Luvata A-Trode® is the universal cap electrode for reliable resistance welding of light-to-medium gauge coated and uncoated steels.

Produced with our proprietary billet casting process, the A-Trode's freedom from oxygen allows us to alloy the copper with the optimum levels of chrome and zirconium to deliver consistent welding results.

The A-Trode is available in all industry sizes, geometries and tapers or cold headed or machined to deliver your custom-made shape.
