Sigma 630E

While the 303S is an excellent machine, it falls short in assuring complete qualtiy control on the production line. In response to several customer suggestions, Seidensha developed the SIGMA 630 portable welder. As with its sister SIGMA series machines, the 630 is equipped with Time, Amplitude, and Energy control funcitons which can be easily accessed via the LCD screen on the face of the unit.
