Miller 231402 Work Lead Assembly, 15ft, 1/0 Cable, 300A, Dinse Connector

Reliable Grounding for Superior Welds

Every welder knows that a good weld starts with a good ground. If your work lead is frayed, cut, or overheating, your arc stability suffers, leading to spatter, porosity, and frustration. The Miller 231402 Work Lead Assembly is the genuine replacement you need to restore your machine's performance. Designed as the standard equipment for high-performance machines like the Millermatic 255 and Multimatic 255, this lead is built to handle the heat and keep you welding.

Built for the Shop Environment
At 15 feet long, this lead gives you plenty of room to move around your fixture table or large workpieces without constantly dragging the welder behind you. The 1/0 AWG cable is thick enough to carry 300 amps of power efficiently but remains flexible enough to coil up easily at the end of the day. The tough rubber jacket stands up to the daily abuse of a metalworking shop, protecting the copper strands inside from cuts and burns.

Secure Connections
The assembly comes ready to weld right out of the box. On the machine side, the large Dinse-style connector allows for a quick, quarter-turn attachment that locks solid—no tools required. On the business end, the heavy-duty ground clamp features a strong spring and wide jaw opening, ensuring it stays put on your workpiece. A solid connection at the clamp means less resistance, a smoother arc, and better penetration. Don't let a bad ground hold you back; upgrade to a fresh Miller work lead and feel the difference in your arc control.
