907710 - Miller Maxstar 161 STL DC TIG/Stick Inverter Welder

Compact Industrial DC TIG and Stick Welding Solution

The Miller Maxstar 161 STL is a premier choice for industrial professionals requiring a lightweight, highly portable welding power source without compromising on arc quality. Weighing in at just 13 pounds (5.9 kg), this inverter-based machine is engineered for mobility, making it ideal for maintenance, repair, and field operations across diverse sectors such as aerospace, food and beverage, and shipboard installation. The unit features Miller's proprietary Auto-Line Power Management Technology, which allows for seamless connection to either 120V or 240V single-phase power without the need for manual linking or tools, ensuring operational flexibility in environments with varying power availability.

Designed for precision and reliability, the Maxstar 161 STL offers a TIG amperage range of 5 to 160 amps, enabling users to weld materials as thin as 0.020 inches. The Lift-Arc start method provides smooth TIG arc initiation without the electromagnetic interference associated with high-frequency starts, which is critical in sensitive electronic environments. For Stick welding applications, the machine excels with difficult electrodes; its 6010 capability ensures superior arc performance, while Adaptive Hot Start technology eliminates the frustration of sticky electrodes during ignition. Furthermore, the integrated Stick-Stuck feature enhances safety and consumable life by automatically cutting output if the electrode fuses to the workpiece.

This Standard Package (907710) is equipped with essential components to get started immediately with Stick welding, including a high-quality electrode holder and work clamp with Dinse-style connectors. The built-in gas solenoid simplifies TIG setups by removing the need for a torch-mounted gas valve, streamlining the torch assembly for better ergonomics. With a robust 20% duty cycle at 160 amps (240V), the Maxstar 161 STL delivers consistent industrial-grade performance in a compact footprint.
