable behavior during welding cycles.

Suitable for

• Spot welding of sheet metal components
• Tack welding and temporary assembly in fabrication
• Holding small to medium-sized workpieces during alignment and joining
• Workshop fixtures and repeatable clamping operations

Key specifications

• Type: kleszczowy (pincer) hold-down welding clamp
• Primary function: mechanical grip for welding and assembly
• Construction: compact metal body suited for workshop use
• Suitable materials: steel and common ferrous sheet metals
• Typical applications: spot welding, tack welding, temporary fixturing

How to use

Position the Vorel ZKB-70 clamp so the jaws engage the workpieces at the desired weld point, ensuring proper alignment and electrical contact if used for spot welding. Apply the clamp’s pincer action to achieve a firm hold without deforming thin material. Verify that the clamp jaw faces are clean and free of scale or debris to ensure consistent pressure and contact. During welding, maintain awareness of heat transfer to the clamp and reposition or allow cooling as needed between cycles.

Usage recommendations

For reliable results, use the clamp on appropriately prepared metal surfaces and avoid over-tightening on thin sheets to prevent distortion. Inspect the clamp regularly for wear on jaw faces and for secure fastenings, and replace or service components showing significant wear. When performing electric spot welding, ensure safe grounding and follow welding equipment guidelines to prevent unintended current paths through clamp hardware.
