Lincoln® Flextec® 350X PowerConnect® Multi-Process Welder (Tweco®) 6-Pack Rack K4727-2
The Lincoln® Flextec® 350X PowerConnect® 6-Pack Rack K4727-2 is a multiple operator welding rack with six 350 amp multi-process welders that are equipped with PowerConnect® and CrossLinc®. The 6-Pack Rack operates on 200-575 volt, three-phase input power, through a single electrical connection. The PowerConnect feature allows each welder to automatically detect any input power type - regardless of voltage or phase. It then optimizes the 350X to run on the supplied input electricity without any manual linking or switching. The Flextec 350X PowerConnect is capable of MIG, Pulsed-MIG, Flux-cored, DC TIG and Stick welding.
The 350X PowerConnect also comes with CrossLinc®. 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, voltage and weld process 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 350X PowerConnect can also be used will virtually all types of Lincoln wire feeders, including Lincoln ArcLink® digital feeders.
The Flextec 350X PowerConnect is built to be a rugged performer in the harshest environments. 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 6-Pack Rack comes fully assembled, with the welders pre-wired and installed. The entire rack has a single power drop. Each welder is protected by three individual 35 amp fuses. A fold-down fuse panel makes it easy to access fuses and wiring. Rugged square tube rack construction, with forklift slots and dual lifting eyes, makes this multi-operator welding system at home on any jobsite. Each individual Flextec 350X PowerConnect operates on virtually any electrical power in the world, 200-575 volt, single or three-phase. They come with Tweco® output receptacles and Lincoln's three-year warranty.

Features
Tweco® Cable Receptables
PowerConnect® Technology
Automatically connects to any input power from 200-600 volts, single or three phase.
Allows the machine to be used anywhere in the world and compensates for large fluctuations in incoming voltage.
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.
Enhanced Crosslinc® Control allows remote weld mode changes via Crosslinc, and automatic weld mode selection (Process Select Assist) based on connected Crosslinc Accessory.
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.

Software Update Capabilities
Software updates available via USB.
Multi-Process Power Source for all Your Welding Needs
Optimized stick welding for both cellulosic and low hydrogen electrodes.
Touch-Start TIG® for reducing contamination during starts without high frequency.
Compatible with ArcLink® digital feeders, CrossLinc® and 42V analog, and GMAW and FCAW.
Performs STT™ (Surface Tension Transfer) when paired with a Lincoln Activ8X™ pipe wire feeder.
Performs pulsed-MIG welding when paired with a Lincoln ArcLink® digital wire feeder
