K52010-3505 - Lincoln ST450 Fume Extraction MIG Gun Package, 450A, 5m Cable

Protect Your Health with the Lincoln ST450 Fume Extraction System

The Lincoln Electric ST450 35 X 5 Standard System One Pak (K52010-3505) is a premium fume extraction MIG gun designed to tackle the toughest industrial welding environments while prioritizing operator safety. As air quality regulations become stricter, source capture remains the most effective method for removing welding fumes. The ST450 integrates a high-efficiency vacuum channel directly into the gun nozzle, capturing up to 95% of fumes at the source before they reach the welder's breathing zone.

This "One Pak" system is a complete solution that includes the heavy-duty ST450 gun equipped with a generous 5-meter (approx. 16.4 ft) cable, giving welders the freedom to move around large assemblies without restriction. Rated for 450 Amps, this gun is built to handle high-deposition MIG and Flux-Cored welding processes commonly found in structural steel, shipbuilding, and heavy equipment manufacturing. Despite its robust extraction capabilities, the gun features an ergonomic handle design that minimizes wrist strain and maintains a comfortable grip for all-day use.

The system is compatible with most high-vacuum extraction units and is engineered to maintain shielding gas coverage even while suction is active, ensuring weld quality is never compromised. Whether you are welding mild steel, stainless, or aluminum, the ST450 provides the perfect balance of performance, durability, and safety compliance.
