3-1330-2 - Cutmaster 102 Plasma Cutter Power Source 460V

Industrial-Grade Plasma Power Source

The Thermal Dynamics Cutmaster 102 Power Supply (SKU: 3-1330-2) represents a pinnacle in air plasma cutting technology for industrial environments requiring 460V 3-phase input. Designed to deliver a substantial 100 Amps of cutting current, this unit is engineered for fabrication shops, heavy construction, and manufacturing facilities where reliability and duty cycle are paramount. The power supply itself weighs approximately 62 lbs (28.1 kg), making it one of the most power-dense units in its class, offering a high output-to-weight ratio that facilitates portability without sacrificing performance.

Technically, the Cutmaster 102 is rated for a recommended cut capacity of 1 inch (25 mm) and a maximum severance capacity of 1-3/4 inches (45 mm). The duty cycle is rated at 60% at 100 Amps, allowing for sustained operation during long cuts on thick plate. At reduced amperages, the duty cycle increases significantly, reaching 100% at approximately 70-80 Amps. The unit utilizes a microprocessor-controlled front panel with LED indicators that provide immediate feedback on AC power status, gas pressure parameters, and internal temperature, ensuring the operator can diagnose system readiness at a glance.

The chassis is protected by the proprietary True Guard roll bar, a tubular steel cage that surrounds the power supply. This feature not only protects the internal components and casing from impact damage common in harsh industrial environments but also serves as multiple grab points for easy lifting and positioning. The 3-1330-2 configuration is the power supply only, allowing users to integrate it with existing torch assemblies or customize their setup with specific lead lengths. It is designed to pair seamlessly with the SL100 1Torch, which features the ATC (Advanced Torch Connector) quick disconnect system, enabling rapid changeovers between hand and mechanized torches.

Gas management is handled internally with an automatic air regulation system that requires a supply of clean, dry, oil-free air or nitrogen. The system typically operates between 70 and 85 PSI (4.8 - 5.9 bar) with a flow rate requirement of approximately 6.7 CFM (190 lpm). The Auto-Pilot Restart feature is a critical technical addition, allowing the pilot arc to instantly re-fire when cutting across gaps in expanded metal or grating, eliminating the need for manual re-triggering and reducing operator fatigue.
