Lincoln Electric Flextec 350X PowerConnect Multiprocess Welder, LF-74 One-Pak
The Lincoln Electric Flextec 350X PowerConnect / LF-74 One-Pak bundles the PowerConnect multiprocess power source with an LF-74 wire feeder, drive rolls, a gun, cables and a regulator under one part number. Suited to CV MIG welding in the shop, it accepts 200-600 V input, single- or three-phase, and delivers a 5-425 A output range.
The LF-74 handles basic wire welding, while the power source supports stick, TIG, MIG, pulsed MIG, self- and gas-shielded flux-cored welding and gouging. Rated output is 350 A at 34 V and a 60% duty cycle on three-phase input and on single-phase 380-575 V, or 300 A at 32 V and 60% on single-phase 200-230 V.
Feeder communication covers analog, digital, CrossLinc and ArcLink with a 40 V DC feeder supply, and the work lead connector is Tweco. Net weight is 154 lbs (69.9 kg) and dimensions are 17 x 13 x 24 in. (H x W x D). Typical applications include construction, cross-country pipeline, general and heavy fabrication, heavy equipment, maintenance and repair, offshore, and oil and gas.
