M1339 - Miller M1339 Head Tube 45-Degree 4-Inch for Aluma-Pro/Push-Pull

Genuine Miller M1339 Head Tube for Aluma-Pro and Push-Pull Systems

The Miller M1339 Head Tube Brazed Assembly is a critical replacement component designed specifically for Miller's line of air-cooled Aluma-Pro and Push-Pull MIG guns. Engineered to meet the rigorous demands of industrial aluminum welding and fabrication, this head tube features a 45-degree bend and a 4-inch length. This specific geometry is ideal for welders who require a balance between reach and control, allowing for comfortable access to standard weld joints while maintaining a compact form factor that is easy to manipulate in tighter spaces.

Constructed as a brazed assembly, the M1339 offers superior structural integrity and electrical conductivity compared to standard mechanical connections. The brazing process ensures that the tube can withstand high amperage loads and the thermal cycling inherent in heavy-duty welding applications without loosening or losing continuity. This is particularly important in push-pull systems where consistent current transfer is vital for smooth wire feeding and arc stability, especially when welding soft aluminum wires that are prone to burn-back if contact is interrupted.

Replacing a worn or damaged head tube is essential for maintaining the quality of your welds. A damaged tube can lead to poor gas coverage, erratic wire feeding, and increased spatter. By installing the genuine Miller M1339, you ensure that your equipment operates at peak efficiency. The tube is designed to be rotatable on compatible gun bodies, allowing the operator to adjust the angle of the neck relative to the handle for maximum ergonomic comfort and visibility. This part is compatible with specific air-cooled (A) models of the Aluma-Pro and Push-Pull series, making it a versatile stock item for shops utilizing these advanced wire feeding systems.

Trust in Miller OEM parts to provide the durability and fitment required for professional results. Whether you are fabricating trailers, repairing aluminum structures, or working in general manufacturing, the M1339 Head Tube provides the reliability you expect from Miller Electric.
