GM205 - Strong Hand PowerBase 500A Switchable Magnetic Ground Clamp

Strong Hand Tools GM205 PowerBase Magnetic Ground Clamp

Grounding is a critical component of the welding circuit, yet it is often the most overlooked aspect of setup. The Strong Hand Tools PowerBase Magnetic Ground Clamp (GM205) revolutionizes how welders establish a ground connection, particularly on large fabrications where finding a suitable clamping edge is difficult or impossible. Unlike traditional spring-loaded clamps that require a protruding edge or a tacked-on tab, the PowerBase magnet attaches directly to the workpiece surface, offering unparalleled flexibility in shop environments.

At the heart of the GM205 is a powerful rare earth magnet capable of delivering 110 lbs of holding force. This ensures that the clamp stays firmly in place, preventing accidental disconnections that can lead to arc instability or weld defects. The unit is rated for heavy-duty industrial use, boasting a capacity of 500 Amps at a 60% duty cycle. This makes it suitable for high-amperage MIG, TIG, and Stick welding applications where consistent current flow is mandatory.

One of the standout features of this magnetic clamp is its intelligent design catering to various material shapes. The contact face features a machined "V" groove, specifically engineered to grip round parts such as pipes, tubes, and shafts securely. This eliminates the wobble often associated with placing flat magnets on curved surfaces. Furthermore, the inclusion of a copper connector stud ensures maximum electrical conductivity, reducing resistance and heat buildup at the connection point.

Efficiency is further enhanced by the On/Off switch mechanism. With a simple turn, the magnetic force is engaged or disengaged. This not only makes setup instant but also simplifies maintenance; when the magnet is turned off, metal shavings and grinding dust simply fall away, keeping the contact surface clean for the next job. Whether you are working on large plates, pressure vessels, or structural steel, the Strong Hand GM205 provides a reliable, high-performance grounding solution.
