Item Details
- The ITW / Miller / Bernard WC2HK-2 is a heavy-duty industrial water hose hook-up assembly designed to establish low-loss, high-flow thermal fluid loops between water-cooled MIG/TIG welding equipment and external closed-loop heat exchangers. The system consists of dual 30-foot conduits (supply and return) engineered to maintain duty cycle reliability for high-amperage GMAW and GTAW systems by preventing fluid pressure drops and radiant heat degradation.
Features
- Low-loss, high-flow thermal fluid loop architecture
- EPDM core resistant to glycol-based anti-freezes and deionized water
- Particulate-free internal bore prevents torch micro-channel clogging
- High-tensile braided reinforcement handles dynamic pressure spikes during pump startup
- Vulcanized outer skin resists weld spatter, cutting oils, and mechanical abrasion
- Galvanic compatibility with copper alloy heat exchangers to prevent scale formation
- Non-conductive insulation contains high open-circuit voltages (OCV) and high-frequency (HF) currents
- Kink-resistant construction ensures constant fluid flow to prevent torch thermal failure
