XMT® 350 FieldPro™ with Polarity Reversing, Tweco®

907731
Outdated equipment threatens your productivity, profitability and safety. XMT® 350 FieldPro™ with Polarity Reversing Systems have industry leading technology with no need to manually swap polarity or cables/hoses between processes. The 'Quick-Select' technology automatically selects the welding process, the correct polarity, cable outputs and welding parameters. Optimized Stick and TIG arc performance is specifically designed for open root pipe welding while reducing training time and increasing quality.

Features

ArcReach® Technology
ArcReach capabilities increase jobsite productivity and efficiency by eliminating the time spent tracing weld cables hundreds of feet back to the power source because weld operators can make voltage adjustments at the ArcReach wire feeder or remote.   Learn More
Cable Length Compensation
Cable Length Compensation (CLC™) ensures that the voltage a weld operator sets is the voltage they get by automatically adjusting voltage based on weld cable length, even hundreds of feet away from the power source.
Auto-Line™ Technology
Allows hookup to either single-phase or three-phase primary input voltage, 208-600 volts dependent on the machine, with no manual linking, providing convenience in any job setting. An ideal solution for dirty or unreliable input power.   Learn More
Exceptional Arc Performance
XMT 350 FieldPro systems maximize weld quality, reduce training time and minimize weld defects even while using weld cables that are hundreds of feet long.
Increased Uptime
XMT 350 FieldPro welders and ArcReach accessories have been extensively field-proven and deliver the performance you need with ruggedly constructed internal components and Wind Tunnel Technology™.
Improved Jobsite Safety
The chances of slip, trip and fall injuries are decreased because ArcReach technology allows weld operators to make parameter changes at the wire feeder or remote instead of having to travel through multistory and cluttered jobsites back to the power source.
Adjust While Welding
Weld operators have more control and can Adjust While Welding (AWW™) to make fast, easy weld parameter changes at the wire feeder or remote — even while the arc is on. Only Miller offers this advanced solution.   Learn More
Auto-Process Select™
Automatically sets the power source to the correct weld process based on the polarity applied to the weld accessory and decreases the chance of an incorrect weld process.
ArcReach Heater Compatibility
Take charge of your field preheat and bakeout applications up to 600 degrees Fahrenheit (315°C). This system uses induction heating to generate heat in workpieces, so welders can do their own preheating quickly and safely. A part of the ArcReach technology platform, the ArcReach Heater is an accessory for select ArcReach welding power sources.   Learn More
Control Panel Lock Out
Inadvertent parameter changes by other jobsite workers can be avoided because connecting an ArcReach accessory to the power source automatically locks out the power source’s panel controls.
Maximum Fleet Compatibility
Maximize fleet compatibility and get the benefits of ArcReach when you pair XMT 350 FieldPro welders and ArcReach feeders with other ArcReach compatible products.
