STAVI L - COPPER
The STAVI L - COPPER is the copper version of the L-pattern earth clamp, offered in 200A, 300A and 500A ratings. The copper body and heavy spring give a low-resistance, low-temperature earth connection for continuous welding.
Product details
Key Features and Benefits of STAVI L - Copper Earth Clamp
- Solid Copper Body: Lowest contact resistance in the L-pattern range.
- Three Ratings: 200A, 300A and 500A to suit the machine and cable in use.
- Jaw Opening to 63mm: Opens up to 63mm (2.5in) on the 500A model.
- Heavy Return Spring: Keeps clamping force constant through vibration and movement.
- Runs Cool: Copper conducts the return current with minimal heat build-up.

Frequently Asked Questions
What is the STAVI L-COPPER earth clamp used for?
The STAVI L-COPPER is an L-pattern copper welding earth clamp designed to provide a secure, low-resistance return-current connection. It is suitable for manual arc, MIG and TIG welding, as well as fabrication, structural steel, pipe work, maintenance and repair applications.
What is the advantage of a copper L-pattern welding earth clamp?
The solid copper body provides low contact resistance and efficient current conduction, helping minimize heat build-up at the clamp. Its L-pattern jaw is also designed to seat securely on plate edges, flange faces and angle sections.
What amperage options are available for the STAVI L-COPPER?
The STAVI L-COPPER is available in 200A, 300A and 500A models. They support #2 (35mm²), 2/0 (70mm²) and 3/0 (95mm²) cable capacities respectively.
What is the maximum jaw opening of the STAVI L-COPPER?
The 200A model opens up to 25mm (1.0in), the 300A model up to 38mm (1.5in), and the 500A model up to 63mm (2.5in).
Why does the STAVI L-COPPER have a heavy return spring?
The heavy return spring helps maintain consistent clamping force against the workpiece during vibration and movement. This supports a stable earth connection throughout welding operations.
Is the STAVI L-COPPER suitable for continuous welding?
Yes. Its solid copper body is designed to provide low contact resistance and minimize heat build-up, making the clamp well suited to continuous and demanding welding applications.
