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Outdated equipment threatens your productivity, profitability and safety.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 (available only with XMT 350 FieldPro Systems).   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.
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.
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 (available only with XMT 350 FieldPro Systems).   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.
Auto-Process Select™
Decrease the chance of an incorrect weld process being used because Auto-Process Select automatically sets the power source to the correct weld process based on the polarity applied to the weld accessory.
Auto-Line™ Technology
Work in more places with Auto-Line technology which automatically calibrates the power source to operate properly when connected to any primary input voltage ranging from 208-575 volts, single- or three-phase, 50 or 60 Hz — with no manual linking required.   Learn More

Game-Changing Welding Technologies Stop You From Wasting Hours Every Day
When welding operators must stop welding to walk to the power source to make adjustments this lost time adds up, totaling significant labor costs that could be better spent on value-added tasks. This productivity loss is especially painful for operations that already struggle to find skilled labor. These stops and starts can also impact weld quality and operator safety.
