OVERVIEW

Industrial Grade Grounding Solutions

The Tweco GC-300 Ground Clamp is a staple in the welding industry, renowned for its durability and electrical efficiency. This specific offering is a Master Pack of 24, designed specifically for large-scale fabrication environments, MRO supply rooms, and welding schools that require consistent, high-quality grounding across multiple stations. The GC-300 is engineered from a high-copper alloy, which provides superior conductivity compared to stamped steel alternatives. This ensures that the welding circuit maintains minimal resistance, reducing heat buildup at the contact point and preserving the integrity of the clamp over long-term use.

Efficient grounding is critical for protecting expensive welding power sources and ensuring consistent weld quality. The GC-300 features a ball-point cable connection system, which allows for a secure mechanical termination of the welding cable (up to 3/0 size) without the need for specialized crimping tools, although proper installation is key. The heavy-duty spring mechanism delivers substantial holding power, ensuring the jaws bite through light rust or scale to establish a solid electrical connection. For procurement managers and facility supervisors, purchasing the GC-300 in a master pack simplifies inventory management and ensures that replacement units are always on hand to minimize downtime.

This clamp is rated for 300 Amps at a 50% duty cycle, making it suitable for a wide range of MIG, TIG, and Stick welding applications in manufacturing and repair sectors. The jaw design allows for a 1.5-inch opening, providing versatility for clamping onto various shapes of workpieces, from plate steel to pipe. By standardizing on the Tweco GC-300, facilities ensure safety and performance consistency across their operations.

FAQ

The Tweco GC-300 ground clamp accepts welding cable sizes up to 3/0 AWG.

It is rated for 300 Amps at a 50% duty cycle.

This is a Master Pack containing 24 individual GC-300 ground clamps.

The jaws are constructed from a high-conductivity copper alloy.

It uses a ball-point screw connection that secures the cable strands firmly without damaging them.

The jaws open up to approximately 1.5 inches (38mm).

Yes, provided the amperage is within the 300A limit, the copper construction provides the stable ground required for TIG welding.

While Tweco offers replacement parts for many products, ground clamps of this size are typically replaced as whole units when the spring or jaws wear out.
