ER4043 .030 Aluminium MIG Wire

This 1 lb spool of Alcotec ER4043 wire is made for MIG welding aluminium to aluminium. The .030 inch diameter suits DCEP current and works in flat, horizontal, vertical-up and overhead positions. It delivers 34 ksi tensile strength and 28 ksi yield strength with 100 percent argon shielding.

Who should choose this spool

Welders joining 4043 grade aluminium who need a small spool for portable jobs or occasional repairs. The 1 lb weight limits continuous run time, so high-volume production users should look at larger spools. Buyers needing a different alloy or wire diameter cannot use this product.

AWS ER4043 classification and .030 diameter

The AWS ER4043 classification confirms the alloy chemistry for aluminium-to-aluminium welds. The .030 inch wire diameter sets the feed rate and current range for the listed welding positions. Match these two specifications to your welder settings and base material before purchase.
