Power source is warranted for 3 years, parts and labor.
Original main power rectified parts are warranted for 5 years.
Selectable trigger configuration allows
the operator to choose standard or 2T
trigger method to meet the application.
Built-in pulsing capabilities allow the
operator to select from four fixed pulse
frequencies to satisfy the application.
HF start for non-contact arc starting
that eliminates tungsten or material
contamination.
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.
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 volts when the
welding power source is not in use.
This circuit design is now built into
the Maxstar 150 STH 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 Auto-
Line 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.
