Device and energy source for MSG arc welding and/or soldering with a continously controlled power part and a step switch

摘要

The device (2) for metal-shielding gas arc welding and/or soldering, comprises an electronically controllable power source (4) with an operating unit (36) coupled over a control device (10). The operating unit has a control element, over which process parameter is selected and adjusted. A stepless controllable power section (6) of the power source is controlled, in which the control element is formed as a stepping rotary switch and/or a coding rotary switch and each switching step is assignable to a predefinable reference variable. The operating unit is coupled with a wire-feeding device.
