Field of the Invention The present invention relates to a welding torch for arc welding with intense contact tip cooling, comprising a torch body, a contact tip holder, a contact tip, sealing elements and an energy supply. The purpose of the invention is to allow the welding and welding of arc welding without interrupting the welding process from the overheating of the contact tip and the entire burner, removing the jamming of the welding wire in the contact tip and allowing it to be welded with large welding currents, which greatly increases labor productivity.

Zvárací horák pre oblúkové zváranie s intenzívnym chladením kontaktnej špičky sa vyznačuje tým, že kontaktná špička je rozoberateíne spojená s držiakom kontaktnej špičky tak, že nimi vytvořený kanál pre chladiace médium je v držiaku kontaktnej špičky priebežný a uzavretý samotnou kontaktnou špičkou. Medzi držiak kontaktnej špičky a kontaktnú špičku sú vložené tesnenia pre zamedzenie úniku chladiaceho média.The contact tip arc welding torch is characterized in that the contact tip is detachably connected to the contact tip holder so that the coolant channel formed therein is continuous in the contact tip holder and closed by the contact tip itself. Seals are inserted between the contact tip holder and the contact tip to prevent coolant leakage.

Vynález, sa týká zváracieho horáka pre oblúkové ranie s intenzívnym chladením kontaktnej špičky, pozostávajúceho z telesa horáka, držiaka kontaktnej špičky, kontaktnej špičky, tesniacich elementov a přívodu energií. \ súčasnej době sú známe zváracie horáky pre oblúkovú technológiu, kde kontaktná špkka je chladená nepriamo chladiacim médiom, t. j. že chladiace médium neobteká kontaktnú špičku, ale prúdi len v držiaku kontaktnej špičky. Tento spósob chladenia kontaktnej špičky je nedostačujúci, kontaktná špička sa zahrieva, čo je příčinou zasekávania sa drótu v kontaktnej špičke. Odstraňováním porúch narastajú stratové časy, čím sa znižuje produktivita práce a zvyšuje pracnost opravovania. Dalšia nevýhoda súčasného chladenia kontaktnej špičky je, že neumožňuje zvyšovat’ zvárací prúd nad hodnotu, kedy vzniknuté teplo pri zváraní akumulované v špičke je v rovnováhe s teplom odvedeným vedením cez kontaktnú špičku do chladiaceho média.The present invention relates to a welding torch for arc contact intensive cooling of a contact tip consisting of a torch body, a contact tip holder, a contact tip, sealing elements and an energy supply. Nowadays, arc torch welding torches are known, where the contact chip is cooled indirectly by the cooling medium, i.e. the cooling medium does not bypass the contact tip but only flows in the contact tip holder. This method of cooling the contact tip is inadequate, the contact tip being heated, causing jamming of the wire at the contact tip. By eliminating the failures, the loss of time increases, which reduces labor productivity and increases repair effort. A further disadvantage of the current contact tip cooling is that it does not allow the welding current to rise above a value where the heat generated during peak-accumulated welding is in balance with the heat conduction through the contact tip to the cooling medium.

Vynálezom sa uvedené nevýhody do značnej miery odstránia. Podstata vynálezu je v konštrukčnom převedení zváracieho horáka pre oblúkové zváranie s intenzívnym chladením kontaktnej špičky. Zvárací horák podl’a vynálezu pozostávajúci z telesa horáka, držiaka kontaktnej špičky, kontaktnej špičky, tesniacich elementov a přívodu energií má kontaktnú špičku rozoberatelne spojená s držiakom kontaktnej špičky tak, že nimi vytvořený kanál pre chladiace médium je v držiaku kontaktnej špičky priebežný a uzavretý kontaktnou špičkou. Medzi držiak kontaktnej špičky a kontaktnú špičku sú vložené tesnenia pre zamedzenie úniku chladiaceho média.These disadvantages are largely eliminated by the invention. The essence of the invention is in the design conversion of a welding torch for arc welding with intensive contact tip cooling. The welding torch according to the invention, consisting of a torch body, a contact tip holder, a contact tip, sealing elements and an energy supply, has a contact tip detachably connected to the contact tip holder so that the coolant channel formed therein is continuous in the contact tip holder and closed by the contact tip. Seals are inserted between the contact tip holder and the contact tip to prevent coolant leakage.

Zvárací horák podlá vynálezu má viaceré výhody. Umožňuje zvárať a navárať bez prerušenia zváracieho procesu z dóvodu prehriatia kontaktnejThe welding torch according to the invention has several advantages. It allows welding and welding without interrupting the welding process due to contact overheating
