K4868-1 - Lincoln Invertec V276 Stick/TIG Welder (Tweco)

Industrial Reliability with the Invertec V276

The Lincoln Electric Invertec V276 is engineered to meet the rigorous demands of outdoor construction and heavy industrial fabrication. Designed with a weather-resistant IP23 rated enclosure, this machine withstands the harsh environments typical of field erection sites, ensuring consistent uptime and durability. Its compact inverter technology significantly reduces weight to just 54 lbs, making it easily transportable across job sites without sacrificing the power required for heavy-duty applications. The unit's versatility is defined by its ability to accept a wide range of input power, automatically reconnecting to 208/230/380/415/460/575V in both single and three-phase configurations, providing seamless integration into any facility or generator setup.

At the core of the V276 is its superior Stick welding performance. It is specifically tuned to excel with AWS E6010 cellulosic electrodes, allowing operators to utilize whip and drag techniques effectively, a critical requirement for pipeline and structural work. Additionally, it provides smooth, stable arcs for E7018 low-hydrogen electrodes. Beyond standard stick welding, the machine features Touch Start TIG capability, enabling high-quality TIG welds without the interference of high-frequency starting, protecting sensitive electronics nearby. For material removal and joint preparation, the V276 supports air carbon arc gouging with carbons up to 3/16 inch in diameter, making it a true multi-process solution for maintenance and repair operations.

Advanced control features allow professional welders to fine-tune the arc to their specific preferences. The Selectable Hot Start delivers an extra boost of current during arc initiation to prevent electrode sticking, particularly useful for difficult-to-start electrodes or dirty materials. The Variable Arc Force control lets the user adjust the arc characteristics from soft to crisp, optimizing the puddle control for different joint configurations and positions. With digital meters providing precise feedback on output settings, the Invertec V276 ensures that every weld meets the strict quality standards demanded by the industrial sector.
