OVERVIEW

Instant Grounding, Zero Hassle

Every welder knows the frustration of trying to find a good spot for the ground clamp. You're working on a large steel plate, the middle of a pipe, or a tank wall, and there isn't an edge within reach for your standard spring clamp. You end up tacking on a temporary tab just to get a ground, wasting time and material. The Bessey 800 Amp Magnetic Ground Clamp (MGC-2) eliminates this headache entirely. If the metal is magnetic, you have a ground point. Just place the clamp right next to your weld zone, and you are ready to strike an arc.

Power to Spare
Don't let the compact design fool you; this clamp is a beast. Rated for 800 amps, it can handle the heat of your most demanding jobs. Whether you are burning heavy rod or running thick flux-core wire, this magnetic ground ensures the current flows smoothly. The strong magnet pulls the contact face tight against the metal, creating a solid electrical connection that prevents the sputtering and arc wander caused by weak grounds. Because it has a large surface area touching the metal, it runs cooler than point-contact clamps, meaning it lasts longer and won't burn up your cable connection.

Built for the Shop
Bessey tools are legendary for their durability, and this magnetic ground is no exception. It is designed to be tossed in your tool bucket, dragged across the shop floor, and used day in and day out. The setup is simple: bolt your ground cable lug to the terminal, tighten it down, and you are set. It's an essential problem-solver for any welder working with steel. Stop fighting with your ground lead and start welding faster with the convenience of magnetic adhesion.

FAQ

The Bessey MGC-2 is rated for up to 800 Amps, making it suitable for heavy-duty industrial welding applications.

No, this is a magnetic ground clamp and requires a ferromagnetic surface to attach. It will not stick to aluminum and will not stick to most grades of stainless steel.

The clamp features a bolt/stud connection point where you attach a standard cable lug. You will need a cable lug crimped to your welding lead to bolt it securely to the device.

All magnets can lose strength if exposed to extreme heat (Curie temperature), but under normal welding conditions, if the ground is placed appropriately away from the immediate weld pool heat, it maintains its holding power.

It is not necessarily 'better' but serves a different purpose. It is superior for flat surfaces or large areas where there is no edge to clip a spring clamp onto. A spring clamp is better for non-magnetic metals.

Magnetic grounds can sometimes contribute to arc blow if placed too close to the arc, but this is generally manageable. Positioning the ground clamp correctly relative to the direction of travel helps mitigate this.

No, the MGC-2 is typically a permanent magnet design without a mechanical release switch. It is removed by tilting or sliding it off the workpiece.

The large contact area reduces electrical resistance at the connection point. Lower resistance means less heat generation and better current flow, which is crucial for high-amperage welding.
