Power Source
Amperage Range 120 V: 5–130 A (DC TIG)
Input Power
120–240 V, 1-phase power
20–90 A (DC stick)
240 V: 5–160 A (DC TIG)
20–160 A (DC stick)
Max. Open-Circuit Voltage 48
Net Weight 13 lb. (5.9 kg)
Single amperage range
allows operator to accurately
set amperage on both 120- or
240-volt primary power.
Allows for any input voltage hookup
(120–240 V) with no manual linking,
providing convenience in any job
setting. Ideal solution for dirty or
unreliable power.
Inverter-based, DC power
source has a simple-to-use
operator interface providing
only the necessary controls in
a compact machine.
Portable in the shop or at the
job site — at 13 pounds, the
handle/shoulder strap allows the
end user to easily move from
location to location.
Hot Start™ adaptive control
provides positive arc starts
without sticking.
Lift-Arc™ provides TIG arc initiation
without the use of high frequency.
Low OCV stick is a simple
design that reduces the opencircuit voltage to 12–16 volts
when the welding power source
is not in use. This circuit design
is now built into the Maxstar
161 STL eliminating the need
for add-on voltage reducers.
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.
Thermal overload protection
helps prevent machine damage if
the duty cycle is exceeded or airflow
is blocked.
Built-in gas solenoid eliminates
the need for a bulky torch with a
gas valve.
Digital meter for more precise
control when presetting or
monitoring welding amperage.
TIG/Stick Package with Remote Fingertip Control (907710002)
comes complete with:
Maxstar 161 STL power source
6.5 ft. (2 m) 120-volt and 240-volt power cords
X-CASE™ — provides protection in transport and storage
RCCS-6M remote fingertip control (195184)
Weldcraft™ A-150 (WP-17) 12.5 ft. (3.8 m) TIG torch with connector
Stick electrode holder with 13 ft. (4 m) cable and 25 mm
Dinse-style connector
Work clamp with 10 ft. (3 m) cable and 25 mm Dinse-style connector
Flow gauge regulator with gas hose
AK2C accessory kit with short back cap, nozzles, collets, collet bodies,
and 2% ceriated tungsten electrodes (.040, 1/16, and 3/32 in.)
Handle/shoulder strap
Power factor corrected (PFC)
for optimum performance
especially on 120 volts —
reduces nuisance breaker
tripping.
Stick-Stuck detects if the
electrode is stuck to the part
and turns the welding output
off to safely and easily remove
the electrode. Menu selectable.
Superior stick arc performance
even on the difficult-to-run
electrodes like E6010.
Power source is warranted for three years, parts and labor.
Original main power rectified parts are warranted for five years.
