VOREL ZKB-35 74420 Welding Earth Clamp
A welding earth clamp is a component of the welding circuit used to close the electrical circuit by connecting the cable to the workpiece. The ZKB-35 model, fitted with a spring-loaded jaw mechanism, provides a secure connection for 35 mm² welding cable.
Welding earth clamp features
Spring-loaded jaw mechanism
The clamping system ensures stable electrical contact with the workpiece. The spring-loaded jaws allow quick attachment and release without additional tools, which speeds up changes between working positions.
160 A welding current
This parameter defines the maximum continuous operating current that can flow through the clamp without risk of overheating. At 160 A, steel plates up to 6-8 mm thick can be welded, depending on the welding method.
35 mm² cable cross-section
The cable entry is sized for 35 mm² welding cable. A larger cable cross-section means lower electrical resistance and less energy loss during welding, which translates into a more stable welding arc.
Jaw opening up to 50 mm
The maximum jaw opening allows the clamp to be attached to components up to 50 mm thick. This is an important parameter when working with profiles, pipes or thicker plates, where the clamp has to grip a larger surface area of material.

Applications of the welding earth clamp
- MMA (Manual Metal Arc) welding as the earth connection
- MIG/MAG welding as the earth for the workpiece
- TIG welding as the earth connection
- Securing the earth cable to a welding bench
- Connecting the electrical circuit to workpieces of various shapes
- Assembly work requiring frequent repositioning of the clamp
- Welding steel structures, profiles and pipes
- Welding repairs to machine and equipment components
Use and maintenance
Choosing the welding cable
The clamp is designed for 35 mm² cable. When welding at 160 A with a cable length of up to 10 metres, a 35 mm² cross-section provides adequate conductivity. For longer cables (over 10 m), a larger cross-section is recommended in order to minimise voltage drop.
Maintaining electrical contact
Regularly check the condition of the clamp jaws for wear and build-up. Contaminated or damaged jaws increase contact resistance, which leads to overheating of the clamp and an unstable arc. Clean the contact surfaces with a wire brush, removing oxides and scale.
Attaching to the workpiece
Attach the clamp to a clean, unpainted metal surface. A layer of paint, rust or oxides increases electrical resistance and can cause problems with arc striking. On galvanised or painted components, clean the surface under the clamp back to bare metal.
