Kaliburn Spirit 275a
  • Overview
  • Specifications

The Spirit275a by KALIBURN is a full function 275 amp high current density plasma cutting and marking system incorporating fully automated process control, cutting of most metals up to 1 ¼’’ (32.0mm) thick, and has a maximum capacity of 2 ½’’ (65.0mm). It is designed to be the ultimate process tool when precise, square, and virtually dross-free cuts and ease of operation are important. Unparalleled consumable life is a benefit of all KALIBURN Spirit systems. 

The “a” is for automatic…

Automatic setting of process parameters equates to exceptional ease of operation. The KALIBURN Spirit275a combines convenience with the ultimate in cut quality. The KALIBURN Spirit275a truly sets the standard in precision plasma cutting within its thickness range. 

With the KALIBURN Spirit275a 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 Burny 10LCD+ or  Control.

The KALIBURN Spirit275a provides precision high current density plasma cut edge quality. It delivers virtually dross-free cuts with 2° or less cut edge bevel. The Spirit275a system is one of four fully automated systems in the KALIBURN family. Other Spirit systems offer identical cut quality but each has a unique amperage range and corresponding thickness capability.

The KALIBURN Spirit275a 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 KALIBURN 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.
