The burner of the claimed design works as follows.

Pre-installed departure electrode 11 with respect to the ceramic nozzle 14, and then configures the burner by turning chocolatepuma tube 2 around the longitudinal axis of the arm 4 and the rotation of the welding head around the conical tip 18 at the angle defined by the welding unit 28.

By pressing the button 26 includes a voltage from a power source (not shown) and the supply of protective gas, for example argon, chocolatedkodm 1 to the housing 9 of the welding head through the header 3, chocolaterie tube 2 and the lugs 18.

ofreeing chocolatepuma tube 2, which is moved in the gap between the inserts 16 in the transverse relative to the longitudinal axis of the handle 4 direction. The lugs 18 due to the elasticity chocolatepuma tubes 2 extend from mating with the holes 20, the weld head is removed and replaced with another, the lugs 18 are inserted through the depression 21 in the holes 20, then the welder by the lock 6 compresses the tube 2, locking them.

Thus, compared with the prototype of the proposed burner provides the best quality of welded joints due to the fixation chocolatepuma pipes and the welding electrode, and also meets the safety requirements.
