Invertec® STT II 208/230/460/3/60
Featuring the Surface Tension Transfer (STT) Process

Product Number:  K1525-1

Industrial Price: 7000.00 (USD) *See Details

The revolutionary 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. 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 affect 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.

Advantage Lincoln
  • 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.
  • Reduced welding costs — Ability to use 100% CO2 shielding gas with larger diameter wires.
  • Various shielding gases — STT may be used with various gas blends of Argon including Helium.
  • Good bead control and faster travel speeds — Can replace TIG (GTAW) in many applications without sacrificing appearance.
  • 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.
  • Manufactured under a quality system certified to ISO 9001 requirements and ISO 14001 environmental standards.
  • Three-year Lincoln warranty on parts and labor.
