HALANSM® HLN-G002Y Silver Electrode for Kjellberg HiFocus130i O₂ Plasma – 25-200A

Summary Box — HALANSM® HLN-G002Y is a direct replacement silver-bonded copper cathode (OEM cross-reference G002Y / .11.848.221.300) engineered for Kjellberg HiFocus130i, HiFocus160i, HiFocus280i, HiFocus360i, and HiFocus440i plasma systems using PerCut450M torches with O₂ plasma gas. Built with a copper alloy body and silver-bonded hafnium emitter, it delivers stable arc ignition and Contour Cut / keyhole cutting capability for mild steel, stainless steel, and aluminum from 0.5mm to 80mm. G002Y replaces legacy S002Y as Kjellberg's designated electrode for the new Contour Cut (keyhole cutting) technology.

1. What Is HALANSM® HLN-G002Y?

HALANSM® HLN-G002Y is a direct replacement silver-bonded copper cathode with OEM part number G002Y (.11.848.221.300), compatible with Kjellberg HiFocus130i, HiFocus160i, HiFocus280i, HiFocus360i, and HiFocus440i plasma cutting systems operating at 25-200A with O₂ plasma gas. The electrode features a copper alloy body with a silver-bonded hafnium emitter insert, engineered to Kjellberg's dimensional tolerances for the PerCut450M torch platform. It serves as Kjellberg's designated cathode for Contour Cut (keyhole cutting) technology — the successor to legacy S002Y (.11.843.021.320), which was designed for older PerCut160 and PerCut370.1 torches.

The HLN-G002Y is water-cooled and rated for high-duty-cycle production cutting. Its silver-bonded emitter interface enhances thermal extraction from the hafnium tip, stabilizing the arc root under sustained O₂ plasma loads and extending cathode lifespan versus standard copper electrodes.

5. Application & Use Cases

✅ Ideal for

• Mild steel production cutting at 80-120A O₂ — 12mm mild steel at 1300-1400mm/min on HiFocus130i; ideal for fabrication shops, structural steel, and job shop production

• Contour Cut / keyhole cutting at 120-200A O₂ — small-hole cutting without secondary operations on HiFocus280i/360i with PerCut450M; eliminates taper and dross in holes ≤0.5× material thickness

• Robotic 3D plasma cutting — G002Y + PerCut450M is Kjellberg's designated stack for robot-mounted plasma; 0.5-25mm mild steel, stainless steel, and aluminum at speeds up to 7000mm/min

• Automotive and aerospace fabrication — ±0.1mm tolerance on 45° bevel cuts; near-zero dross on stainless and aluminum per ISO 9013 Class 1

❌ Not recommended for

• HiFocus360i / HiFocus440i at 280-440A — G002Y is rated 25-200A. For these systems at high amperage, use HLN-G032Y (280A) or HLN-G034Y (330-400A)

• Ar/H₂ stainless steel cutting (HiFinox process) — G002Y is an O₂ electrode. For Ar/H₂ plasma on stainless, use HLN-G042Y or HLN-G052Y cathodes

• PerCut160 / PerCut370.1 torches — these require legacy S002Y (.11.843.021.320), not G002Y

6. Why Choose HALANSM® HLN-G002Y

• Silver-bonded hafnium emitter — silver interface layer (429 W/m·K) enhances thermal extraction vs standard copper (401 W/m·K), slowing crater formation and extending emitter life

• OEM-equivalent dimensional accuracy — machined to Kjellberg G002Y tolerances; direct drop-in fit for PerCut450M torch with no gas parameter adjustments

• 100% inspected — every HLN-G002Y cathode undergoes dimensional and conductivity inspection before shipment; ISO 9001:2015 certified manufacturing

• Stable arc ignition — silver-bonded emitter delivers consistent high-voltage low-frequency (10kV, 100Hz) arc strike; reduces misfire rate vs generic copper electrodes

• High-volume supply — 10,000+ pcs/month production capacity; 3-5 business day lead time for in-stock orders; MOQ 5 pcs

• Cost efficiency — silver-bonded construction extends lifespan vs standard copper cathodes while maintaining competitive unit pricing for fabrication shops

7. FAQ

• Is HALANSM® HLN-G002Y compatible with Kjellberg HiFocus130i?

Yes. HALANSM® HLN-G002Y is a direct replacement for Kjellberg G002Y (.11.848.221.300), fully compatible with HiFocus130i, HiFocus160i, HiFocus280i, HiFocus360i, and HiFocus440i plasma systems using the PerCut450M torch with O₂ plasma gas. It is rated for 25-200A O₂ cutting and supports Contour Cut (keyhole cutting) technology.

• Is HLN-G002Y the same as S002Y?

No. G002Y (.11.848.221.300) is the new-generation cathode Kjellberg designed for the PerCut450M torch and Contour Cut technology. S002Y (.11.843.021.320) is the legacy cathode for PerCut160 and PerCut370.1 torches. While both serve HiFocus130i/160i/280i systems, they are NOT interchangeable — G002Y must be paired with the PerCut450M torch stack, and S002Y with the PerCut160/370.1 stack.

• What gas should I use with HLN-G002Y?

O₂ as primary plasma gas, with N₂ or Air as swirl gas. Required specifications: O₂ purity ≥ 99.5%, N₂ ≥ 99.99%. Operating pressure typically 0.8-1.0 MPa at flow rates of 1250-3600 L/h depending on amperage. Air plasma is also supported as an alternative to O₂, though cut quality and electrode lifespan are optimized with O₂.

• Can I use HLN-G002Y on HiFocus440i at 360-400A?

No. HLN-G002Y is rated 25-200A. Running it at 280-400A causes rapid hafnium erosion, double arcing, and potential torch damage. For HiFocus360i/440i at 280-400A, use HLN-G032Y (280A) or HLN-G034Y (330-400A). For Ar/H₂ stainless steel cutting on these systems, use HLN-G042Y or HLN-G052Y.

• When should I replace the HLN-G002Y electrode?

Replace when the hafnium emitter crater depth reaches 1/16 inch (1.6mm), or when crater diameter exceeds 60% of the emitter face, or when circumferential cracking appears around the emitter. Typical lifespan: 200-400 arc starts under standard fabrication conditions. Continuing to cut past this threshold risks double arcing that destroys the nozzle, swirl gas cap, and protective cap simultaneously.

• Does HLN-G002Y require adjusting my HiFocus cutting parameters?

No. HLN-G002Y is machined to Kjellberg G002Y OEM dimensional tolerances. It slots directly into the PerCut450M torch and matches original gas flow dynamics. No reprogramming of gas parameters, cutting tables, or amperage settings is required — your existing HiFocus130i/280i/360i/440i cutting programs remain valid.
