Compact Design- Weighing in at 13 lbs. and featuring a convenient handle/shoulder strap, this little inverter-based machine can be taken from location to location.
Use on 120 and 140 Volt Input Power – Separate 120 and 240 volt power cords disconnect from the rear panel of the machine without the use of any tools to allow you to use common 120 and 240 volt power receptacles.
Low Power Draw – By utilizing an inverter-based power source in the Maxstar® 161, superior arc starts and excellent weld puddle control are provided in both the TIG and Stick settings – all in a small, lightweight package.
6010 Stick Electrode Capability – Superior Stick arc performance even on the difficult-to-run electrodes like E6010.
No More “Sticky” Electrodes – With Miller’s Adaptive Hot Start™ technology, you no longer have to worry about those difficult-to-strike electrodes.
Conserve your Electrodes – With the Stick-Stuck feature, the machine detects if the electrode is stuck to the part and turns the welding output off to safely and easily remove the electrode.
No Need for a Gas Valve on your TIG Torch – With a built-in gas solenoid, the Maxstar® 161 eliminates the need for a bulky TIG torch with a gas valve
5 Amp TIG Capacity – Allows users to weld thinner materials than other machines in this category.
Easy-to-Use – 1. Turn power on. 2. Select process: High-Frequency TIG, Lift-Arc™ TIG, Stick, or 6010 Stick. Set amperage. 3. Then weld! It’s as easy as 1, 2, 3.
