HLN-G2012Y Nozzle for Kjellberg HiFocus130i/160i/280i – 130A

OEM G2012Y / .11.848.221.412 — CoolFlow™ Copper Alloy Nozzle, PerCut210M/450M "G" Type

What Is HALANSM® HLN-G2012Y?

HALANSM® HLN-G2012Y is a direct replacement CoolFlow™ plasma nozzle with OEM part number G2012Y (.11.848.221.412), compatible with Kjellberg HiFocus130i, HiFocus160i, and HiFocus280i plasma cutting systems operating at 130A with O₂ plasma gas using PerCut210M and PerCut450M "G" type torches. The nozzle is constructed from high-conductivity copper alloy, engineered to Kjellberg’s dimensional tolerances with a precision bore that constricts the plasma arc for maximum energy density. It is rated for 130A O₂ cutting and serves as the designated medium-amperage nozzle in Kjellberg’s PerCut210M/450M "G" type stack, positioned between the G101/G102 gas guide (which inserts into the nozzle) and the G3028 nozzle cap (which threads onto the nozzle).

The HLN-G2012Y works in conjunction with the G002Y cathode (20–200A) or G015Y cathode and the G4020/G4025 swirl gas cap to form a complete cutting stack. Its precision bore is calibrated to Kjellberg’s gas flow dynamics, focusing the O₂ plasma arc to deliver clean, dross-free cuts at sustained 130A production loads. The copper alloy construction provides optimal thermal dissipation, preventing bore enlargement and maintaining cut quality throughout the nozzle’s service life.

Technical Specifications

⚠️ Amperage boundary: G2012Y is rated 130A O₂. For 90A use HLN-G2010Y (.11.848.221.410). For 160A use HLN-G2014Y (.11.848.221.414). For 200A use HLN-G2016Y (.11.848.221.416). For 280A use HLN-G2326Y (.11.848.421.426). Running G2012Y below 90A or above 160A reduces bore life and risks double arcing.

Why Choose HALANSM® HLN-G2012Y

Frequently Asked Questions

1. Is HALANSM® HLN-G2012Y compatible with Kjellberg HiFocus280i?

Yes. HALANSM® HLN-G2012Y is a direct replacement for Kjellberg G2012Y (.11.848.221.412), fully compatible with HiFocus130i, HiFocus160i, and HiFocus280i plasma systems using PerCut210M and PerCut450M "G" type torches at 130A O₂. It installs in the middle of the stack: G901Y cooling tube → G002Y cathode → G101 gas guide → G2012Y nozzle → G3028 nozzle cap → G4025 swirl gas cap → G501 protection cap.

2. Is G2012Y the same as G2010Y?

No. G2012Y (.11.848.221.412) is the 130A O₂ nozzle with Ø1.2mm bore. G2010Y (.11.848.221.410) is the 90A O₂ nozzle in the same PerCut210M stack. While both fit the same torch platform, their bore geometries are optimized for different amperage ranges. Installing G2010Y at 130A causes bore overloading; installing G2012Y at 90A wastes energy density. Match the nozzle to your actual cutting amperage.

3. What gas should I use with HLN-G2012Y?

O₂ as primary plasma gas, with O₂, N₂, or Air as swirl gas. Required O₂ purity ≥ 99.5%. At 130A O₂ cutting: O₂ plasma at 0.8‐1.0 MPa, 2000–2500 L/h; swirl gas at 0.6 MPa, 1750 L/h. For Ar/H₂ stainless steel cutting, do not use G2012Y — switch to HLN-G2516 or HLN-G2725 Ar/H₂ nozzles.

4. Can I use HLN-G2012Y on HiFocus440i?

No. HLN-G2012Y is rated 130A. HiFocus440i operates at 280–400A — installing a 130A nozzle in a high-amperage system causes gas flow mismatch, arc instability, and accelerated bore wear. For HiFocus360i/440i, use HLN-G2326Y (280A), HLN-G2330Y (360A), or HLN-G2331Y (400A).

5. When should I replace the G2012Y nozzle?

Replace when: (1) Bore diameter enlarges beyond Ø1.4mm (original Ø1.2mm), causing loss of arc constriction; (2) Bore wall shows circumferential cracking or heat-discolored zones; (3) Double arcing marks appear inside the bore; (4) Cut quality drops — increased dross, wider kerf, or taper. Typical lifespan: 200–400 arc starts under sustained 130A O₂ cutting, depending on material thickness and gas quality.

6. Does G2012Y affect cut quality directly?

Yes, critically. The nozzle bore is the final constraint on plasma arc geometry. G2012Y’s Ø1.2mm precision bore constricts the O₂ plasma arc, increasing energy density and focus. This directly determines cut kerf width (±0.08mm per ISO 9013 Class 1), dross level, edge squareness, and heat-affected zone. A worn or incorrectly-sized bore causes arc root wander, increased dross, wider kerf, and tapered cuts.
