Lincoln Electric Flextec 350XP Multiprocess Welder, Tweco
The Lincoln Electric Flextec 350XP is a portable multiprocess power source that adds pulsed MIG to the 350X Construction when it is paired with a compatible ArcLink digital wire feeder such as the Power Feed 84. It supports MIG, TIG, stick, flux-cored and carbon arc gouging. This version is the Tweco configuration.
Standard Amphenol connections let it work with most Lincoln Electric wire feeders. That includes CrossLinc feeders, across-the-arc feeders, 14-pin analog units and 5-pin digital ArcLink units. Pulsed MIG modes unlock once a compatible ArcLink-capable feeder, such as the Power Feed 84, is connected.
CrossLinc technology is included, so output can be controlled remotely over the standard weld cables with a compatible CrossLinc accessory and no separate control cable. The operator panel is streamlined for quick setup, internal components are designed to run cool in high-temperature settings, and output connections are Tweco style. IP23 weather protection and Desert Duty certification suit harsh outdoor environments.
