The Magnetic Ground Clamp is a 250-amp welding ground clamp that attaches instantly to ferrous metal surfaces using powerful magnetic force. Designed for heavy-duty welding applications, this clamp eliminates the need for traditional screw-down or lever-style clamps, providing fast, secure grounding on base metal without surface preparation.
Built for professional welders and fabricators, this magnetic ground clamp features a 3-1/2" diameter magnetic base that creates strong holding force on flat or curved steel surfaces. The classic rail profile design ensures compatibility with standard welding cable connections, while the magnetic attachment allows you to reposition the clamp quickly between welds. The 1/8" recess and 5/8" bore accommodate standard welding cable lugs for reliable electrical contact.
Magnetic Attachment — Instant connection to ferrous metal surfaces; no clamping mechanism required.
3-1/2" Diameter Base — Large magnetic contact area provides strong holding force on flat or curved workpieces.
Classic Rail Profile — Standard cable connection design works with existing welding cable setups.
No Surface Prep Required — Attaches directly to base metal surfaces without grinding or cleaning.
Quick Repositioning — Magnetic design allows fast relocation between weld joints.
Applications
Used by welders, fabricators, and metal shop professionals for MIG, TIG, and stick welding operations. Ideal for structural steel fabrication, equipment repair, pipe welding, and general metalworking where frequent ground clamp repositioning is required. Particularly effective on large workpieces where traditional clamps are difficult to attach.
