  • MaterialHAWA
  • TypeArc Flash Protection
  • Reliable grounding for heavy welding with 300 A capacity
  • Arc flash protection built into the clamp design
  • Secure cable attachment via ball-point screw connection
  • Insulated spring handle reduces heat transfer to the operator

Ground clamp for 300 A welding

This Tweco ground clamp handles up to 300 A for arc welding tasks. A copper body and brass connection conduct current efficiently. An insulated spring and steel handle provide a secure grip on flat plates. The ball-point screw accepts welding cables quickly.

Suited for high-amperage flat-plate work

Welders needing a reliable ground on flat surfaces up to the rated current will find this clamp effective. The 2 in jaw opening fits thick plates and the 1 3/4 in throat depth clears workpiece edges. Buyers who require a ground clamp for pipe, angle iron or other non-flat profiles should look at a different style.

300 A maximum current rating

The 300 A limit is the single figure that determines whether this clamp matches the welding machine and application. Exceeding it risks overheating and poor arc stability. Verify the power source output before fitting this ground clamp.

Questions about this item

Which current rating should I choose for the Tweco 358-9205-1230 ground clamp?

This model is rated for a maximum current of 300 A, so select it when your welding machine operates at or below that amperage.

What does the 300 A rating mean when the clamp is on a workpiece?

It indicates the clamp can continuously carry up to 300 amperes through its copper body and brass connection without overheating during arc welding.

How does the ball-point screw connection affect the cable attachment?

The ball-point screw secures the welding cable directly to the clamp body, providing a firm mechanical and electrical joint for arc welding circuits.
