When fabrication shops think "bevel cutting," they often jump straight to 200A or 400A — assuming bigger amperage equals better weld prep. But for thin-gauge mild steel (the bread and butter of HVAC ducting, electrical enclosures, structural steel secondary members, and light equipment fabrication), the 80A bevel is the true sweet spot. It delivers a perfectly angled, slag-free edge on material that would warp, distort, or burn through under higher amperage — while consuming a fraction of the energy and consumable cost.
Hypertherm's official HPR130XD and HPR260XD consumables matrices both confirm the identical 80A bevel mild steel stack :
Position | OEM Part No. | HALANSM® Available | Function |
|---|---|---|---|
Shield Cap | 220637 | ✓ | Secures stack, 200–400A class cap shared with higher amperage |
Shield | 220742 | ✓ | Bevel-specific shield that maintains gas dynamics at angle |
Nozzle Retaining Cap | 220845 | ✓ | Applies precise clamping force to secure the bevel nozzle |
Bevel Nozzle | 220806 | ✓ | The star — angles the plasma arc for true bevel geometry |
Swirl Ring | 220179 | ✓ | Shared 80A–130A swirl ring; generates gas vortex for arc focus |
Electrode | 220802 | ✓ | Bevel-specific electrode — optimized hafnium insert for 80A bevel |
Water Tube | 220700 | ✓ | Bevel-specific water tube for thermal management at angle |

1. The 220806 Bevel Nozzle — Angled Precision Engineering.
The 220806 isn't just a standard nozzle with a different orifice. It's a fundamentally different geometry: the tip is machined at a specific bevel angle to direct the plasma arc precisely where the weld joint needs it . Josef Gases, an authorized Hypertherm distributor, confirms the 220806 is "rated for 80 Amps and specifically calibrated for processing mild steel" on both HPR130XD and HPR260XD, delivering "clean, smooth bevels with minimal dross" . Koike lists it as the standard 80A bevel mild steel nozzle for the HPRXD platform .
2. The 220802 Bevel Electrode — Purpose-Built, Not Adapted.
Generic suppliers often try to substitute the standard 80A electrode (220187) into bevel applications. That's a mistake. The 220802 is a dedicated bevel electrode with a hafnium insert positioned and shaped specifically for the angled arc dynamics of bevel cutting . Using a standard electrode in a bevel stack leads to off-center arc attachment, accelerated hafnium erosion, and premature electrode failure.
3. The 220742 Bevel Shield & 220845 Retaining Cap — The Support Cast.
The bevel shield (220742) and bevel retaining cap (220845) are engineered to maintain gas flow integrity when the torch head is tilted at bevel angle . A standard shield would disrupt the gas wash, causing turbulence that destroys cut quality. The 220845 retaining cap applies the exact clamping force needed to keep the 220806 nozzle seated under the mechanical stress of angled cutting.
4. The 220700 Bevel Water Tube.
Bevel cutting generates asymmetric thermal loads. The 220700 water tube is specifically routed to deliver cooling exactly where the bevel geometry concentrates heat . Using a standard water tube (220340) in a bevel stack risks localized overheating and torch head damage.
The HALANSM® 80A Bevel series is purpose-built for:
HVAC & Ductwork Fabrication — Thin-gauge mild steel ducts requiring precise bevels for flush-welded joints
Electrical Enclosure & Cabinet Manufacturing — Clean, slag-free bevels on enclosure panels for watertight welds
Structural Steel Secondary Members — Bevel prep on lighter structural elements without heat distortion
Automotive & Agricultural Equipment — Body panels and frame components requiring weld-ready edges
Robotic & Automated Weld-Prep Lines — HPR130XD robotic bevel torch leads (Hypertherm part 228487) pair perfectly with 80A bevel consumables for lights-out production
Custom Metal Fabrication Shops — Job shops where material thickness varies and 80A bevel offers the versatility to handle thin plate without burning through
Per Hypertherm's official documentation :
HPR130XD — 80A bevel mild steel cutting (fully supported)
HPR260XD — 80A bevel mild steel cutting (fully supported)
Note: The HPR130XD and HPR260XD share the identical 80A bevel stack (220637·220742·220845·220806·220179·220802·220700) . This means a single HALANSM® 80A bevel consumable inventory serves both machine platforms — a massive simplification for shops running mixed HPRXD fleets.
For shops wanting the convenience of a pre-assembled kit, Hypertherm offers the HPR130XD Mild Steel Bevel Starter Kit (130A and below) — part number 428626 . HALANSM® provides the equivalent components individually or as custom-sorted kits tailored to your production volume.
OEM-Critical Tolerances, Fractional Cost: Every HALANSM® 80A bevel component is manufactured to Hypertherm's published dimensional specifications. The 220806 nozzle's bevel angle, the 220802 electrode's hafnium concentricity, the 220845 retaining cap's clamping face — all replicate OEM geometry to micron accuracy. The result is identical cut quality at 30–50% lower cost per consumable.
Silver Cutting™ Technology: HALANSM®'s proprietary Silver Cutting™ process enhances thermal conductivity and arc stability — critical in bevel applications where the angled arc already stresses the electrode. The result is extended electrode life and more consistent bevel geometry from first pierce to last.
Downstream Protection = Real Savings: A precisely manufactured 220806 nozzle and 220802 electrode work in harmony with the 220179 swirl ring to maintain perfect gas vortex dynamics. This protects every component in the stack, eliminating the cascade failures that plague off-spec consumables. Your total cost per bevel cut drops dramatically.
Inventory Simplification: Because the HPR130XD and HPR260XD share the identical 80A bevel stack, HALANSM® lets you standardize your consumable inventory across both platforms. One purchase order. One storage bin. Zero confusion on the shop floor.
If your shop is beveling thin-gauge mild steel on an HPR130XD or HPR260XD, the 80A bevel stack is your most economical path to weld-ready edges. The HALANSM® 80A Bevel series — anchored by the 220806 bevel nozzle and 220802 bevel electrode — delivers OEM-grade cut quality and stack longevity at a fraction of genuine Hypertherm cost.
Don't let a $35 nozzle decision dictate the quality of a $50,000 weldment. Choose HALANSM® 80A Bevel consumables: the small parts that make a massive difference.
