NT 450/500

Multiprocess Welding

Power Source

Issued Dec. 2010 • Index No. DC/19.5

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.

Fan-On-Demand

™

which operates

only when needed. This feature

reduces noise, energy use and the

amount of contaminants pulled

through machine.

The Power of Blue

DC multiprocess capability

provides versatility and

outstanding arc performance

in CV (MIG) and CC (Stick,

TIG, CAC-A).

Processes

MIG (GMAW)

Stick (SMAW)

TIG (GTAW)

Flux Cored (FCAW)

Air Carbon Arc Cutting and Gouging

(CAC-A) (max 5/16 in carbons)

Input Power 3-Phase Power

Rated Output 450 A at 38 VDC,

100% Duty Cycle

Weight 376 lb (171 kg)

Heavy Industrial Applications

Fabrication and Construction

MRO-Maintenance Repair

Pressure Tank/Vessel Fabrication

Pipe Welding and Shipbuilding

Refineries and Foundries

Railcar Manufacturing

Heavy Equipment Manufacturing

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

Original main power rectified parts are warranted for 5 years.

Line voltage compensation

keeps power constant even if

power input varies by ±10%.

Thermal overload protection

helps prevent machine damage

if the duty cycle is exceeded or

airflow is restricted.

Inductance/Dig Control with

pre-settable digital display to

optimize MIG/Stick performance.

115 VAC duplex receptacle

provides 15 amps of

auxiliary power.

Help codes help troubleshoot and

service power source. Help codes

are displayed on the volt/amp

meters. Reduces the time needed to

get the machine back into service.

Excellent power efficiency for

exceptional value and return on

your investment.

Enhanced environmental

protection: all critical components

housed in protective enclosures.

Process selector switch

automatically sets contactor

requirements, eliminating
