XMT

400 CC/CV

Multiprocess Welding

Power Source

Issued January 2004 • Index No. DCX/18.92

Lightweight, durable aluminum

case offers protection with the

benefit of reduced weight.

Weld cable connections are made easy

with high-quality international-style

quick disconnects (two connectors

supplied with each unit).

Lift-Arc

™

allows TIG starting without

the use of high-frequency. Starts the

arc without contaminating the weld

with tungsten.

Adaptive Hot Start

™

for Stick arc starts

automatically increases the output

amperage at the start of a weld if

necessary, eliminating electrode sticking.

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

Wind Tunnel Technology

™

protects

electrical components and PC boards

from contamination, significantly

improving reliability.

Specs

New!

Line voltage compensation keeps

power constant even if power input

varies by ±10%.

Enhanced low-end performance for stainless steel and

thin-metal applications.

Process selector switch reduces the

number of control setup combinations

without reducing any features. The

operator can make quick and easy

changes to the XMT 400 when

changing processes.

Superior 6010 stick electrode

performance with inverter arc

control technology provides the

XMT 400 the puddle control

demanded especially by the pipe

welding industry.

Dual digital meters display both

volts and amps for quick and easy

viewing by operator. Meters are

presettable for ease of setting weld

output. Hold function lets the

operator view actual welding output

when the arc is broken.

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.
