  • Light industrial products are suitable for the home hobbyist or occasional user. They are designed to be easy to operate, are affordably priced and typically have a 20% duty cycle and rated output of 230 amps or lower.
  • Auto-line: The Auto-Line circuit boosts primary power to a higher, constant voltage. Even if incoming voltage varies widely, the circuit ensures a rock-steady welding or cutting arc.
  • 1 Phase: Unit requires single-phase input power
  • DC: Unit supplies direct current weld output
  • CC: Unit supplies constant-current weld output
  • Auto-Line 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.
  • 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
  • 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
  • Digital meter for more precise control when presetting or monitoring welding amperage
  • Simple-to-use operator interface providing only the necessary controls in a compact machine
  • Lift-Arc™ provides TIG arc initiation without the use of high frequency
  • Built-in gas solenoid eliminates the need for a 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)
  • Selectable trigger configuration allows the operator to choose standard or 2T trigger method to meet the application
  • •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 161 eliminating the need for add-on voltage reducers.
  • Hot Start™ adaptive control provides positive arc starts without sticking
  • 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
  • Additional STH model features: •Pro-Set™ eliminates the guesswork when setting weld parameters. Use Pro-Set when you want the speed, convenience and confidence of preset controls. Simply select the feature and adjust until Pro-Set appears on the display. •High-frequency for non-contact arc initiation that reduces tungsten and material contamination •Pulse. Pulsing can increase puddle agitation, arc stability and travel speeds while reducing heat input and distortion.
  • Processes: •Stick (SMAW) •Lift-Arc™ TIG (GTAW) •High-frequency TIG (GTAW)* •Pulsed TIG (GTAW-P)* *STH model only
  • Comes Complete with: Maxstar 161 power source, 6.5 ft. (2 m) 120-volt and 240-volt power cords, 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, One air-cooled TIG torch connector, Handle/shoulder strap, and Quick-reference guide.
  • TIG/Stick Package Comes Complete with: Maxstar 161 power source, 6.5 ft. (2 m) 120-volt and 240-volt power cords, X-CASE™—provides protection in transport and storage, Remote fingertip control, Weldcraft™ A-150 12.5 ft. (3.8 m) TIG torch with connector, Stick electrode holder with 13 ft. (4 m) cable and 25 mm Dinse-sty
