DEVICE AND METHOD OF CONNECTION OF INPUT OF PLASMA ARC TORCH WITH SUPPLY SOURCE Russian patent published in 2007 - IPC B23K9/32 B23K10/00 H05H1/34 

FIELD: mechanical engineering; welding.

SUBSTANCE: invention relates to extension of input of torch for gas-electric welding and plasma mechanical machining which contains pipeline with distal end and proximal end. Distal connecting element is arranged on distal end of pipeline, and proximal connecting element is arranged on proximal end of pipeline. Distal connecting element is made for engagement with connecting element of torch input secured on proximal end of torch input. Proximal connecting element is made for engagement with connecting element of supply source. Distal connecting element and connecting element of torch input form quick-release joint, and proximal connecting element and connecting element of supply source form quick-release proximal joint. So, torch input extension can be quickly installed between input of torch and supply source and disconnected from input of torch and supply source.

EFFECT: possibility of welding on objects arranged at distance from supply source of torch.
