NT 456

Multiprocess Welding

Power Source

Issued May 2007 • Index No. DC/19.7

Lift-Arc

™

allows TIG starting without

the use of high-frequency. Starts the

arc without contaminating the weld

with tungsten.

Internal digital voltage control (DVC)

enables operator to preset weld voltage

in the CV mode before striking an arc.

Optional fan settings: fan can be set

to run continuously or set to use

Fan-On-Demand

™

(factory setting)

which operates only when needed.

This feature reduces noise, energy

use and the amount of contaminants

pulled through machine.

Pulse program select switch offers ten

different programs: .035/.045 in steel,

.035/.045 in stainless steel, .035/.045 in

Inconel, .035 in CuNi, .035 in NiCu,

.035 and 3/64 in aluminum.

The Power of Blue

Power source is warranted for 3 years, parts and labor.

Original main power rectified parts are warranted for 5 years.

Quick

Specs

Line voltage compensation keeps power

constant even if power input varies by ±10%.

Extended base rails add an additional 2-1/2 in

to the height to protect internal components

from harsh environments.

Thermal overload protection helps

prevent machine damage if the duty cycle

is exceeded or airflow is restricted.

Inductance/Dig Control to optimize

MIG/Stick arc performance.

115 VAC duplex receptacle provides

15 amps of auxiliary power.

Remote control capability allows

operator to make changes at the

welding location rather than at the

power source.

14-pin receptacle provides quick,

direct connections to Miller 14-pin

wire feeders and accessories.

Excellent power efficiency for

exceptional value and return on

your investment.

Internal diagnostic help codes

indicate power source problems,

reduce downtime, and aid in

service repairs.

Power cord strain relief is provided

for convenience at installation.

Enhanced environmental protection:

all critical components such as PC

boards, IGBT’s and capacitors are

housed in protective enclosures.

Process selector switch is operator

friendly, reducing the number of

control setup combinations without

reducing any features.
