Spirit 400a (Auto-Gas) Plasma Cutter



The Spirit 400a plasma cutting system represents a major breakthrough in precision high current density plasma cutting and marking. Its 400 amp output provides the greatest thickness capacity and highest processing speeds in the industry while incorporating the exceptional consumable life common to all Spirit systems. This system truly offers the best of everything: quality, speed, capacity, and economy.

The Spirit 400a system is capable of cutting most metals to 2’’ (50.0mm) and has a maximum capacity of 3’’ (75.0mm)

The Spirit 400a automatically sets process parameters which equates to exceptional ease of operation. Combining convenience with the ultimate in cut quality and the highest processing speed, the Spirit 400a truly sets the standard in precision plasma cutting.

With the system’s automatic gas console (AGC), you simply select the material type and thickness or let your computer’s serial port transmit the cutting parameters. The rest is automatic, and especially easy when interfaced to a 10LCD+ or Phantom Control.

The Spirit 400a is a precision high current density plasma that delivers incomparable cut edge quality with bevels of 2° or less. The Spirit 400a system is one of four fully automated systems in the KALIBURN Spirit family. Other Spirit systems offer identical cut quality but each has a unique amperage range and corresponding thickness capacity.

The Spirit 400a is available with the optional INOVA Torch Height Control System. Also, a pneumatic safety switch can be added to protect the torch from collision damage.

The HfOT™ (Hafnium Optimizing Technology) is proprietary technology that maximizes consumable life while ensuring superior cut quality. HfOT™ begins with the design of the torch and consumables. The components are designed to provide proper arc formation, constriction, and centering. HfOT™ includes a breakthrough method for starting and stopping the plasma arc, which is where the majority of the consumable wear occurs. HfOT™ minimizes consumable wear during the start up and shut down by uniquely and precisely controlling the relationship between the arc current and plasma gas. HfOT™ results in superior cut quality, extraordinary consumable life, and low operating cost.
