Miller XMT 350 FieldPro Polarity Reversing Welder (Tweco) 907731

Miller® XMT® 350 FieldPro™ Polarity Reversing Multiprocess Welder (Tweco®) 907731

The Miller® XMT® 350 FieldPro™ Polarity Reversing (Tweco®) is a portable 350 amp multi-process welder that features automatic polarity reversing, which is based on your welding application. Built-in polarity reversing means you'll never have to spend time switching weld cables, just because you're changing welding jobs. Go from MIG, Flux-Cored, stick or TIG with the press of a process button. Cumbersome welding cable changeovers are a thing of the past.

The XMT 350 FieldPro Polarity Reversing also communicates with a remote Miller® ArcReach® wire feeder or Stick/TIG remote without the use of a remote control cable. The secret to this technology is built-in circuitry in both the XMT 350 FieldPro welder and ArcReach wire feeder/remote that passes remote signals through the welding leads, eliminating the need for costly remote control cables. ArcReach remote control distance is limited only by the length of your welding cable leads. ArcReach allows your welding operation to take place further away from the welding power source, and reduces downtime and costs by giving the operator full remote control capabilities at the site of the weld. The XMT 350 FieldPro MUST be paired with a Miller ArcReach feeder/remote to get the full benefits of this feature.

The XMT 350 FieldPro Polarity Reversing is capable of MIG, stick and DC TIG welding. It operates on both three-phase and single-phase input power and features Miller's Auto-Line,™ which means you use 208 volt to 575 volt, single or three-phase input power without manual linking.

Weighing just 93 pounds, the XMT 350 FieldPro is easy to move around the shop or jobsite and its rugged case design ensures it will stand up to the punishment of extreme work environments. It is ideal for industrial applications. It is able to carbon arc gouge with carbons up to 5/16" diameter. When paired with a wire feeder or spool gun, the XMT 350 FieldPro makes an excellent MIG and Flux-Cored welder. It's got built-in Lift-Arc™ TIG arc starting for smooth DC TIG arc starts without the use of high frequency.

Features

Built-In Polarity Reversing
Streamlined and simplified process changeover eliminates the need for swapping cables. The robust design withstands harsh environments common in the field.

Remote control of the power source without a cord -
ArcReach® technology uses the existing weld cable to communicate welding control information between the feeder and power source. This technology eliminates the need for control cords, and their associated problems and costs.

Cable Length Compensation (CLC™)
Makes proper setup of weld parameters faster; automatically adjusting voltage based on weld cable length. This ensures that the voltage a welder operator sets is the voltage they get.

Adjust While Welding (AWW™)
Allows operators to make precise adjustments even while a weld bead is being laid, which allows parameters to be changed while the arc is on.

RMD® and pulsed welding without control cords
Operate up to 200 feet away from the power source with an OPTIONAL ArcReach® Smart Feeder.

Auto-Bind
Automatically establishes an exclusive communication between the power source and the wire feeder, using the existing weld cables upon system power up.

Auto-Line™
Provides state-of-the-art flexibility by automatically connecting to 208-575 VAC, single- or three- phase power without removing the covers to re-link the power source. No longer is there a concern if you have the correct machine for the shop or the job site.

Wind Tunnel Technology™
Internal air flow that protects electrical components and PC boards from dirt, dust and debris… greatly improving reliability.

Fan-On-Demand™
Cooling system operates only when needed, reducing noise, energy use and the amount of contaminants pulled through machine.

Lightweight aerospace-grade aluminum case
Offers protection with the benefit of reduced weight.

New durability standard for field construction.
Designed and built to withstand the harshest field environments.

Tweco®-style weld disconnects
Provide high-quality weld cable connections.

Jobsite mobility is made easy
Small, compact design and Auto-Line technology.

Process selector switch
Reduces the number of control setup combi nations without reducing any features.

Adaptive Hot Start™
Makes starting stick electrodes easy without creating an inclusion.

Infinite arc control
Available in the stick and wire modes for easier fine tuning of tough-to-weld materials and out-of-position applications.

Lift-Arc™
Provides arc starting that minimizes contamination of the electrode and without the use of high-frequency.

True multiprocess system
Provides conventional stick, TIG, FCAW, and MIG welding as well as the advanced technologies of RMD® and pulse.

Fleet compatibility.
ArcReach-equipped power sources and wire feeders work with non-ArcReach equipment; however, the complete ArcReach benefit is only realized with the ArcReach system.
