Why buy this machine? The time-tested industry standard for multiprocess welding, providing best of class Stick performance, Flux Cored( FCAW), MIG, TIG and Carbon Arc Gouging. Great for maintenance and repair, sheet metal, process piping, fabrication and manufacturing.   A simplified version of the full featured model, the XMT-350 VS is ideal for Construction or Fabrication applications utilizing voltage sensing wire feeders without remote control. The units increased weld output enables improved deposition using Flux Cored/Tubular wire. True "CV" MIG welding and superior "CC" Stick, Carbon Arc Gouging and TIG welding capability are all possible with the XMT-350 VS   The XMT 350 CC/CV provides the multi-process capability you expect from an XMT with the added benefits of higher output (350A) and Auto-line Technology (208-575V input with no linking) This means no lost set up time, no annoying arc outtages or trips due to line voltage fluctuations and elimination of power source failures due to incorrect manual linking.Great for heavy/all manufacturing, fabrication, construction, structural, maintenance, sheet metal and process piping.   The XMT 350 MPa with Built-in Pulse MIG programs can handle virtually any welding job, including the hard-to-weld alloys found in shipbuilding and power generation applications. Its all here, GMAW-P, GMAW, SMAW, FCAW, GTAW along with all the other XMT 350 Family features. Great for heavy/all manufacturing, fabrication, construction, structural, maintenance, sheet metal, process piping.   The most welding output of any XMT welding power supply, capable of supplying power for large 3/8" carbons for Air Carbon Arc Cutting and Gouging. Its ability to supply up to 600 Amps makes it the machine of choice feeding larger diameter wire and stick electrodes (GMAW, GMAW-P, FCAW, SMAW) Great for heavy/all manufacturing, fabrication, construction, structural, maintenance, sheet metal, process piping.

Power Management Technology
Primary Technology

Auto-Link®

Better

Automatically links/enables the unit for operation, on any of two primary voltages. (230/460 or 460/575 VAC, single or three phase)

upgrade

Auto-Line™

Best

Allows for any primary voltage (208-575 VAC) to power unit. No primary linking required, providing convenience in any job setting. Ideal solution for dirty or unreliable input power.

 

Auto-Line™

Best

All XMT-350 models provide Auto-Line™ Power Management Technology for the maximum degree of freedom over primary power fluctuation. (+37%,-59% on 460 VAC)
