For Stick and TIG welding Direct Cur- rent Electrode Positive (DCEP), con- nect electrode holder cable to Positive

(+)terminal on left and work cable to Negative (−) terminal on right.

For Direct Current Electrode Negative (DCEN), reverse cable connections.

If equipped with optional polarity switch, connect electrode holder cable to Elec- trode terminal on left and work cable to Work terminal on right.

For MIG and FCAW welding Direct Cur- rent Electrode Positive (DCEP) on CC/ CV models, connect wire feeder cable to Positive (+) terminal on left and work cable to Negative (−) terminal on right. Use Process/Contactor switch to select type of weld output (see Section 7-3).

For Direct Current Electrode Negative (DCEN), reverse cable connections.

If equipped with optional polarity switch, connect wire feeder cable to Electrode terminal on left and work cable to Work terminal on right.

*This chart is a general guideline and may not suit all applications. If cables overheat (normally you can smell it), use next size larger cable.

**Weld cable size (AWG) is based on either a 4 volts or less drop or a current density of at least 300 circular mils per ampere. ( ) = mm2 for metric use

The Big Blue 602P, on the other hand, stands out for its high output and exceptional reliability. With a maximum capacity of 600 amps, this machine is designed for heavy-duty applications, making it perfect for industrial settings. The welder features advanced cooling systems and robust construction, which enhance durability and longevity. One notable characteristic of the 602P is its ability to handle various welding processes, including Stick, TIG, and MIG, making it a versatile tool for skilled welders. Additionally, the Big Blue 602P incorporates advanced inverter technology, resulting in a lighter and more energy-efficient model without compromising power performance.

All three models benefit from Miller's commitment to innovation and user-centric design features. Built to thrive in tough work environments, the Big Blue series is equipped with protective casings and vibration-resistant components. Safety is also a priority, with several built-in features that help protect users during operation.

In summary, the Miller Electric Big Blue 502P, 402P, and 602P each bring unique strengths to the welding market. Their notable features include advanced technologies, robust construction, and versatile applications, ensuring that professionals have the right tool for any welding job. Whether for light-duty tasks or heavy industrial applications, Miller Electric's Big Blue series remains a cornerstone for welders around the globe.
