Product Description
The FORNEY INDUSTRIES INC 42294 is an ER5356 aluminum MIG welding wire designed for gas metal arc welding (GMAW) applications on aluminum base metals. Spooled at 0.035 inches in diameter and packaged in a 1-pound spool, this wire delivers consistent feedability and a stable arc for aluminum fabrication and repair work. The ER5356 classification indicates a 5xxx-series aluminum alloy wire, which provides good corrosion resistance and strong mechanical properties in the finished weld. It is the appropriate choice when the base metal composition calls for a 5000-series filler alloy.
This wire is used in residential, commercial, and light industrial welding scenarios where aluminum components require joining or repair. Typical applications include aluminum boat hull repairs, automotive fabrication, structural aluminum frames, and general sheet metal work. It is suited for use with a MIG welder equipped with a spool gun or push-pull gun to handle the softer aluminum wire without bird-nesting in standard steel drive systems.
Key Features
- ER5356 classification 5xxx-series aluminum alloy filler wire with good corrosion resistance
- 0.035 inch diameter for use with compatible MIG welding equipment
- 1-pound spool suitable for smaller jobs and intermittent production runs
- Designed for gas metal arc welding (GMAW) of aluminum base metals
- Available in a 6-count package quantity for shop stocking
Compatibility
Designed as an OEM-style replacement consumable for MIG welders configured for aluminum wire, typically requiring a spool gun or push-pull gun setup and a compatible shielding gas such as argon.
Installation Notes
Installation of this wire is performed by welders and fabricators familiar with aluminum GMAW procedures. Before loading the spool, power down the welding machine and release drive roll tension to avoid deforming the soft aluminum wire. Use drive rolls rated for aluminum wire, and verify the contact tip size matches the 0.035 inch wire diameter. Consult applicable AWS D1.2 structural welding codes for aluminum when the application requires code compliance.
