Mild Steel Flux Cored Wire - Metal Cored Wire
Metal-cored welding wire is a composite, gas-shielded wire (AWS A5.18) that combines the high deposition of a tubular wire with the near-slagless, clean finish of solid MIG wire. It delivers high travel speeds, excellent efficiency, and very low spatter under an argon / CO² blend on DC+ — a favorite for high-production and robotic structural welding. Common sizes .045" and up.

Frequently Asked Questions
How is metal-cored wire different from flux-cored?
Metal-cored wire is filled mostly with metal powder rather than flux, so it leaves almost no slag — you get the deposition rate of a tubular wire with a clean, solid-wire-like finish. It needs shielding gas and runs on DC+.
Where is metal-cored wire used?
High-production and automated/robotic structural welding, where its fast travel speeds, high efficiency, and minimal cleanup save labor.
