The 200A O₂ Nozzle Across Three Hosts: Airgas confirms 220831 as "Hypertherm® 200 Amp Oxygen Nozzle For Use With HyPro2000, MAXPRO200®" . Hypertherm's own HT2000 retrofit torch consumables chart places 220831 at the 200A O₂ position , and the native MAXPRO200 matrix does the same .
Oxygen-Only by Design: 220831 is engineered specifically for oxygen plasma gas cutting mild steel — the O₂ chemical reaction with the base material accelerates the cut and produces a smooth, low-dross edge . For 200A air cutting (mild steel / stainless / aluminum), the correct nozzle is 420044, not 220831 . This distinction matters: fitting a 220831 on an air stack, or a 420044 on an O₂ stack, degrades cut quality and shortens consumable life.
Arc Constriction = Cut Speed: The nozzle's primary job is to shape, direct, and constrict the plasma arc . The HALANSM 220831 reproduces Hypertherm's micron-level orifice geometry so the 200A O₂ arc stays tightly focused — delivering the fastest pierce and cut speeds in the MAXPRO200 family's 200A class.

HALANSM® 220831 Nozzle — 200A Oxygen for HyPro2000 Upgrade Torch for HT2000 / MAX200 / MAXPRO200
The HALANSM® 220831 is the designated 200A oxygen nozzle for Hypertherm's HyPro2000 upgrade torch mounted on the HT2000 platform, the HyPro2000 retrofit on MAX200, and the native MAXPRO200 . As the component that shapes, directs, and constricts the plasma arc , the nozzle directly governs cut speed, edge squareness, and dross levels at the 200A class. Constructed from high-purity copper-chromium alloy with an integrated red high-temperature seal ring , the 220831 is optimized for one thing: fast, clean oxygen-plasma cutting of mild steel.
Why 220831 is the right nozzle for 200A O₂ work
Across all three host platforms, Hypertherm's official consumables matrices place the 220831 at the 200A O₂ position:
HyPro2000 upgrade torch for HT2000 — 200A O₂ (mild steel): 220832 shield · 220936 shield cap · 220831 nozzle · 220834 swirl ring · 220937 electrode · 220521 water tube · 220935 retaining cap (without tab)
HyPro2000 upgrade torch for MAX200 — 200A O₂: same stack as above
Native MAXPRO200 machine torch — 200A O₂ (mild steel): 420059 shield · 220935 shield cap · 220831 nozzle · 220834 swirl ring · 220937 electrode · 220521 water tube
Airgas and Welding Supply both confirm the same cross-platform identity: "Hypertherm® 200 Amp Oxygen Nozzle For Use With HyPro2000, MAXPRO200®" ; "For use with MAXPRO200/HyPro2000 200A. The primary function of the nozzle is to shape, direct, and constrict the plasma arc." . One nozzle, three host torches, one gas process — oxygen.
Key Features
Precision Orifice for High-Current Constriction: The micron-level precision of the central orifice guarantees a highly focused plasma arc . At 200A, this focus translates directly into faster pierce and cut speeds on thick mild steel while minimizing dross adhesion on the underside of the cut — the single biggest driver of throughput in heavy fabrication.
Oxygen-Specific Gas Dynamics: The 220831's internal geometry is tuned to the specific flow characteristics of oxygen plasma. O₂ cutting on mild steel produces a chemical exothermic reaction with the base material that accelerates the cut and yields a smooth edge with minimal dross . A nozzle designed for air (like the 420044) would not channel O₂ flow optimally — which is why Hypertherm specifies 220831 for O₂ and 420044 for air at 200A .
Advanced Material Stability: The high-purity copper-chromium alloy body offers exceptional thermal conductivity to dissipate the extreme heat of a 200A arc . This extends operational lifespan even under continuous heavy-duty industrial use — critical in shipbuilding, structural steel, and heavy machinery fabrication.
Leak-Proof Integrated Seal: The built-in high-temperature red seal ring creates a perfect gas-tight barrier between the nozzle and the 220834 swirl ring . This maintains consistent gas flow and arc stability for superior cut finishes, preventing the gas bypass that causes arc wander and premature electrode wear.

NOTE: 220831 = 200A oxygen nozzle. Compatible hosts: HyPro2000 upgrade torch for HT2000, HyPro2000 retrofit on MAX200, and MAXPRO200 machine torch — all at 200A O₂ for mild steel cutting . This nozzle is oxygen-specific; for 200A air cutting (mild steel / stainless / aluminum), use nozzle 420044 instead . For 200A O₂ bevel processes on MAXPRO200, use nozzle 420733 . The 220831 pairs with electrode 220937, swirl ring 220834, and shield 220832 (HyPro2000) or 420059 (MAXPRO200) . Always inspect the nozzle orifice for roundness and wear when cut quality degrades — a worn nozzle causes arc wander, double-arcing, and accelerated electrode erosion . HALANSM® is an independent aftermarket manufacturer; this part is a compatible replacement for Hypertherm® systems.
