Description

Chalumeau de coupe à trois tuyaux DONMET 374-10 à levier (G1)

Chalumeau de coupe oxy-gaz à trois tuyaux avec mélange des gaz dans la buse et levier d’oxygène de coupe.
Utilisé pour la découpe manuelle oxy-gaz de l’acier faiblement allié jusqu’à une épaisseur de 300 mm, ainsi que pour le chauffage local de tous types de métaux ou alliages.

Buses compatibles : G1A, G1P, HP1, DH1.
Livré sans buses.

Permet une découpe précise et de haute qualité avec des performances maximales.

Caractéristiques techniques :

  • Nouvelle conception légère offrant de meilleures performances avec un minimum d’effort.
  • Corps entièrement soudé et tubes en acier inoxydable garantissant rigidité, solidité et durabilité du chalumeau.
  • Utilisation de soudures à l’argent permettant un fonctionnement continu dans des conditions difficiles et des espaces confinés sans compromettre l’intégrité de la structure.
  • Design universel permettant de changer rapidement de type de gaz (acétylène, propane-butane, gaz naturel) en remplaçant simplement la buse.
  • Poignée ergonomique offrant une prise ferme sur le manche du chalumeau et une manipulation aisée dans toutes les positions spatiales.
  • Levier d’oxygène de coupe avec verrouillage en position « ouvert » permettant d’économiser jusqu’à 15 % d’oxygène lors de coupes courtes et d’assurer un confort pour les coupes longues.
  • Rentabilité accrue par rapport aux chalumeaux à injection classiques grâce à la conception élaborée des buses.
  • Ajustement parfait de l’équilibre par rapport à la main de l’opérateur, facilitant les découpes fines et le contrôle du processus.
  • Positionnement pratique des soupapes avec un code couleur distinctif (bleu pour l’oxygène et rouge pour le gaz combustible), permettant un réglage rapide de la flamme de préchauffage.
  • Design soigné combinant fonctionnalité, fiabilité et sécurité indispensables.

Le chalumeau de coupe est de type universel pour les gaz combustibles utilisés – en fonction de la buse montée, il peut fonctionner au propane-butane, méthane (gaz naturel) ou acétylène.

Sécurité et durabilité
La conception du chalumeau est reconnue comme l’une des plus sûres, car le gaz combustible et l’oxygène sont acheminés séparément par des tuyaux, d’abord vers la tête du chalumeau, puis vers les buses où les gaz se mélangent. Cette conception permet une utilisation sécurisée sans risque de combustion interne du mélange oxy-gaz dans le tube mélangeur, un problème fréquent avec les chalumeaux à injection en cas d’urgence. Le risque de retour de flamme est minimisé et les conséquences graves sont éliminées.

Les tubes du chalumeau sont fabriqués en acier inoxydable, ce qui les protège de l’oxydation et de la détérioration. La tête et le manche en laiton garantissent une grande durabilité. Les tiges des soupapes en acier inoxydable assurent une durée de vie des soupapes d’au moins 45 000 cycles « ouverture-fermeture ».

Compatibilité et contenu de la livraison
La buse n’est pas incluse dans le kit de livraison mais peut être commandée séparément en fonction de l’épaisseur de coupe. Ainsi, il n’est pas nécessaire de payer pour des équipements inutiles – les utilisateurs peuvent choisir les buses adaptées à leurs besoins.
Le chalumeau est compatible avec les buses G1A, G1P, HP1, DH1.

 

 

Oxy-gas three-pipe cutting torch with in-nozzle gas mixing and a cutting oxygen lever.
Used for hand oxy-gas cutting of low carbon steel up to 300mm thick, as well as for local heating of any metals or alloys.

Compatible cutting nozzles: G1A, G1P, HP1, DH1.
Supplied without nozzles.

Facilitates an accurate high-quality cut at maximum performance.
Technical features:
– new light-weight design allows for greater performance at minimal effort
– fully soldered body and stainless steel tubes ensure cutting torch rigidity, solidity and durability
– use of silver solders allows for continuous operation in hard conditions as well as confined areas without damaging the design integrity
– universal design allows to quickly switch to another type of gas (acetylene, propane-butane, natural gas) by simply changing the nozzle
– convenient ergonomic handle allows for a firm grip on the cutting torch shank and easy operation in all spatial positions
– cutting oxygen lever with a lock in “open” position allows to save up to 15% of oxygen while performing short cuts as well as comfortably perform long cuts
– increased cost-efficiency as compared to ordinary injection-type cutting torches due to nozzles’ elaborate design
– perfect balancing adjustment relative to the cutter’s hand allows to perform fine cuts and control the process easily
– comfortable positioning of the valves and their bright colouring (blue for oxygen and red for gas fuel) allows to quickly adjust the preheating flame
– exquisite design that combines the necessary functionality, reliability and safety

The cutting torch is a universal type as per used gas fuels – depending on the nozzle mounted to the head it can operate on propane-butane, methane (natural gas) and acetylene.
Safety and durability
The cutting torch design is rightfully considered to be the safest one as gas fuel and oxygen are supplied by separate tubes – first to the cutting torch head and then to the nozzles where the gases get mixed. Such design allows for safe operation of the cutting torch without the risk of internal combustion of the oxy-gas mixture inside the mixing tube that is incidental to injection-type cutting torches in emergency situations. The danger of flashbacks is minimized and severe affects are eliminated. The cutting torch tubes are made of stainless steel which prevents their oxidation and destruction, the head and the shank are made of brass which ensures high durability. Valve stems made of stainless steel ensure the valve’s operational life of no less than 45 000 “open-closed” cycles.
Compatibility and scope of delivery
The nozzle is not included in the delivery set but can be ordered separately depending on the cutting thickness. Thus, there is no need to overpay for unnecessary kitting – the users can choose the nozzles as required by the task at hand. The cutting torch is compatible with nozzles G1A, G1P, HP1, DH1.
