Splet31. avg. 2014 · The short-circuit mode can be used to produce relatively low heat input welds, with lower distortion levels than that achievable with other GMAW modes. The process uses conventional GMAW equipment and has a limited number of controls, making it very user friendly. SpletWhen the electrode touches the weld pool (A) a short circuit is created, the arc extinguishes, the voltage decreases and the current increases into the short circuit. This causes the drop to be released (B).
