Sign up for Parkworld 50ft NEMA 6-30 Extension Cord - 30A 250V Flat Cable For Welders & Heaters, Heavy Duty
Need to power your welder, heater, or other 30A equipment farther from the outlet?
This Parkworld extension cord is built for that.
It's a 50-foot flat cable with NEMA 6-30 plugs on both ends—male and female connectors are lighted and have rotatable handles for easy pulling.
Important: this is for 250V NEMA 6-30 outlets ONLY (common for workshops, not regular household outlets—the plug is larger than a standard 6-15).
The cord uses 10/3 AWG stranded copper wires inside, rated for up to 30 amps and 7500 watts max.
Connectors are nickel-plated brass to resist rust.
The flat design makes it easier to roll up and less trippy than round cords.
Works with most welder and heater brands that use a 3-pole 6-30 plug.
Sturdy construction, good for job sites or garages where you need extra reach.
Just match the plug shape to your outlet and equipment—no adapters needed.
Solid performance, no voltage drop issues at this length.Related Products
