Description
Unleash Oxygen Cutting Performance: Advantages of the Kjellberg .11.828.203.414 1.4mm Lee Plasma Nozzle
For industrial fabricators tackling thick-section carbon steel with oxygen plasma, the Kjellberg Lee Plasma Nozzle (.11.828.203.414) redefines cutting efficiency. Engineered for HiFocus® 100-150A systems, this 1.4mm orifice German consumable delivers unparalleled precision and longevity. Below are its transformative advantages:
⚡ 1. Oxygen-Cutting Optimization
→ Patented Gas Dynamics
-
High-Velocity Tapered Orifice: Accelerates oxygen flow by 40% vs. standard nozzles, boosting oxidation reaction for:
-
1.8x faster cutting on 25mm carbon steel (3,800 mm/min vs. 2,100 mm/min industry avg)
-
Near-zero hard slag: Top-edge dross ≤0.2mm (meets ISO 9013 Class 1)
-
-
Vortex Stabilization: Concentric gas swirl maintains arc focus at 150A, preventing kerf widening (>±0.1mm tolerance held on 35mm plate)
→ Material Science Breakthrough
-
CuAgZr Alloy Base: Lee Plasma Nozzle 385 W/m·K thermal conductivity (25% > copper)
-
NanoCeramic Shield Coating: Resists 18,500°C piercing temperatures
-
Anti-Spatter Geometry: 70% less metal adhesion vs. conventional designs
🔥 2. Performance Specifications

| A572-50 | 35mm | 2,200 mm/min | 90.0°±0.2° | 0.30mm |
| Hardox 450 | 25mm | 3,100 mm/min | 89.8°±0.4° | 0.28mm |
⏳ 3. Extended Lifespan & ROI
→ Durability Advantages
-
3.0–3.5 hours runtime at 130A (validated Kjellberg Test PL-2305)
-
200+ pierces on 30mm steel without orifice deformation
→ Cost-Per-Cut Savings
| Metric | Lee Nozzle 1.4mm | Generic Nozzle | Annual Savings |
|---|---|---|---|
| Cost/Hour | €4.20 | €14.30 | €8,100 |
| Cut Speed Gain | +45% | Baseline | €5,200 |
| Grinding Time | 0 min/hour | 22 min/hour | €6,800 |
| *(Calculations: 300 starts/day, 150A oxygen cutting, 260 days)* |
⛓️ 4. System Integration
→ HiFocus® Torch Synergy
-
Perfect Pairing: Requires Kjellberg Electrode .11.828.001.3001
-
Auto-Alignment: ≤0.015mm radial deviation prevents double-arcing
-
Thermal Lock: Lee Plasma Nozzle Direct cooling interface reduces nozzle temp by 95°C
→ Automation Excellence
-
Robotic Certification: Withstands 6G vibration (ISO 9409-1)
-
IoT Compatibility: CondiTec™ monitors orifice wear in real-time
🛠️ 5. Operation & Maintenance
→ Optimal Parameters
| Setting | Value |
|---|---|
| Oxygen Pressure | 7.0–8.5 bar (DIN EN ISO 14175) |
| Cut Height | 1.8–2.2mm |
| Max Amperage | 150A (sustained) |
→ Critical Consumable Pairings
| Component | Part Number | Function |
|---|---|---|
| Electrode | .11.828.001.3001 | Ensures arc stability |
| Shield Cap | .11.828.203.416 | Spatter protection |
| Retaining Cup | .11.830.301.151 | Precision positioning |
→ Replacement Triggers
-
Kerf width >1.55mm (original: 1.4mm)
-
Top edge rounding >0.5mm
-
Oxygen consumption increase >12%
🏭 6. Industrial Applications
-
Heavy Machinery: 35mm AR400 wear plate cutting (HAZ <0.3mm)
-
Bridge Construction: 30mm S460ML bevels at ±0.25° tolerance
-
Mining Equipment: 40mm Bisalloy 400 cuts with Ra 5.0μm finish
