Tweco GC-200 Ground Clamp

The Tweco GC-200 ground clamp is built for welders who need a reliable 200 amp connection on flat work surfaces. Its copper body and insulated spring deliver consistent conductivity for everyday arc welding tasks.

Copper body with ball-point screw

The clamp body uses copper for low resistance while the ball-point screw secures cables up to 1/0 AWG without damaging strands. A one-inch jaw opening and three-inch throat depth let it grip flat plates quickly in the shop.

Arc flash protection and heat management

The insulated spring and HAWA material help contain arc flash energy during strikes. Copper construction spreads heat across the clamp so it stays cool enough for continuous 200 amp runs without overheating.
