300517 - Miller Full KVA Adapter Cord NEMA 14-50P to 6-50R

Maximize Your Engine Drive's Versatility

Expand the capabilities of your mobile welding rig with the Miller 300517 Full KVA Adapter Cord. In the field, flexibility is key, and being able to power your auxiliary equipment from your main engine drive can save time and money. This heavy-duty adapter cord is the perfect solution for connecting 230-volt equipment, such as Millermatic MIG welders and Spectrum plasma cutters, directly to the auxiliary power output of your Miller engine-driven welder/generator.

The adapter is engineered to convert the NEMA 14-50P outlet—standard on many Miller generators like the Bobcat and Trailblazer—to a NEMA 6-50R receptacle. This 14-50P to 6-50R conversion is critical because while the generator provides a four-wire connection (two hots, a neutral, and a ground), most 230V welding machines utilize a three-wire plug (two hots and a ground). This adapter correctly routes the power to ensure your equipment receives the clean, full KVA power it needs to operate at peak performance, rated up to 50 Amps.

Durability is a standard with Miller Electric products, and this adapter is no exception. It features a robust 8/3 wire gauge pigtail that resists wear and tear in harsh job site conditions. The molded connectors are designed to withstand impact and resist moisture, ensuring a long service life. Weighing only 2 lbs, it is a lightweight addition to your gear that solves a heavyweight problem.

Ideal for Field Applications:

• Construction Sites: Run your shop MIG welder on-site using your generator power.
• Fabrication & Repair: Power plasma cutters for quick demolition or prep work without a separate compressor generator.
• Farm & Ranch: Utilize existing engine drives to power various 230V tools and equipment.

Ensure you have the right connection every time with this genuine Miller adapter cord.
