Welding power source with improved functional robustness

Abstract:

A welding current source (1) having a housing (10) formed from metallic material, a welding inverter (50), a digital, electronic welding process computation unit (20) and a man-machine interface device (30), wherein the welding process computation unit (20) is set up to actuate the welding inverter (50), wherein the welding process computation unit (20) and the welding inverter (50) are arranged in the housing (10) and the man-machine interface device (30) is mounted on the welding current source (1) outside the housing (10), wherein the welding current source (1) additionally has a digital, electronic man-machine computation unit (40) mounted on the welding current source (1) outside the housing (10), and wherein the man-machine interface device (30) is connected to the man-machine computation unit (40), and wherein the man-machine computation unit (40) and the welding process computation unit (20) are networked to one another via a communication link (60) and form a computer network.
