Lincoln Electric SuperGlaze 4043 welding wire

This product is a one-pound plastic spool of Lincoln Electric SuperGlaze 4043 MIG welding wire with a 0.03 inch diameter. It is classified as AWS ER4043 and is intended for welding aluminium to aluminium. The wire is supplied new and carries California Proposition 65 warnings for cancer and reproductive harm.

Suitable for aluminium MIG work.

This spool suits welders who need ER4043 filler metal for aluminium-to-aluminium joints using a MIG process. It is not for welding steel, stainless steel, or other base materials that require a different alloy classification or wire diameter.

0.03 inch ER4043 diameter on a one-pound spool

The decisive specification is the 0.03 inch wire diameter combined with the AWS ER4043 classification on a one-pound plastic spool. Verify that your feeder and gun liner accept this diameter and that your procedure calls for ER4043 before purchasing.

Questions about this item

How do I install the SuperGlaze 4043 .030 wire on my MIG welder and what step is often missed?

Mount the 1 lb plastic spool, feed the .030 aluminium wire through the drive rolls and liner, then set the drive-roll tension light — aluminium wire deforms if the pressure is too high.

What maintenance or replacement will this ER4043 aluminium wire need later?

Replace the spool when the 1 lb of wire is consumed; keep the plastic spool sealed when not in use to prevent oxide buildup on the .030 wire surface.

What limit appears first during sustained MIG welding with this .030 ER4043 wire?

The 1 lb spool capacity limits continuous run time; frequent spool changes are required on long aluminium-to-aluminium welds.
