BQ3010AE4FSC - 350A Aluminum MIG Gun for Lincoln LN-25 PRO - 10ft

Technical Overview of the CM 350A Aluminum MIG Gun

The CM Industries 350A MIG Gun (SKU: BQ3010AE4FSC) is a high-performance air-cooled welding torch designed specifically for heavy-duty industrial applications involving aluminum fabrication. Rated at 350 Amperes with a 60% duty cycle using mixed shielding gases, this gun provides the thermal capacity required for sustained welding on thick aluminum sections often found in shipbuilding, trailer manufacturing, and structural repair.

This assembly features a 10-foot (3-meter) cable assembly. The shorter cable length is a critical technical specification for push-only aluminum systems, as it significantly reduces the column strength requirements of the wire, thereby minimizing the risk of buckling or "birdnesting" inside the liner. The gun comes pre-equipped with a low-friction polymer/Teflon liner, which is essential for feeding soft aluminum grades like 4043 and 5356 without shaving the wire surface or causing feed interruptions.

The backend connection is engineered to mate directly with Lincoln Electric LN-25 PRO wire feeders, a standard in portable industrial welding. The connection ensures positive electrical conductivity and secure gas sealing. The gun utilizes industry-standard front-end consumables, allowing for easy integration into existing inventory systems without the need for proprietary contact tips or nozzles. The rugged construction includes reinforced strain reliefs and an impact-resistant handle, ensuring longevity in harsh MRO environments.
