HALANSM® HLN-G032Y Silver Electrode for Kjellberg HiFocus360i/440i – 280A O₂

Summary Box — HALANSM® HLN-G032Y is a direct replacement silver-bonded copper cathode (OEM cross-reference G032Y / .11.848.421.310) engineered for Kjellberg HiFocus360i and HiFocus440i plasma systems using PerCut450M torches with O₂ plasma gas. Built with a copper alloy body and silver-bonded hafnium emitter, it is rated for 280A O₂ cutting — the designated high-amperage cathode in Kjellberg's PerCut450M "G" type consumable stack for thick mild steel, stainless steel, and aluminum production cutting from 12mm to 80mm.

1. What Is HALANSM® HLN-G032Y?

HALANSM® HLN-G032Y is a direct replacement silver-bonded copper cathode with OEM part number G032Y (.11.848.421.310), compatible with Kjellberg HiFocus360i and HiFocus440i plasma cutting systems operating at 280-400A 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 the designated high-amperage cathode (rated 280A) in Kjellberg's PerCut450M "G" type stack, positioned above G002Y (20-200A) and alongside G034Y (330-400A) in the O₂ cathode family .

The HLN-G032Y is water-cooled and built for 100% duty cycle production cutting. Its silver-bonded emitter interface enhances thermal extraction from the hafnium tip at sustained 280-360A loads, stabilizing the arc root and extending cathode lifespan versus standard copper cathodes under heavy production conditions.

⚠️ Amperage boundary: G032Y is rated 280A. For sustained 330-400A cutting on HiFocus440i, step up to G034Y. For 20-200A work on smaller HiFocus units, use G002Y. Running G032Y below 200A or above 320A reduces emitter life and risks double arcing.

5. Application & Use Cases

✅ Ideal for

• Thick mild steel production cutting at 280A O₂ — 25mm mild steel at 600-800mm/min on HiFocus360i; ideal for structural steel fabrication, shipbuilding, and heavy plate job shops

• Heavy-duty 360A O₂ cutting on HiFocus440i — 40mm mild steel at 400-500mm/min; maximum productivity for dense production schedules requiring 100% duty cycle

• Stainless steel and aluminum medium-thickness cutting — 12-25mm stainless and aluminum at 280-360A O₂; automotive die fabrication, chemical tank manufacturing, and architectural metalwork

❌ Not recommended for

• HiFocus130i/160i at 20-200A — G032Y is rated 280A minimum. For these systems, use HLN-G002Y (20-200A) to avoid arc instability and rapid emitter erosion

• Ar/H₂ stainless steel cutting (HiFinox process) — G032Y is an O₂ cathode. For HiFinox on HiFocus360i/440i, use HLN-G052Y Ar/H₂ cathode instead

• Sustained 400A operation — G032Y is rated 280A. For continuous 400A cutting, step up to HLN-G034Y (330-400A) for optimal emitter life

6. Why Choose HALANSM® HLN-G032Y

• Silver-bonded hafnium emitter — copper alloy body with silver interface layer delivers enhanced thermal extraction at sustained 280-360A loads, slowing hafnium crater formation versus standard copper cathodes

• OEM-equivalent dimensional accuracy — machined to Kjellberg G032Y (.11.848.421.310) tolerances for direct drop-in fit in PerCut450M torch; no gas parameter adjustments required

• 100% dimensional inspection — every HLN-G032Y cathode is inspected for concentricity, emitter seating depth, and conductivity before shipment; ISO 9001:2015 certified manufacturing

• Stable high-amperage arc ignition — engineered for Kjellberg's high-voltage low-frequency (10kV, 100Hz) pilot arc system, ensuring consistent ignition at 280-360A

• Production-grade supply — high-volume manufacturing capacity; 5-10 business day lead time for in-stock orders; MOQ 5 pcs

• Cost-efficient for thick plate — silver-bonded construction extends cathode life under sustained high-amperage O₂ cutting, reducing cost-per-cut in heavy fabrication

7. FAQ

• Is HALANSM® HLN-G032Y compatible with Kjellberg HiFocus440i?

Yes. HALANSM® HLN-G032Y is a direct replacement for Kjellberg G032Y (.11.848.421.310), fully compatible with HiFocus360i and HiFocus440i plasma systems using the PerCut450M "G" type torch with O₂ plasma gas . It is rated for 280A O₂ cutting and integrates into the complete PerCut450M stack: G931Y cooling tube → G4350 swirl gas cap → G3219 nozzle cap → G23XXY nozzle → G121 gas guide → G032Y electrode → G521 protective cap.

• Is G032Y the same as G002Y?

No. G032Y (.11.848.421.310) is the high-amperage O₂ cathode rated 280A, designed for HiFocus360i/440i with PerCut450M . G002Y (.11.848.221.300) is the standard O₂ cathode rated 20-200A, designed for HiFocus130i/160i/280i . They are not interchangeable — G032Y requires the 280-400A cooling tube (G931Y) and matching high-amperage nozzle (G2326Y/G2330Y), while G002Y uses the 20-200A cooling tube (G901Y) and lower-amperage nozzles (G2006Y–G2016Y).

• What gas should I use with HLN-G032Y?

O₂ as primary plasma gas, with O₂, N₂, or Air as swirl gas . Required O₂ purity ≥ 99.5%. Operating pressure typically 0.8-1.0 MPa at flow rates of 2500-3600 L/h at 280-360A. For stainless steel cutting with Ar/H₂ (HiFinox process), do not use G032Y — switch to HLN-G052Y Ar/H₂ cathode . F5 gas is also supported as an alternative plasma gas on HiFocus systems .

• Can I use HLN-G032Y on HiFocus130i?

No. HLN-G032Y is rated 280A minimum. HiFocus130i operates at 20-130A — installing a 280A-rated cathode in a low-amperage system causes arc instability, incomplete hafnium emitter activation, and premature failure. For HiFocus130i, use HLN-G002Y (20-200A O₂ cathode) .

• When should I replace the HLN-G032Y 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: 150-300 arc starts under sustained 280-360A production cutting, depending on material thickness and gas quality. Continuing to cut past this threshold risks double arcing that destroys the nozzle, swirl gas cap, and protective cap simultaneously.

• Does HLN-G032Y require adjusting my HiFocus360i/440i cutting parameters?

No. HLN-G032Y is machined to Kjellberg G032Y OEM dimensional tolerances . It slots directly into the PerCut450M torch and matches original gas flow dynamics. Your existing HiFocus360i/440i O₂ cutting programs and gas parameter tables remain valid — no reprogramming required.
