[SIZE=4]MAXSTAR 150 STH
Best of Class - provides maxium portability and performance in the most compact TIG/Stick package in the industry. Dependability and performance all in one machine.

Portable in the shop or at the job site - at 13.7 lb the shoulder strap allows the operator to easily move from location to location.

Auto-Line™ Power Management technology circuitry automatically connects to 115 - 230 VAC, single-phase power without removing the cover to relink the power source.

Low OCV Stick returns OCV to 13 volts when machine is not in use.

Adaptive Hot Start for stick arc starts prevents electrode sticking.

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

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.

Thermal overload protection with indicator lights helps prevent machine damage if the duty cycle is exceeded or airflow is blocked.

HF (High Frequency) start for non-contact TIG arc starts (STH model only).

Built-in pulsing -select from four fixed-pulse frequencies (STH model only).

Fan-On-Demand™
Internal power source cooling system that only works when needed, keeping internal components cleaner.

Lift-Arc™
Simply touch the tungsten to the work piece…lift…and the arc is initiated instantly and automatically without the use of high frequency.

Wind Tunnel Technology™
Internal air flow that protects electrical components and PC boards from dirt, dust, debris... greatly improving reliability.

LVC™ Line Voltage Compensation
Keeps output of the power source constant regardless of fluctuation in input power ± 10%.


Adaptive Hot Start™ for Stick
Automatically increases output amperage at the start of a weld should the start require it and prevents the electrode from sticking and creating an inclusion.

Low OCV Stick
A built-in circuit that reduces the open-circuit voltage (OCV) to 13 volts when the welding power source is not in use, therefore eliminating the need for add-on voltage reducers.

Automatically conects the machine to a broad range of primary single- and three-phase, 50 and 60 Hz input voltages without manually linking. Also compensates for voltage spikes and drops within the entire range. Delivering consistent output - All done without removing the covers to relink.
