Abstract
In a welding torch (10) with shielding gas for arc welding with a consumable electrode, with two concentric tubes (11, 12) carrying welding current, of which the inner tube (11) serves to feed the gas and guide the electrode wire and forms with the outer tube (12) over it a first forced-flow circuit (15) for the cooling water, the inner and outer tubes (11, 12) being fastened in a current-contact-nozzle carrier (16), and also with insulation (20) which concentrically surrounds the outer tube (12) and is in turn concentrically surrounded by a casing (21) which has a gas-nozzle carrier (22) arranged on its end allocated to the current-contact-nozzle carrier (16), the service life is improved owing to the fact that the casing (21) has two concentrically arranged cooling tubes (24, 25) for forming a second forced-flow circuit (23) for the coolant, which cooling tubes (24, 25) are fastened in the gas-nozzle carrier (22) and form a cooling-water circulation channel (26, 27) in the gas-nozzle carrier (22), and that, furthermore, a water supply means (29) is attached to the inlet (28) of the second forced-flow circuit (23), the outlet (48) of which is connected to the inlet (49) of the first forced-flow circuit (15), and the outlet (54) of the first forced-flow circuit (15) is connected to the current-water return cable (55). <IMAGE>
