BK12849-5 - Lincoln Electric 60A Nozzle for LC100M/LC105M Torches (5-Pack)

Technical Specification: Lincoln Electric BK12849-5 60A Nozzle

The Lincoln Electric BK12849-5 is a high-performance plasma cutting nozzle designed specifically for the LC100M (Machine) and LC105M (Machine) plasma torches. These torches are the standard cutting instruments paired with the Lincoln Electric FlexCut® 80 plasma cutting system. As a critical component in the plasma torch consumable stack, the nozzle is responsible for constricting the plasma arc, thereby increasing the energy density and velocity of the plasma gas stream. This 60 Amp variant is engineered to provide optimal cutting characteristics for intermediate gauge materials, balancing cutting speed with edge precision.

Manufactured to Lincoln Electric's exacting engineering standards, the BK12849-5 ensures precise concentricity of the orifice. This geometric precision is vital for maintaining a straight, non-beveled cut profile and stabilizing the arc during operation. The nozzle is constructed from high-grade copper alloys that facilitate efficient heat dissipation, preventing overheating and extending the service life of the consumable. It is fully compatible with cutting processes involving mild steel, stainless steel, and aluminum, making it a versatile component for diverse industrial fabrication environments.

Proper maintenance of the plasma torch requires regular inspection of the nozzle orifice. A worn or ovalized orifice can lead to arc wandering, excessive dross formation, and poor cut angularity. The BK12849-5 is supplied in a pack of five, allowing operators to maintain a ready stock of replacement parts to minimize machine downtime. When replacing the nozzle, it is also recommended to inspect the electrode and swirl ring, as the performance of the nozzle is directly influenced by the condition of the upstream consumables. This product is an OEM (Original Equipment Manufacturer) part, ensuring seamless fit and function with the FlexCut 80 system's gas flow dynamics and arc initiation protocols.

By utilizing genuine Lincoln Electric consumables like the BK12849-5, users ensure that their equipment operates within the manufacturer's specified parameters for duty cycle and cut capacity. This nozzle is specifically rated for 60A output; using it at incorrect amperage settings or with incompatible torches may result in premature failure or damage to the torch head. For industrial MRO applications, this 5-pack configuration provides a logical balance between inventory management and operational readiness.
