Miller Maxstar 161 STL Stick Welder

What is the amperage range of the Maxstar 161 STL on 120V vs 240V?

On 120V, the amperage range is 5–130A for DC TIG and 20–90A for DC Stick. On 240V, the range extends to 5–160A for DC TIG and 20–160A for DC Stick. This single amperage range allows the operator to accurately set amperage on both 120- or 240-volt primary power. (Page 1)

What is the duty cycle of the Maxstar 161 STL when running at 160 amps on 240V?

At 160A on 240V, the duty cycle is 20% for both TIG and Stick modes. For TIG at 160A, the rated output is 16.4 VDC, and for Stick at 160A, the rated output is 26.4 VDC. Exceeding the duty cycle may trigger thermal overload protection to prevent machine damage. (Page 2)

How much does the Maxstar 161 STL weigh and what are its dimensions?

The Maxstar 161 STL weighs 13 lb. (5.9 kg) and measures 10.3 in. (262 mm) H x 5.6 in. (142 mm) W x 13.5 in. (343 mm) D. Its lightweight design and included handle/shoulder strap make it portable for both shop and job site use. (Page 2)

What is the maximum open-circuit voltage (OCV) of the Maxstar 161 STL?

The maximum open-circuit voltage is 48 VDC. However, the Low OCV Stick feature reduces open-circuit voltage to 12–16 volts when the welding power source is not in use, eliminating the need for add-on voltage reducers. (Page 2)

What controls and receptacles are on the Maxstar 161 STL control panel?

The control panel includes a Power Switch, Menu Button, Positive Weld Output Receptacle, Remote Receptacle, Ready Light, Amperage Adjustment Control, and Negative Weld Output Receptacle. The digital meter allows for more precise control when presetting or monitoring welding amperage. (Page 2)

What is included in the Maxstar 161 STL Standard Package (907710)?

The Standard Package includes the Maxstar 161 STL power source, 6.5 ft. (2 m) 120-volt and 240-volt power cords, a stick electrode holder with 13 ft. (4 m) cable and 25 mm Dinse-style connector, a work clamp with 10 ft. (3 m) cable and 25 mm Dinse-style connector, one air-cooled TIG torch connector (195234), and a handle/shoulder strap. (Page 3)
