ArcReach welding technology minimises the non-value added time spent walking to and from the power source - and maximises arc-on time, weld quality and job site safety.

Superior Arc Performance

The optimised stick and TIG performance specifically meets the needs of open root pipe welding and helps reduce training time and increases quality. Starts maintain root opening and prepared edge and stop limit arc marks outside of the heat-affected zone.

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.
*Only available when connected to an XMT 350 FieldPro power source.

Regulated Metal Deposition (RMD™) & Pulse Welding*

Enables operators to use these advanced processes in the field for faster, more efficient welds.

*Available with ArcReach Smart Feeder only

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.

*Only available when connected to an XMT 350 FieldPro power source.

Auto-line™ Power Management

Automatically compensates for various input Voltage. Suits job site and generator power. Keeps welding output constant even if input power varies by ±10%. Single or 3 phase.

Wind Tunnel Technology™

Protects electrical components and PC boards from contamination.


The cooling system operates only when needed, reducing noise, energy use and the number of contaminants pulled through the machine.

New Durability Standard for Field Construction

Designed and built to withstand the harshest field environments.


Allows TIG starting without the use of high-frequency. Starts the arc without contaminating the weld with tungsten.

Dinse Style Weld Disconnects

Provides high-quality weld cable connections.

Adaptive Hot Start™

Increases the output Amperage at the start of a weld if necessary, eliminating electrode sticking.

Lightweight, Aerospace-Grade Aluminium Case

Offers heavy-duty protection with the benefit of reduced weight.


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

Jobsite Mobility

Made easy with a small, compact design and Auto-Line technology.

Process Selector Switch

Reduces the number of control setup combinations without reducing any features.

True Multi-Process System

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

Infinite Arc Control

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

Fleet Compatibility

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