Industrial High-Capacity Cutting

The HT-4000 is a legendary 400-amp high-definition plasma system designed for heavy-duty automated cutting. As a "Master" unit, this power source can operate as a standalone 400A system or be paired with "Slave" units to reach higher amperages for extreme plate thickness.

Technical Specifications

• Output Current: 400 Amps @ 100% Duty Cycle
• Input Voltage: 240/480V, 3-Phase, 60 Hz
• Cutting Capacity: Up to 2" (Production) / 3" (Maximum) mild steel
• Gas Requirements: Oxygen (O2), Nitrogen (N2), Air
• Dimensions: 48" D x 34" W x 51" H
• Weight: Approximately 1,600 lbs

Key Features for Buyers

• Master Control Logic: Unlike "Slave" units, this unit (S/N 131) features the full internal control boards necessary to interface with a CNC table and Remote High Frequency (RHF) console.
• Reliable Transformer Tech: Built with heavy-duty copper windings, these transformer-style units are famously durable and often preferred over newer inverters for their ease of repair in harsh environments.
• Serviceability: Because the HT-4000 was an industry standard for decades, parts and consumables remain widely available from both OEM and aftermarket suppliers.
