3-3. CONTACTOR SWITCH (Figure 3-1)

WARNING: ELECTRIC SHOCK can kill.

• Do not touch live electrical parts.

•Do not touch the weld output terminals when the contactor is energized.

•Do not touch electrode holder (or gun wire) and work clamp at the same time.

If the Remote Control CONTACTOR switch is in the ON position, open-circuit voltage will be present at the out- put terminals whenever the welding power source POWER switch ON button is depressed.

IMPORTANT: Although the term CONTACTOR is used on the nameplate and throughout this manual, the weld output is not switched on or off by a physical secondary contactor; rather, the weld output is controlled by solid- state circuitry in the welding power source.

If contactor control by means of a wire feeder is desired, place the Remote Control CONTACTOR switch in the OFF position. Open-circuit voltage will be present at the weld output terminals whenever the gun switch is closed.

The OFF position is normally used with all wire feeding processes (GMAW, GMAW-P, FCAW, SAW) and the Gas Tungsten Arc Welding (GTAW) process. The ON position is normally used with the Shielded Metal Arc Welding (SMAW) and the Air Carbon Arc (CAC-A) Cut- ting and gouging processes.

3-4. AMMETER SWITCH (Figure 3-1)

The AMMETER switch provides selection of reading PEAK weld amperage or Average (AVG) weld amper- age on the Remote Control digital ammeter.

Normally the AVG switch position is used for reading weld amperage during Gas Metal Arc (GMAW), Flux Cored Arc (FCAW), Submerged Arc (SAW), Shielded Metal Arc (SMAW), Gas Tungsten Arc (GTAW) Welding and Air Carbon Arc (CAC-A) Cutting and gouging pro- cesses.

While welding using the Gas Metal Arc Welding - Pulsed Arc (GMAW-P) process, the AVG switch position is used when display of the average (background and peak) weld amperage is desired. The AMMETER switch can be placed in the PEAK position when display of peak weld amperage is desired.

3-5. AMPS/BKGD CONTROL AND PILOT LIGHT (Figure 3-1)

This control presets weld amperage for constant current applications and background amperage for GMAW-P applications.

When the Mode Selector switch is in the CC position or one of the pulses per second positions, the AMPS/ BKGD pilot light turns on.

This control is disabled when the Mode Selector switch is in the CV position.

Rotating the control clockwise increases amperage.

IMPORTANT: The AMPS/BKGD control can be ad- justed while welding.

RPC-IP specifications

Miller Electric RPC-IP is a revolutionary power distribution and management system designed for advanced welding applications and industrial environments. This innovative equipment aims to enhance productivity, safety, and operational efficiency by optimizing the electrical power supply for multiple welding machines and other high-demand equipment.

One of the main features of the RPC-IP is its intelligent power distribution capabilities. It can manage and distribute power to multiple outputs while monitoring real-time load conditions. This makes it ideal for facilities with variable equipment demands, as it automatically adjusts power distribution to ensure optimal performance without overloads.

The RPC-IP is equipped with cutting-edge technology, including an integrated digital control panel that allows users to monitor and manage power usage intuitively. The control panel features a user-friendly interface that provides real-time data on energy consumption, load distribution, and system health. This level of transparency empowers operators to make informed decisions and minimize downtime.

Another notable characteristic of the RPC-IP is its advanced safety features. The system incorporates overload protection, short-circuit protection, and surge protection, ensuring that both equipment and personnel are safeguarded against power-related hazards. Additionally, the RPC-IP is compliant with stringent industry standards, which further enhances its reliability and user confidence.

Miller Electric has also prioritized connectivity in the RPC-IP design. The system supports remote monitoring and control via cloud-based technologies, enabling operators to access data and manage power distribution from virtually anywhere. This feature is particularly beneficial for multi-site operations where consistent oversight and management are crucial.

The RPC-IP is designed with versatility in mind, making it suitable for various applications, from small fabrication shops to large manufacturing facilities. Its modular design allows for customized setups, catering to specific operational needs.

In summary, Miller Electric RPC-IP is more than just a power distribution system; it is a comprehensive solution that integrates intelligent features, robust safety protocols, and seamless connectivity. This makes it an essential tool for any welding operation looking to improve efficiency, safety, and overall productivity in today’s competitive industrial landscape.
