The Power of Blue
DC multiprocess capability
provides versatility and outstanding
arc performance in SAW
(Submerged Arc) and CC (Stick,
Carbon Arc Gouging).
Internal digital voltage control
(DVC) enables operator to preset
weld voltage in the CV mode before
striking an arc.
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.
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%.
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).
Processes
Submerged Arc (SAW)
Air Carbon Arc (CAC-A)

Power Source

14-pin receptacle provides quick,
direct connection to Miller 14-pin
wire feeders and accessories.
115 V duplex receptacle provides
15 amps of auxiliary power.
Remote on/off capabilities allow
operator to turn power source
on/off from a distance.
Remote voltage control allows
operator to change voltage from
SAW Control.
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.
Enclosed circuit boards provide
additional protection from
contaminants resulting in longer
service life.
Power cord strain relief provided
for your convenience at installation.
