Alcotec ER4043 .035 16 lb Aluminium MIG Wire

SKU CH-PFV7-4MBDD

16 lb spool of ER4043 aluminium MIG wire, .035 in diameter, for DCEP welding of 4043-grade aluminium in flat, horizontal, overhead and vertical-up positions

  • TypeWelding Supplies
  • AWS ER4043 classification ensures reliable aluminium welds
  • 035 in diameter suits a wide range of MIG applications
  • 34 ksi tensile strength delivers strong joint integrity
  • 16 lb steel spool supports extended production runs
  • Qualified for flat, horizontal, overhead and vertical-up positions

ER4043 .035 Aluminium MIG Wire

This 16 lb spool of ER4043 aluminium MIG wire is intended for MIG welding of 4043 grade aluminium to aluminium. The wire diameter is .035 in and the spool is steel. The product is new and carries California Proposition 65 warnings for cancer and reproductive harm.

Suited for DCEP flat and overhead positions

This wire suits welders using DCEP current in flat, horizontal, overhead or vertical-up positions who need 34 ksi tensile strength and 28 ksi yield strength with 100 percent argon shielding. It is not for buyers who require a different AWS classification, a different wire diameter or a spool weight other than 16 lb.

AWS ER4043 classification and .035 diameter

The decisive specification is the AWS ER4043 classification combined with the .035 in wire diameter, which determines compatibility with 4043 grade aluminium and the stated mechanical properties. Verify that your application calls for this exact classification and diameter before purchasing.

Questions about this item

What size spool and wire diameter does the ER4043 .035 16 lb aluminium MIG wire use?

The wire is wound on a steel spool weighing 16 lb and has a diameter of .035 in, matching the ER4043 specification for aluminium MIG welding.

How do I set up the wire for DCEP welding with 100 percent argon shielding gas?

Install the spool on a MIG gun rated for aluminium, select DCEP polarity, flow 100 percent argon, and set the machine for the recommended wire feed speed to avoid bird-nesting.

When should the ER4043 wire spool be replaced during production welding?

Replace the 16 lb spool when the remaining wire runs low enough to cause inconsistent feed, typically after depositing roughly 16 lb of weld metal per spool.
