DC multiprocess capability
provides versatility and
outstanding arc performance
in CV (MIG) and CC (Stick,
TIG, CAC-A).

MillerWelds.com/equiptoweld or
see the Stationary and MIGRunner™
Packages (see page 3).
Inductance/DIG control with
presettable digital display to
optimize MIG/Stick
performance.
Fan-On-Demand™ which operates
only when needed. This feature
reduces noise, energy use and the
amount of contaminants pulled
through machine.
Internal digital voltage control
(DVC) enables operator to
preset weld voltage in the
CV mode prior to welding.
Line voltage compensation
ensures consistent weld
performance by keeping
output power constant even if
primary input power varies by
±10 percent.
Lift-Arc™ allows TIG starting without
the use of high-frequency. Starts the
arc without contaminating the weld
with tungsten.
Power efficient for exceptional
value and return on your
investment.
Process selector switch automatically
sets contactor requirements, eliminating confusion caused by several
switch combinations and making this
machine very “operator-friendly.”
115 VAC duplex receptacle
provides 15 amps of auxiliary
power.
Enhanced environmental protection.
All critical components housed in
protective enclosures.
Thermal overload protection
helps prevent machine damage
if the duty cycle is exceeded or
airflow is blocked.
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.
Dimension™ NT 450 MIGRunner ™ Package shown.
Power source is warranted for 3 years, parts and labor.
Original main power rectified parts are warranted for 5 years.
