Lincoln Invertec STT II Power Source From Lincoln Electric: The revolutionary STT II power source combines high frequency inverter technology with advanced Waveform Control Technology to provide a better welder solution than traditional short arc MIG. Unlike CV Mig machines, the STT machine has no voltage control knob. STT uses current controls to adjust the heat independent of the wire feed speed, so changes in electrode extension do not effect heat. Low heat input welds can be produced without overheating or burning through, and distortion is minimized. Spatter and fumes are reduced because the electrode is not overheated - even when welding with larger diameter wires and 100% co2 shielding gas. These units are set up at 440 volt, 3 phase. Feeders recommended for these units are the STT-10, LN-742 (2 roll), LN-742 (4 roll) and the LN-15 control cable model. We do have some LN-742 (4 roll ) feeders available at an additional cost. Email us or call Mark Griffith at ext 470 for further questions. All Items are subject to prior sale!! |
