Electronic welding source avoiding disturbing electromagnetic forces - whose working parameters are remote controlled to avoid excessive electromagnetic force build-up

摘要

Electronic welding source in which the operational parameters are remote controlled by guiding voltages. The remote control signals can control the time constant and/or dynamic conditions of a dynamic modulus, the statistical volt-current characteristic line of a static modulus and the free burning time and/or the gas flow time. ADVANTAGE - By avoiding long connection circuits to control the process parameters, disturbing electromagnetic forces are avoided.
