ADVANCED PROCESS WELDERS Invertec STT II ® ®
www.lincolnelectric.com/green
Featuring Surface Tension Transfer (STT ) Process The Invertec®
® ® STT® Waveform Control Technology®
• 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. Product

Power Wave C300 ®
www.lincolnelectric.com/green
Portable. Powerful. Compact. One Machine Does it All! The Power Wave®
C300 is an advanced compact multi-process power
source with an integrated wire feeder. It’s ideal for welding on a wide variety of materials, including aluminum, stainless, and nickel materials – where arc performance is critical.
• PowerConnect™ Technology (Patent-Pending) – Automatically
adjusts to input power from 200-600V, 50 or 60 Hz, single phase or three phase. Welding output remains constant through the entire input voltage range.
• Tribrid™ Power Module – Exceptional welding performance
with high power factor and efficiency. • Production Monitoring™
2 – Track equipment usage, store
weld data and configure fault limits to aid in production analysis and process improvements.
• Compact and Durable Case – IP23 rated to withstand harsh environments.
• Integrated TIG Torch and Spool Gun Solenoid – Makes for fast changeovers to TIG welding or spool gun operation.
