TIG/Stick Welding

Power Source

Issued February 2008 • Index No. DC/27.1

The Power of Blue®.

Portable in the shop or at the job
site — at 13.7 lb the shoulder strap
allows the end user to easily move
from location to location.

Full function remote control for
precise amperage control for critical
welds on thin materials (6-pin fingertip
or foot control available.)

Fan-On-Demand

™

power source
cooling system operates only when
needed, reducing noise, energy use
and the amount of contaminants
pulled through the machine.

Inverter-based, DC power source has
a simple-to-use operator interface
providing only the necessary
controls in a compact machine.

Lift-Arc

™

start provides TIG arc starting

without the use of high frequency.

Thermal overload protection with
indicator light helps prevent machine

damage if the duty cycle is exceeded
or airflow is blocked.

Single amperage range allows
operator to accurately set amperage
on both 115 or 230 V primary power.

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

Original main power rectifiers are warranted for 5 years.

Adaptive Hot Start

™

for Stick arc

starts automatically increases the

output amperage at the start of a
weld should the start require it.
Prevents the electrode from
sticking and creating an inclusion.

Low OCV Stick is a simple design
that reduces the open-circuit
voltage to 12–16 V when the
welding power source is not in use.
This circuit design is now built into
the Maxstar 150 STL eliminating
the need for add-on voltage reducers.

Built-in gas solenoid eliminates the
need for bulky torch with a gas valve.

Auto-Line

™

provides state-of-the-art
flexibility to the end user. The Auto­Line circuitry automatically connects
to 115–230 VAC, single-phase power
without removing the covers to relink
the power source. No longer is there
a concern if you have the correct
machine for the shop or job site.

Miller’s exclusive

multi-voltage plug
(MVP

™

) allows

connection to 115
or 230 V receptacles

without tools —
choose the plug that fits the receptacle
and connect it to the power cord.
