UltraFlex Heavy-Duty Ground / Work Cable. 500 amp High-Performance Ground Cable 20' (7.6m) Long. 

The 500 Amp Welding Machine Ground Lead gives high-output welding setups a heavy-duty machine-side cable while keeping your ground clamp easy to change. Pair the 20' lead with an Arc-Zone Shorty™ 5' ground whip and choose the clamp style that works best for the job.

Built with heavy-duty 1/0 welding cable, an LC-40 male machine connector, and an LC-40 female connection for Shorty™ ground whips, this modular system lets you change from flat jaw to croc jaw, magnetic, C-clamp, or table grounding without replacing your full-length work lead.

Why Welders Choose the Shorty™ Ground System

• Change Clamps Fast: Swap the 5' Shorty™ whip instead of changing the entire machine ground lead.
• One Lead, Multiple Clamp Options: Build your setup around the clamp style each job requires.
• Built for Up to 500 Amps: Heavy-duty 1/0 welding cable is made for higher-output welding applications.
• Flexible Shop Setup: Switch between clamps for plate, tubing, welding tables, fixtures, repair work, and production jobs.
• Easy LC-40 Connection: The female LC-40 connection is designed for Arc-Zone Shorty™ ground whip leads.

Frequently Asked Questions

Does this ground lead include a clamp?
No. This product is the 20' machine-side lead. The Shorty™ ground whip and clamp are selected separately.

How does the Shorty™ system work?
Keep the main machine lead connected and swap the 5' clamp-side whip at the LC-40 connection whenever you need a different ground style.

Which Shorty™ clamp should I use for the full 500 Amp capacity?
Choose a Shorty™ ground cable and clamp rated for 500 amps.

Can I connect a 200 or 300 Amp Shorty™ clamp?
Yes, provided it uses the compatible LC-40 connector. The lower-rated clamp becomes the maximum amperage for that complete setup.

Can I use a 500 Amp clamp for lower-amperage welding?
Yes. A higher-rated clamp can be used below its maximum rating.
