1 Jog/Purge Push Button

Pressing the Jog/Purge switch al- lows the operator to jog wire without energizing the weld power or gas valve circuit.

•Jog speed can be adjusted with the Wire Speed control when the unit is jogging wire. If equipped with meters, the unit displays jog speed while the unit is being jogged.

•Pressing the Jog/Purge button also allows the operator to purge gas lines before welding and to preset gas pressure at the regu- lator.

2 Trigger Hold Switch

Trigger hold allows the operator to weld without holding the gun trigger.

•To use the trigger hold function, place the trigger hold switch in the On position.

•The operator must hold the trig- ger for a minimum of 2 seconds, but not longer than 6 seconds be- fore releasing it. Welding will con- tinue when the trigger is released.

•To stop welding, press the trigger again.

S-75S, S-75D specifications

Miller Electric is renowned for its cutting-edge welding and fabrication technology, and the S-75D and S-75S models stand out in their lineup, highlighting excellence in performance and versatility. Designed for both professional welders and industrial applications, these power sources are equipped to handle a variety of welding processes, from MIG to Flux-Core welding.

The Miller Electric S-75D is characterized by its robust construction and advanced technologies. One of its main features is the Auto-Set function, which simplifies the setup process by automatically adjusting the parameters based on the material thickness and wire size. This ensures optimal welding performance, providing welders with confidence in their work. Additionally, the S-75D is equipped with a powerful inverter design, offering increased efficiency and portability. Weighing significantly less than traditional transformer-based units, the S-75D allows for easier transportation to job sites without compromising on power.

On the other hand, the S-75S model incorporates several user-centric enhancements. With a focus on operational ease, it includes a large, intuitive digital display that provides real-time feedback on welding parameters. This feature allows for quick adjustments, ensuring that welders can maintain control over their projects. Furthermore, the S-75S boasts a duty cycle of up to 60%, making it ideal for heavy industrial applications where continuous operation is critical.

Both models share several key technologies that enhance their performance. The Wind Tunnel Technology, for instance, provides superior cooling capabilities, protecting internal components from dust and debris, which prolongs the life of the machine. Additionally, the Power Feed system supports large spools of wire, reducing the frequency of spool changes during long projects.

In terms of characteristics, the S-75D and S-75S are designed with durability in mind. They feature rugged chassis construction and high-quality components that withstand harsh working environments. Furthermore, both machines are equipped to operate in various settings, including fabrication shops, construction sites, and maintenance applications.

In summary, the Miller Electric S-75D and S-75S models represent the pinnacle of welding equipment innovation. With features like Auto-Set, robust duty cycles, intuitive displays, and advanced cooling technologies, they are engineered to meet the demands of skilled welders who seek efficiency, reliability, and high-quality performance in their work. These power sources are ideal for tackling complex welding tasks while ensuring user-friendly operation and durability in any environment.
