The 120A and 200A plasma cutter models are industrial-grade air plasma cutting systems designed for continuous operation in heavy fabrication environments. Both units utilize IGBT inverter technology with non-contact pilot arc ignition. This documentation covers technical specifications, operational characteristics, application parameters, and support procedures.

1 Non-Contact Pilot Arc Ignition
The system employs non-contact high-frequency arc starting. The pilot arc initiates without the torch contacting the workpiece surface. This enables cutting on painted, rusted, or uneven materials without preparatory scraping.
2 100% Duty Cycle at Rated Temperature
Duty cycle is rated at 100% under 40°C ambient temperature at full rated output current. The thermal overload protection system does not interrupt operation under standard continuous use conditions.
3 Wide Current Regulation Range
The 120A model provides adjustable output from 30A to 120A. The 200A model provides adjustable output from 40A to 200A. This range accommodates material thicknesses from thin gauge sheet to heavy structural plate.
4 Arc Voltage Signal Output
The system outputs arc voltage signals at selectable ratios: 1:1, 1:20, 1:50, and 1:100. Factory default is 1:1. This signal interfaces with CNC height control systems for automated torch-to-workpiece distance management.
5 Dual Cooling Configuration (200A Model Only)
The 200A model supports both air-cooled and water-cooled torch configurations. Air-cooled is standard. Water-cooled is available for extended continuous operation at maximum output.

1 Material Compatibility

2 Industry Applications

Shipbuilding: Hull plate cutting, bracket removal, stiffener trimming. The 200A model achieves 32mm quality cuts on ship steel.

Steel Structures: Beam and column fabrication, base plate cutting. Both models operate with CNC gantry integration.

Bridge Construction: On-site field cutting. Compressed air only operation eliminates mixed gas logistics.

Mining Equipment: Wear plate severance, bucket repair, chassis modification. Handheld cut capacity reaches 45mm (120A) and 65mm (200A).

Automotive Manufacturing: Prototype fabrication, chassis rail cutting, suspension bracket production.

General Fabrication: HVAC ductwork, custom signage, equipment guards, furniture frames.

• Industry: Structural steel fabrication
• Location: Southeast Asia
• Previous equipment: 80A plasma cutter, 60% duty cycle
• Issue: Thermal shutdown after 2 hours of continuous operation on 12mm plate. Production delays due to cooldown periods.
• Solution implemented: Installation of one 200A model integrated with existing CNC gantry. Arc voltage signal configured to 1:20 ratio for height controller. Operator training completed on current adjustment for varying thicknesses.
• Measured results:
• Cut time on 12mm plate: reduced from 4 min/m to 2.5 min/m
• Thermal shutdown events: eliminated
• Shift production: full 8-hour continuous operation achieved
• Subsequent order: second 200A unit purchased within 6 months

1 Selection Criteria: 120A vs. 200A Model

2 Compressed Air Requirements

Supply pressure range: 0.5–0.8 MPa
Gas type: Compressed air only (no mixed gases or nitrogen required)
Air quality recommendation: Dry air with dew point ≤ -20°C. Moisture in supply line reduces cut quality and consumable service life. Installation of an air dryer is recommended for humid environments.

3 Air-Cooled vs. Water-Cooled Torch (200A Model)

1.Packaging Specification
Container type: Fumigation-free plywood crate
Compressive strength: Meets export standards
Sealing: Leak-proof and waterproof joint construction
Customs clearance: Simplified due to fumigation-free materials

2 Delivery Timeline
7–15 days after payment confirmation, dependent on destination region.
3 Included Documentation
Mechanical test report
Factory video inspection record
User manual
Warranty certificate
CE declaration of conformity (available upon request)
