K5458-1 - Lincoln Tomahawk 45 Plasma Cutter System with 20ft Hand Torch

Precision Plasma Cutting Technology

The Lincoln Electric Tomahawk 45 Plasma Cutter (K5458-1) represents a significant advancement in handheld plasma cutting technology, engineered for professionals who demand precision, reliability, and safety. Operating on standard 208/230V single-phase power, this inverter-based system delivers a robust 45 amps of cutting power, capable of severing mild steel up to 3/4 inch thick while maintaining a recommended clean cut of 1/2 inch at 20 inches per minute. The unit is designed with the industrial operator in mind, featuring a 2.8-inch color LCD screen that provides a clear, user-friendly interface for monitoring settings and adjusting the continuous output control to match specific material thicknesses.

A standout technical feature of the Tomahawk 45 is its Touch Start system. Unlike traditional plasma cutters that rely on high-frequency (HF) start mechanisms—which can interfere with sensitive nearby electronics like CNC tables or telecommunications equipment—the Tomahawk utilizes a reliable mechanical electrode-to-nozzle contact method to initiate the arc. This ensures consistent ignition without the risks associated with HF. Furthermore, the Rapid Arc Restrike capability is specifically optimized for cutting interrupted surfaces, such as expanded metal or grates, by re-igniting the arc instantly as it passes over gaps, maintaining productivity without manual re-triggering.

Operational safety and longevity are core to the Tomahawk 45's design. The proprietary Parts-in-Place system actively detects the correct installation of the torch and consumables, preventing the machine from powering up if components are missing or improperly seated. This protects both the operator and the equipment. Additionally, the system's efficient cooling design and optimized electrode/nozzle geometry significantly extend consumable life, reducing long-term operating costs. The front panel purge control allows operators to set air flow rates (80-110 PSI required) without initiating the plasma arc, ensuring optimal gas pressure before the cut begins.
