  • 34 ksi tensile strength holds joints under load
  • 20 lb plastic spool reduces changeover downtime
  • Suitable for flat, horizontal, overhead and vertical-up positions

Alcotec ER4043 Aluminium MIG Wire

This aluminium MIG wire carries the AWS ER4043 classification and is spooled at a .047 inch diameter. It is intended for fabricators joining aluminium to aluminium using a DCEP welding current.

20 lb plastic spool for extended runs

The twenty pound plastic spool reduces the frequency of reloads during long production sessions. Its weight suits workshops that run continuous beads in flat, horizontal, overhead or vertical-up positions.

Standard MIG gun compatibility

The wire feeds through conventional MIG guns set for aluminium alloys, so no specialised drive rolls are mandated. Users must verify their machine delivers DCEP polarity and one hundred percent argon shielding to meet the published tensile and yield values.

Questions about this item

Will the plastic spool need to be replaced during the life of this 20 lb coil?

The wire is supplied on a plastic spool; once the 20 lb of ER4043 is consumed the spool is empty and a new spool of wire is required.

What mechanical limit appears first when welding continuously with 100 % argon?

The as-welded yield strength is 28 ksi with 100 % argon, so joint deformation at that stress level is the first mechanical limit.

How much fume and heat should I expect when running this aluminium MIG wire all day?

California Proposition 65 warnings note the wire contains chemicals known to cause cancer and reproductive harm, so fume extraction and PPE are essential during prolonged use.
