0558102344 - ESAB Crossbow Portable CNC Plasma System with A40 Cutter 575V

Technical Overview: ESAB Crossbow Plasma Kit A40 575V

The ESAB Crossbow Plasma Kit A40 575V (SKU: 0558102344) is a fully integrated, mechanized cutting solution designed to bring CNC automation to fabrication environments requiring portability and industrial power compatibility. This system pairs the versatile Crossbow gantry platform with the A-Series A40 Air Plasma power source, specifically configured for 575V three-phase electrical inputs common in heavy industrial sectors. The core of the system is its compact, lightweight aluminum beam design, which provides the rigidity necessary for precision cutting while remaining light enough for two-person portability.

Technically, the Crossbow system features a sophisticated CNC controller embedded directly into the unit. This controller drives a longitudinal rack-and-pinion system and a transverse drive, ensuring smooth contouring and accurate dimensional tolerances. A critical feature for automated plasma applications is the included Motorized Lifter with Arc Voltage Control (AVC). The AVC system continuously monitors the arc voltage to determine the torch-to-work distance, automatically adjusting the Z-axis height in real-time. This compensation is vital for maintaining cut quality across plates that may suffer from thermal distortion or uneven surfaces, thereby extending consumable life and reducing dross.

The A40 plasma power source included in this kit delivers 40 Amps of cutting current at 100% duty cycle (depending on specific environmental ratings), making it suitable for continuous production on thinner gauge materials and reliable piercing on plate up to its rated capacity. The 575V input requirement ensures stable operation on high-voltage grids, minimizing current draw and maximizing electrical efficiency. The system also includes a standard shape library within the CNC, allowing operators to program common geometries (circles, rectangles, flanges) directly at the machine interface without the need for offline CAD/CAM software, although USB connectivity is provided for importing complex nested programs.
