Lincoln® Flextec® 350X Construction / LN-25X® One Pak® K4278-3
The Lincoln® Flextec® 350X Construction / LN-25X® One Pak® is a complete 350 amp multi-process welder / voltage-sensing wire feeder package. The system includes a Flextec 350X Construction multi-process welder that is capable of MIG, Flux-cored, DC TIG and Stick welding. It also comes standard with an LN-25X® voltage sensing wire feeder with CrossLinc®, and Magnum® PRO Curve™ HDE™ MIG welding gun.
Built-in CrossLinc® technology included in both the welding power source and the feeder means that the Flextec 350X communicates with the LN-25X wire feeder directly through your welding leads. Full remote amperage and voltage control is achieved without the use of a separate remote-control cable. This completely eliminates the need to go back to the welding machine to make output voltage adjustments.
The Flextec 350X Construction is built to be a rugged performer on the harshest job sites. It is rated IP23 for welding in outdoor weather conditions. The 350X also comes with Lincoln's Desert Duty® certification, meaning it can keep welding in temperatures up to 131 degrees F. Heavy duty alloy carrying handles, powder-coated aluminum case and shock absorbing rubber feet make this an impact resistant power source that will stand up to abuse.
The Flextec 350X Construction operates on 380-575 volt, three-phase input power and comes with Tweco®-style cable receptacles and Lincoln's three-year warranty.
The LN-25X wire feeder comes standard with TVT™. True Voltage Technology compensates for voltage drops common with long welding cable runs. TVT automatically detects welding voltage variations and adjust on-the-fly, to provide a smooth consistent arc, even if you are far away from the welder itself. The LN-25X wire feeder has up to a 450 amp welding capacity. It features Lincoln's MAXTRAC® wire drive system, to ensure smooth wire feeding and excellent electrical contact with your welding gun. It comes complete with Magnum® PRO Curve HDE™ 250 amp MIG gun with 15 foot leads and .045 drive rolls for cored-wire.Processes

CrossLinc® with True Voltage Technology™
CrossLinc® allows for amperage and voltage control at the welding arc to improve control of your operation.
No need for an additional control cable communication occurs directly over the weld cables.
True Voltage Technology™ compensates for voltage drop across the welding circuit.
TVT™ will measure the voltage drop and adjust the power source to compensate for the difference between the desired voltage and actual voltage at the weld.
Flextec® 350X Construction Multi-Process Power Source for all Your Welding Needs
Optimized stick welding for both cellulosic and low hydrogen electrodes.
Compatible with CrossLinc, 42V analog, and digital feeders for GMAW and FCAW.
