The Power of Blue.
14-pin receptacle provides quick,
direct connection to Miller 14-pin
wire feeders and accessories.
DC multiprocess capability
provides versatility and outstanding
arc performance in SAW
115 V duplex receptacle provides
15 amps of auxiliary power.
(Submerged Arc) and CC (Stick,
Carbon Arc Gouging).
Remote on/off capabilities allow
operator to turn power source
on/off from a distance.
Internal digital voltage control
(DVC) enables operator to preset
weld voltage in the CV mode before
striking an arc.
Remote voltage control allows
operator to change voltage from
SAW Control.
Built-in arc control lets you get in
tight without sticking the electrode.
An electrode compensation circuit
ensures consistent arc control
performance regardless of the
electrode size.
Power efficient for exceptional value
and return on your investment.
Fan-On-Demand™ operates only
when needed reducing noise, power
consumption, and the amount of
airborne contaminants pulled
through the machine.
Hot Start™ makes it easier to start
difficult-to-start Stick electrodes
such as E-6010 and E-7018.
Line voltage compensation
ensures consistent weld
performance by keeping output
power constant even if primary
input power varies by 10%.
Enclosed circuit boards provide
additional protection from
contaminants resulting in longer
service life.
Sub Arc DC 650
Power cord strain relief provided
for your convenience at installation.
Thermal overload protection light indicates
power shutdown. Helps prevent machine damage
if the duty cycle is exceeded or airflow is blocked.
Simple control panel features single
range amperage/voltage adjustment.
Provides easy, efficient operation.
Digital voltmeter and ammeter are
easy to read, even at 30 ft (9.2 m).
Power source is warranted for 3 years, parts and labor.
Original main power rectified parts are warranted for 5 years.
