Cooled Electrode Holders TRIZ Cases

Resistive preheating through dual contact tips warms the electrode wire, cutting arc energy demand and improving submerged arc welding efficiency.

Silver-zirconium or silver-hafnium wear alloys raise electrode burn-back limits, extending plasma torch life under high thermal loads.

Internal gas cooling channels in a plasma torch nozzle replace external cooling hardware, stabilizing high-current arcs and extending consumable life.

A single connector combines welding power, shielding gas, and coolant lines while routing coolant through the bezel to prevent ingress.

Parallel power conductors inside coolant lines cut torch weight and stiffness while lowering cable resistance and insulation stress.

A ceramic isolation sleeve constrains TIG arc path and diffuses heat to reduce arc wander and improve weld consistency.

Inclined center-pipe surfaces guide coolant to the hottest electrode region, boosting cooling while limiting pressure loss and pump load.

Dual contact tips and insulated current paths resistively preheat electrode wire, lowering arc energy while preserving retrofit compatibility.

Electrode guides and a translatable coolant tube keep plasma torch consumables aligned under high coolant pressure while fitting different electrode lengths.

Electrode guides and coolant pressure keep plasma torch consumables centered under high flow, improving alignment, life, and cutting performance.

Indented inner coolant channels increase electrode heat transfer area, slowing plasma torch wear and reducing replacement frequency.
