Miller XMT 350 MPa

Auto-Line™ Power Management

Automatically compensates for various input Voltage. Suits jobsite and generator power. Keeps welding output constant even if input power varies by +/- 10%.

Dinse or Tweco Style Weld Disconnects

Provides high-quality weld cable connections.


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


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

Wind Tunnel Technology™

Protects electrical components and PC boards from contamination.

Inverter Arc Control Technology

Provides greater puddle control for superior 6010 Stick electrode performance, and outstanding MIG weld performance.

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.

Process Selector Switch

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

Large, Dual Digital Meters

Easy to view and can be pre-set.

Built-In Pulsed MIG Programs With Synergic Capability

VRD TO CAT C AS 1674.2
