Lincoln® Flextec® 350X Construction Multi-Process Welder (Tweco®) K4271-2
The Lincoln® Flextec® 350X Construction K4271-2 is a 350 amp multi-process welder with CrossLinc®, that is capable of MIG, Flux-cored, DC TIG and Stick welding. Built-in CrossLinc® technology means that the Flextec 350X communicates with an
OPTIONAL CrossLinc remote or Lincoln X Series voltage-sensing wire feeder directly through your welding leads. Full remote amperage and voltage control is achieved without the use of a separate remote-control cable. Standard voltage sensing wire feeders may also be used, but CrossLinc remote control functionality will be disabled.
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.

Features
Tweco®-Style Cable Receptables
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.
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.
Touch-Start TIG® for reducing contamination during starts without high frequency.
Field Proven Ruggedness and Durability
Engineered for outdoor use and harsh environments.
IP23 rated for use in outdoor weather conditions.
Desert Duty rated for operation at temperatures up to 55° C (131° F).
Trayed and potted PC boards to help withstand welding dust and humidity.
Smart fans run at variable speeds to keep internal machine components cool.
Tough alloy handles for lifting and impact protection.
Lightweight aluminum powder painted case for rust protection.
Shock Absorbing Rubber Feet for impact protection
PLEASE NOTE: This is a DC TIG welder ONLY. It CANNOT TIG weld aluminum.
