Device for inert gas shielded arc welding.

摘要

The invention relates to a device for gas-shielded arc welding, with a gas supply, a welding-wire feed device (17) and a current source (18), and recommends that a sensor (9) be arranged in the gas supply and that the welding-wire feed device (17) and/or the current source (18) by switched off by the sensor if the pressure and/or the flow of the gas falls below a threshold value.
