WWWWGC-600 - 600 Amp C-Style Heavy Duty Welding Ground Clamp

High-Performance 600A Grounding Solution

The WGC-600 Ground Clamp "C" 600Amp is a premium-grade welding accessory designed for industrial applications requiring reliable, high-amperage grounding. Unlike standard spring-loaded clamps, this C-type (or G-type) clamp utilizes a threaded screw mechanism to deliver exceptional clamping force. This mechanical advantage ensures a tight, low-resistance connection to the workpiece, which is critical for maintaining stable arc characteristics and preventing voltage drops during heavy welding operations.

Constructed from a durable high-conductivity copper or brass alloy, this clamp is engineered to handle up to 600 amps of current without excessive heating. The substantial mass of the clamp acts as a thermal sink, while the broad contact surface area facilitates efficient electron transfer. This design minimizes the risk of "arc blow" and ensures consistent weld quality across long duty cycles. The C-clamp configuration is particularly advantageous when attaching to structural steel, thick plates, or pipe, as it can be tightened securely onto irregular surfaces where spring clamps might slip or fail.

The unit features a robust cable connection point, typically accommodating large-gauge welding cables necessary for 600A service. Its rugged design withstands the mechanical abuse common in shipyards, fabrication shops, and construction sites. By providing a secure and stable ground, the WGC-600 protects sensitive welding power sources and improves the overall efficiency of the welding circuit.

Technical Benefits

• Low Resistance: High clamping pressure reduces contact resistance, preventing energy loss.


• Thermal Stability: Heavy alloy construction dissipates heat effectively during prolonged use.


• Versatile Grip: Designed to securely hold both flat surfaces and round profiles like pipe.
