230 VAC: 5 – 150 A (DC TIG)
20 – 150 A (DC Stick)

Input Power

Max. Open-Circuit Voltage 90

Single-Phase Power

Net Weight 13.7 lb. (6.2 kg)

Pulse. Pulsing can increase puddle
agitation, arc stability and travel speeds
while reducing heat input and distortion.

Allows for any input voltage hookup
(115–230 V) with no manual linking,
providing convenience in any job
setting. Ideal solution for dirty or
unreliable power.

High frequency for non-contact arc
initiation that reduces tungsten and
material contamination.
Selectable trigger configuration
allows the operator to choose
standard or 2T trigger method to meet
the application.
Single amperage range allows
operator to accurately set amperage on
both 115 or 230-volt primary power.

Multi-Voltage Plug (MVP™) allows
for connection to 115 or 230-volt
receptacles without tools by choosing
the plug that fits the receptacle and
connecting it to the power cord.
Portable in the shop or at the
job site — at 13.7 pounds, the
shoulder strap allows the end
user to easily move from location
to location.
Lift-Arc start provides TIG arc
initiation without the use of high
frequency.
™

Full function remote control for
precise amperage control for critical
welds on thin materials (6-pin
fingertip or foot control available.)
Thermal overload protection
with indicator light helps prevent
machine damage if the duty cycle
is exceeded or airflow is blocked.

Inverter-based, DC power source has
a simple-to-use operator interface
providing only the necessary controls
in a compact machine.
Hot Start™ adaptive control provides
positive arc starts without sticking.

Best-in-class Stick arc characteristics for those demanding jobs.
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.
Power Factor Corrected (PFC) for
optimum performance especially
on 115 volt — reduces nuisance
breaker tripping.
Fan-On-Demand™ power source
cooling system operates only when
needed, reducing noise, energy use
and the amount of contaminants
pulled through the machine.

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

Power source is warranted for 3 years, parts and labor.
Original main power rectified parts are warranted for 5 years.
