10481250 - Tweco ELC410M Eliminator Compact 400A MIG Gun for Miller

Technical Overview: Tweco ELC410M3545 MIG Gun

The Tweco ELC410M3545 is a premium air-cooled MIG gun from the renowned Eliminator Compact series, designed to deliver 400 Amps of welding power at a 60% duty cycle (using CO2 gas). This model is specifically configured with a direct Miller-style rear connection, ensuring immediate compatibility with a wide range of Miller wire feeders and integrated MIG machines. The "ELC" prefix denotes the Eliminator Compact line, which features a handle geometry that is approximately 30% smaller than standard No. 4 guns, providing superior ergonomics for precision welding and reduced operator fatigue.

Optimized for Performance and Durability

This assembly features a 10-foot (3-meter) cable, which is ideal for stationary welding stations and production environments where a longer cable is unnecessary and potentially detrimental to wire feed smoothness. The cable construction utilizes high-quality copper stranding for efficient current transfer and is protected by a heavy-duty rubber jacket resistant to industrial contaminants, sparks, and abrasion. The gun is factory-fitted with a liner and contact tip setup for 0.035" (0.9mm) to 0.045" (1.2mm) welding wires, making it ready for immediate deployment in medium-to-heavy fabrication applications.

Superior Consumable System

The ELC410M3545 utilizes the proprietary Tweco Eliminator front-end consumables. This system is favored in the industry for its simplicity and performance. The contact tips feature a large surface area for electrical transfer, reducing heat buildup and extending tip life. The gas diffuser and nozzle design ensure laminar gas flow, minimizing porosity and weld defects. The conductor tube (gooseneck) is insulated and rotatable, allowing the welder to position the trigger and nozzle angle to suit the specific joint configuration, which is critical for out-of-position welding.

Key Applications

This gun is engineered for high-amperage applications such as structural steel fabrication, heavy equipment manufacturing, and general industrial maintenance. The combination of the compact handle, robust 400A rating, and reliable Miller connection makes it a versatile tool for shops that require both power and precision. The trigger mechanism is designed for longevity, capable of withstanding hundreds of thousands of cycles, ensuring that the tool remains reliable shift after shift.
