The 420273 Shield is the outer protective sleeve for Hypertherm XPR300/XPR170 stacks running 220A mild steel (O₂/Air). It locks alignment, protects the nozzle/electrode from spatter and heat, and preserves the gas column so your edge stays straight and dross stays manageable—while letting you run longer between changeouts.

Shield 420273 for Hypertherm XPR300 Plasma Cutting Torch Consumables 220A
The shield is the outermost sleeve of the torch head. Its job is simple but critical: keep the nozzle/electrode stack aligned, protect internals from molten spatter, and maintain the correct standoff so the gas path—and therefore the arc—stays stable on thicker plate.
Key Features
220A O₂/Air Geometry: Bore/length/contour follow the XPR300 mild‑steel 220A envelope so gas forms correctly and you don’t chase “random edge change.”
Precision O‑Ring Lands (via 420200/retaining interface): Smooth seat surfaces help prevent cooling‑water weep and gas bypass—two silent killers of cut stability.
High‑Purity Copper: Better thermal mass/conductivity than soft/impure copies; resists heat creep and keeps the stack truer for more cuts per set.
Drop‑In Fit: Built to the OEM envelope so it seats correctly with Retaining Cap 420200 / 420365 and the rest of the 220A stack.
