Welding magnetic ground clamp YATO YT-08625 7 kg holding force 500 A current capacity

Magnetic welding ground clamp YATO YT-08625 combines a magnetic attachment and conductive clamp body to provide a stable grounding point for arc welding. The tool offers a holding force rated at 7 kg and supports welding currents up to 500 A, allowing secure contact with ferrous workpieces and reducing the risk of slipping or intermittent electrical connection during welding operations. Its compact design suits both stationary workshop use and mobile welding tasks, helping to speed up setup and maintain consistent arc performance.

Advantages

The magnetic clamp provides a firm magnetic hold to keep the grounding connection in place without the need for mechanical clamps or fixtures. With a current capacity of up to 500 A it supports common MMA and MIG welding tasks within that range. The compact and portable construction allows quick positioning on steel surfaces, improving setup time and reducing the chance of poor electrical contact. The design reduces movement of the workpiece relative to the ground connection, contributing to a more stable arc and more consistent weld quality.

Suitable for

• Grounding ferrous metal workpieces during MMA, MIG and TIG welding within the clamp's current rating
• Workshop and site welding where temporary, repositionable ground connections are needed
• Mobile or on-vehicle welding tasks that require rapid attachment and detachment
• Situations where reducing setup time and preventing clamp slippage are important

Key specifications

• Magnetic holding force: 7 kg
• Maximum welding current capacity: 500 A
• Application: attachment to ferrous steel surfaces
• Construction: magnetic base with conductive clamp body for electrical grounding
• Portability: compact, suitable for workshop and mobile use

How to use

Select a clean, flat area on the ferrous workpiece and attach the magnetic clamp so the magnetic base sits flush against the metal surface. Ensure the contact area is free of heavy rust, paint, or scale to improve electrical conductivity; light surface cleaning may be necessary. Connect the welding cable to the clamp's conductive terminal according to the welding machine manufacturer's guidance, then position the clamp to minimize cable tension and movement during welding. Periodically check the clamp's contact and magnetic seating during long welds to maintain steady current flow.

Usage recommendations

For reliable performance, use the clamp within its 500 A rating and attach it to clean ferrous surfaces. Avoid using the magnetic clamp on non-ferrous materials or relying on painted or heavily corroded surfaces for electrical contact. When welding at higher currents or in critical applications, verify that the clamp's contact area remains secure and consider using supplementary grounding methods if required.
