Software notes As a traditional electromechanical welding machine based on a transformer, the TELMIG 250/2 does not have any onboard software or operating system. There is no digital interface, nor the ability to connect to the cloud or save custom programs. All adjustments are made physically via the step switches on the front panel, which allow the operator to set the voltage in six different positions and to adjust the wire feed speed using an analog potentiometer.
