The 2 pack welder magnetic ground clamp is a pair of magnet-based ground connectors with a copper tail, listed for ARC, MIG, flux core and stick welding. Each is listed at up to 3 kg of holding force, so it is a light-duty option. It works on clean, bare, magnetic steel and is not a substitute for a heavy-duty jaw clamp.
Quick verdict
Best for: Quick ground connections on clean steel for hobby, repair and portable jobs.
Main limit: A magnet only grounds as well as the contact. The listing gives no amp rating, so do not use it for high-current work until you confirm one.
What the 2 pack welder magnetic ground clamp is
Instead of gripping an edge, each clamp sticks to a steel surface and carries welding current through the magnet contact and its cable tail. That saves time when the part has no convenient edge. The weak point is the contact patch, so the clamp has to sit flat on bare metal.

Who should buy it, and who should skip it
- Good fit: small repairs, thin tacking and mobile jobs on clean steel where a spring clamp is awkward.
- Skip it if: you weld at high amperage, on painted, rusty or non-magnetic metal, or in wet conditions. Use a jaw-style clamp like the one in the T-style welding ground clamp review.
How to use a magnetic ground clamp
- Grind or wire-brush the spot down to bare, clean metal.
- Place the clamp flat so the whole magnet face touches.
- Connect the tail to your ground lead, making sure it is tight and not near the arc.
- Tack a test bead and check the arc is stable.
- After a few welds, touch the clamp carefully. If it is hot, stop and use a jaw clamp.
- Keep it away from heat and spatter, and wipe off metal dust, because the magnet attracts it.
Safety: A poor ground can arc at the contact and overheat the clamp. Do not rely on the magnet to hold the part, and keep magnets away from pacemakers and electronics.
Pros and limitations

Frequently Asked Questions
Can I use these clamps outdoors in wet conditions?
Be careful. Moisture reduces contact quality and raises electrical risk. Keep the contact area dry and follow your welder manual.
How do I clean and maintain them?
Wipe off metal dust and spatter, keep the magnet face clean and flat, and check the tail and connection for wear or heat damage before each use.
What safety precautions should I take?
Attach the clamp to clean bare metal, never to painted, rusty or oily spots, and confirm the ground is firm before you weld. Keep magnets away from medical devices.
What is the warranty?
It is not stated in the listing text I could review. Check the Amazon page and seller terms.
Do they work with all welding machines?
The listing names ARC, MIG, flux core and stick welding. Confirm that the cable connection suits your welder and that the clamp is rated for your current.
The bottom line
This 2 pack of magnetic welding ground clamps is handy for light work on clean steel. Confirm the amp rating with the seller before you use it for anything demanding.
