GMS300 - High-Temp Magnetic Spring Ground Clamp


  • - Magnetic Welding Ground Clamp. A device that speeds up grounding chores for welders
  • - No-hassle Safety Setup: This device serves as the ground point, which you can take with you anywhere. Simply tack this onto a convenient spot, hook up your safety wire and you're ready to weld
  • - Strong Magnetic Grip: This magnetic clamp attaches easily to any smooth metal surface, flat or curved. It holds on tightly, without budging easily
  • - High-Temperature Resistant Magnets: It can withstand short-term temperatures of 572°F (300°C) and long-term temperatures of 356°F (180°C). Stable and durable in high-temperature environments.
  • - Strong magnetic attraction force: The magnet has a maximum attraction force of 60 lb (30 kg)
  • - This magnetic clamp is very convenient, you can stick in on a car body and not have to damage the paint; The clamp can also be attached to metal poles, struts, railings or the welding table
  • - Material: Copper / insulation board. Durable and solid. With copper tail with good welding stability
  • - Adaptable to uneven welding surfaces: Equipped with a strong spring structure, the pure copper conductive pillars fit tightly against the workpiece surface, adapting to uneven welding surfaces.

Features

Welding process with sparks and smoke on a work table.

Fast, Anywhere Grounding

Set up your ground point in seconds. Just place the magnetic clamp on any metal surface, connect your lead, and you’re ready to weld, no extra prep or hassle.

Powerful Magnetic Hold

Delivers up to 60 lb (30 kg) of holding force. Attaches securely to flat or curved metal surfaces and stays firmly in place during welding.

Built for High Heat

Engineered with high-temperature resistant magnets that withstand up to 300°C short-term and 180°C long-term use, reliable performance in demanding environments.

Welding tool clamped to a metal pipe on a work surface.

Reliable Contact on Uneven Surfaces

Spring-loaded copper conductive pillars ensure tight, consistent contact, even on rough or irregular workpieces, for stable current flow and better weld quality.
