Title (EN) IMPROVED COOLING FOR INVERTER-BASED ENGINE-DRIVEN WELDING-TYPE POWER SUPPLY
(FR) REFROIDISSEMENT AMÉLIORÉ POUR ALIMENTATION ÉLECTRIQUE DE TYPE SOUDAGE MOTORISÉE À BASE D'ONDULEUR
Abstract:
(EN) A welder-generator comprising an engine operatively coupled to a generator (128), weld circuitry (116), and a cooling system. The generator (128) is configured to produce an electrical signal. The weld circuitry includes inverter circuitry configured to control characteristics of the electrical signal. A cooling system is configured to substantially block heat generated by operation of the engine from being transmitted to the weld circuitry.
(FR) Un générateur de soudeur selon l'invention comprend un moteur relié de manière fonctionnelle à un générateur (128), des circuits de soudage (116) et un système de refroidissement. Le générateur (128) est configuré pour produire un signal électrique. Le circuit de soudage comprend des circuits d'onduleur configurés pour commander des caractéristiques du signal électrique. Un système de refroidissement est configuré pour empêcher sensiblement que la chaleur produite par le fonctionnement du moteur soit transmise aux circuits de soudage.
