XMT

Series

Multiprocess Welding

Power Source

Issued August 2002 • Index No. DC/18.8

Lightweight, aerospace-grade aluminum case offers

protection with the benefit of reduced weight.

XMT 304 MIGRunner

™

power-efficient package

comes complete in one box. See page 7 for details.

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 (optional on XMT 304) provides

10 amps of circuit-breaker-protected power for water

circulators, etc.

Wind Tunnel Technology

™

protects

electrical components and PC boards

from contamination.

Specs

XMT 456 CC/CV only

Primary voltage display shows what

primary voltage the power source is

set for without removing the side

panels. Saves time and assures you

that the power source has been

correctly set for available input voltage.

Unique case design helps protect

internal components from dirt and dust.

To connect input power cord and/or

set unit up for correct input power,

remove the easy-to-handle panel

(1/3 case). The remaining two-thirds of

the case never needs to be removed!

Optional remote on/off provides

ability to turn power source on or off

when it is located away from your work.

XMT 304 only

Auto-Link

circuit automatically links

the power source to primary voltage

being applied (230/460 or 460/575 VAC,

single- or three-phase).

Ultra-tough, polycarbonate-blended

cover for control panel protects front

controls from damage.

International-style weld disconnects

provide high-quality weld cable

connections. (Two connectors supplied

with each unit.)

XMT 304

New!

Line voltage compensation keeps

power constant even if power input

varies by ±10%.

Process selector switch

reduces the number of

control setup combi-

nations 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.
