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.

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.

Lift-Arc™ start provides TIG arc starting without the use of high frequency.

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

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.

TIG/Stick Package (#907 135-01-7) comes complete with:

Maxstar 150 STL

10 ft (3 m) MVP™ power cord

MVP™ plugs 5-15P (115 V, 15 A) and 6-50P (230 V, 50 A)

X-CASE™ provides protection in transport and storage

Remote fingertip control

Weldcraft® WP1712RD125 TIG torch with adapter

13 ft (4 m) Stick electrode holder with 25 mm Dinse connector

10 ft (3 m) work clamp with 25 mm Dinse connector

Smith® regulator with gas hose AK-2C accessory kit

Shoulder strap

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

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

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

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.

Best in class Stick arc characteristics for those demanding jobs.

Power Factor Corrected (PFC) for optimum performance especially on 115 V — 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.
