USED Lincoln Invertec STT-II / LF72 Mig Package

Featuring Surface Tension Transfer® (STT®) Process

The Invertec® STT® II power source combines high frequency inverter technology with advanced Waveform Control Technology® to provide a better welding solution than traditional short arc MIG.

Controlled penetration and outstanding heat input control – Ideal for welding joints with open root, gaps, or on thin material with no burnthrough. 

Reduced spatter and fumes – Current is controlled to achieve optimal metal transfer.

Various shielding gases – STT® may be used with various gas blends including 100% CO2 and Argon or Helium blends. Larger diameter wires can typically be used.

Good bead control and faster travel speeds – Can replace TIG (GTAW) in many applications without sacrificing appearance or quality.

Background and Tailout Current – Accurately control fine and coarse heat input for reduced distortion and burnthrough as well as proper penetration.

Adjustable Hot Start – controls the heat at the start of the weld.
