10201131 - Tweco Classic No. 2 MIG Gun, 200A, 10ft, Miller Connection, .045 Wire

Industry-Standard 200A MIG Welding Gun

The Tweco Classic No. 2 MIG Gun (SKU: 10201131) represents the benchmark for semi-automatic air-cooled MIG welding. For decades, the "Number 2" has been the preferred choice for industrial fabrication, maintenance, and repair operations requiring a reliable 200-amp torch. This specific configuration is engineered with a direct Miller-style backend connection, allowing for immediate plug-and-play compatibility with a wide range of Miller wire feeders and power sources. The unit comes equipped with a 10-foot cable assembly, which provides ample reach for bench-top welding and production cells where excessive cable length would otherwise create clutter or tripping hazards.

Technically, the Classic No. 2 is rated for 200 Amps at a 60% duty cycle when using CO2 shielding gas, making it a robust tool for continuous welding applications. The gun is pre-configured with a liner and contact tip setup for .045-inch (1.2mm) wire, a common diameter for structural steel and medium-to-heavy fabrication tasks. The cable construction features high-quality copper stranding to ensure efficient current transfer and minimal heat buildup, housed within a durable, abrasion-resistant outer jacket that protects against sparks, spatter, and shop floor wear.

From a maintenance and operations perspective, the Tweco Classic series offers significant advantages. It utilizes the widely available 14 Series contact tips, 22 Series gas nozzles, and 32/52 Series gas diffusers. This standardization simplifies inventory management for MRO departments, as these consumables are compatible across multiple gun amperages and are stocked by virtually every welding supplier. The mechanical trigger design is simple and field-repairable, reducing downtime. The metal-jacketed conductor tube (gooseneck) is robust and can be rotated to suit different welding positions, further enhancing the versatility of this essential welding component. This gun is an ideal replacement or upgrade for existing equipment, ensuring consistent arc performance and operator familiarity.
