Plasma Cutting - Anywhere, Anytime. The Tomahawk 45 plasma cutting system is versatile and portable, weighing only 28 lbs. You can easily carry it to any job site and start cutting projects. This system can handle everything, whether cutting through thick metal or working with expanded metal. With its 45A capability, you can tackle even the most challenging cutting tasks. Tomahawk initiates the plasma arc with a simple yet reliable touch-start mechanism that eliminates many failure problems associated with high-frequency start systems. The control system includes a Parts-in-Place™ feature to ensure consumables are in place before initiating the cutting or gouging process. Hook up the compressed air, grab the torch, and you’re all set.
