  • Main materialHAWA
  • Product typeArc Flash Protection
  • 500 A capacity handles heavy welding jobs
  • 10 in overall length gives wide reach on workpieces
  • Copper body and jaws deliver strong conductivity
  • Insulated spring reduces arc-flash risk during use
  • Ball-point screw secures cable up to 4/0 AWG

500 Amp Welding Ground Clamp

This Tweco ground clamp carries a 500 ampere rating and suits heavy-duty arc welding jobs. The copper body and copper alloy connection conduct current efficiently. An insulated spring and 10 inch overall length give the operator a secure grip. A ball-point screw accepts cable up to 4/0 AWG for a solid electrical join.

Suitable Applications and Limits

The clamp fits flat plate workpieces and opens to a maximum jaw width of two inches with a throat depth of 5.25 inches. It is compatible with ESAB equipment and designed for arc flash protection. Welders who need to attach to round pipe, thick structural shapes or surfaces wider than the jaw opening should choose a different clamp style.

Deciding Specification

The 500 ampere maximum current rating is the single figure that determines whether this clamp matches the welding machine output. Exceeding this rating can cause overheating and connection failure. Verify the power source amperage before purchase.

Questions about this item

Does the 500 A ground clamp generate noticeable heat during all-day welding?

The copper body and copper-alloy connection conduct current efficiently, so heat buildup stays low even at the 500 A rating during continuous use.

What cable gauge must I already have to connect the ball-point screw on this clamp?

The clamp accepts cable up to 4/0 AWG, so you need a welding lead of that size or smaller for the ball-point screw connection.

Will the 2 in jaw opening and 5 1/4 in throat depth clear the flat-plate fixtures I keep from older jobs?

Yes, the 2 in maximum jaw opening and 5 1/4 in throat depth fit standard flat plates used with earlier Tweco or ESAB setups.
