0449150902 - ESAB A2 Automated Wire Feed Motor Assembly 2WD 68RPM

Precision Wire Feeding for Automation

The ESAB A2 GMAW Feed Unit (SKU: 0449150902) is a critical component designed for the A2 series of automated welding systems. Engineered to meet the rigorous demands of industrial automation, this feed unit facilitates the Gas Metal Arc Welding (GMAW) process with high reliability and precision. The unit features a 2-wheel drive (2WD) mechanism, which provides adequate traction for feeding solid wires typically used in automated MIG/MAG applications.

At the core of this assembly is a motor and gearbox combination tuned to 68 RPM. This specific gear ratio is selected to provide the optimal torque and speed range for specific welding procedures, ensuring that the wire feed speed (WFS) remains constant even under varying load conditions. Stability in wire feeding is paramount in automation, where deviations can lead to weld defects such as burn-back or stubbing. The A2 Feed Unit is built to integrate seamlessly with ESAB's modular A2 welding heads, often found on beam welding gantries, column and booms, and tractor units.

The modular design of the A2 system allows for straightforward replacement and maintenance. This unit serves as a direct replacement or upgrade for existing A2 setups requiring the 68 RPM specification. Its robust housing protects internal components from the dust, heat, and electrical noise common in heavy fabrication environments. By utilizing genuine ESAB components, operators ensure compatibility with the process controller and power source, maintaining the calibrated performance of the entire welding system.

Whether utilized in shipbuilding, pipe welding, or structural steel fabrication, the ESAB A2 GMAW Feed Unit delivers the consistent performance necessary for high-quality automated welds. It supports the continuous operation cycles typical of automated manufacturing, reducing the need for manual intervention and adjustment.
