<p>This patent application describes both a method, using a vehicle's standard electric equipment, with which it is possible to perform arc welding, and a device that facilitates switchovers between normal vehicle operation and welding without modification of the standard equipment. The device includes an electrode holder (6) with built-in rectifier (5) and a multifunction selector (14) which in one step takes care of all switchovers necessary for welding. In a special form of design, there are two independent sources of current, one with low-voltage direct current and one with, in relation to the former, high-voltage direct current. These two sources of current are made to work together according to this invention so that arc welding can be performed.</p> |
