The balance control is adjustable to provide additional oxide removal (more cleaning) or less cleaning based on the condition of the material being welded. See pg 2 for more information on this feature.

Syncro Startallows the choice of Soft, Standard or Hot TIG starts based on the application, lead lengths and tungsten size.

Dual inline high-frequency points provide intense high frequency for arc starting and stabilization. Internal machine components are protected from HF interference with additional grounding and filtering for extended product life.

Digital welding meters display both amperage and voltage for viewing of the actual and preset values for greater accuracy and repeatability in your welding procedure.

Last procedure recall simplifies changing your Syncrowave back and forth from aluminum TIG to stainless TIG to stick welding. One switch makes all the control panel changes.

Power source is warranted for 3 years, parts and labor.

Original main power rectifier parts are warranted for 5 years.

350 LX, 250 DX specifications

Miller Electric has long been recognized as a leader in the welding equipment industry, and their Miller Electric 250 DX and 350 LX models showcase the superior technology and innovation that the brand is known for. These machines are designed to provide high-quality welding performance and user-friendly convenience, catering to both professional welders and hobbyists alike.

The Miller Electric 250 DX is a versatile DC multi-process welder capable of TIG, MIG, stick, and even flux-cored welding. One of its standout features is the Auto-Set function, which simplifies the welding setup process. By automatically adjusting the machine settings based on the material thickness and type, this feature allows users to spend less time on preparations and more time welding. Additionally, the 250 DX's wide range of output power—from 5 to 250 amps—makes it ideal for diverse applications, from thin sheet metal to heavy-duty fabrication.

On the other hand, the Miller Electric 350 LX takes versatility a step further. With the capacity to handle both AC and DC welding, it is perfect for a variety of applications, including aluminum welding, which often requires AC output. The 350 LX also incorporates advanced technologies such as Auto-Set Elite, providing precise, easy-to-navigate control over parameters for both novice and experienced welders. This not only enhances the user experience but ensures consistent and high-quality welds every time.

Both models feature the i-TIG function, which allows for easy toggling between different welding processes without needing to modify the setup extensively. Furthermore, with sturdy construction and portable design, these machines are built to withstand the rigors of job site environments while being easily transportable.

The additional presence of a built-in temperature control system helps prevent overheating, ensuring durability and reliability. Miller's commitment to safety is evident in both models, which include advanced features like automatic shut-off and fault detection.

In summary, the Miller Electric 250 DX and 350 LX are two exceptional welding machines that combine user-friendly functions, cutting-edge technology, and robust design. Whether for professional or personal use, these welders promise to deliver outstanding performance, ensuring that they meet the diverse needs of modern welders. Both models stand as a testament to Miller Electric's dedication to quality and innovation in the welding industry.
