XMT

Series

Multiprocess Welding

Power Source

Issued June 2004 • Index No. DC/18.8

Lightweight, aerospace-grade aluminum case

offers protection with the benefit of reduced weight.

Lift-Arc

™

allows TIG starting without the use of

high-frequency. Starts the arc without contaminating

the weld with tungsten.

Adaptive Hot Start

™

increases the output amperage

at the start of a weld if necessary, eliminating

electrode sticking.

Inverter arc control technology provides greater

puddle control for superior 6010 Stick electrode

performance.

Fan-On-Demand

™

cooling system operates only

when needed, reducing noise, energy use and the

amount of contaminants pulled through machine.

The Power of Blue

115 VAC auxiliary power provides 10 amps of

circuit-breaker-protected power for water

circulators, etc. Standard on XMT 456, optional on

XMT 304 and XMT 350 CC/CV models only.

Wind Tunnel Technology

™

protects electrical

components and PC boards from contamination.

Line voltage compensation keeps power constant

even if power input varies by ±10%.

Process selector switch reduces the number of

control setup combinations without reducing

any features.

Large, dual digital meters are easy to view and are

presettable to ease setting weld output.

Pulsed MIG capabilities with optional Optima

control reduces spatter and distortion, allows better

out-of-position puddle control, and provides

potential reduction of fume particle emission.

NEW! XMT 350 provides more welding

output with superior electrical efficiency

and an amazing .95 power factor!
