The Hypertherm Inc 428618 is a comprehensive Mild Steel Consumable Starter Kit designed for the XPR300 X-Definition plasma cutting system, featuring an integrated 420221 quick-disconnect mechanized plasma torch.
Features
Integrated Quick-Disconnect XPR Torch (420221): Features EasyConnect mechanism for tool-less, single-handed coupling to torch leads
QuickLock Electrode Architecture: Utilizes a quarter-turn locking mechanism to eliminate threads, preventing cross-threading and ensuring concentric alignment
Cool Nozzle Technology: Liquid cooling pathways channel fluid directly to the nozzle tip to reduce thermal load and minimize copper ablation
Arc Response Technology: Consumable geometry works with power supply to manage ramp-down errors and eliminate high-voltage spikes during premature cut termination
ISO Range 2 Results: Maintains square cut edges and minimal angularity on thin mild steel
Resource Efficiency: Uses 64% less consumable copper mass per foot of cut compared to legacy plasma systems
Material Composition: Electrodes feature oxygen-free copper jackets with hafnium core inserts; nozzles and shields are machined from tellurium-copper alloys
Swirl Ring Construction: Precision injection-molded high-density imidized polymers for high dielectric stress resistance
